Flame retardant, low smoke and halogen-free cross-linked cable material is a new type of environmental protection cable material that emerged in recent years after people enhanced their awareness of environmental protection. The traditional insulation material of wire and cable is mainly polyvinyl chloride, but polyvinyl chloride contains halogen. Accident combustion of wire and cable will release toxic smoke, seriously pollute the environment, and hinder fire fighting and evacuation of firefighters.

Environmental protection wire and cable refers to the wire and cable with "green" insulating material. These "green" insulating materials do not produce harmful substances when burned. Flame retardants do not contain halogens. Additives containing harmful heavy metals are not used, plasticizers for ordinary PVC are not added, and toxic gases are not emitted during daily operation. It has good heat aging resistance, acid and alkali resistance, water resistance, high temperature resistance and flame retardancy. It is used in locomotive cables, oil platform cables, marine cables, photovoltaic cables, nuclear power cables, high-rise buildings, subway, stations, airports, power stations and shopping malls and other relatively closed or concentrated important buildings and facilities.

According to the characteristics of environmental cable materials and years of design and development experience, Nanjing KY Chemical Machinery Co., Ltd. can provide special equipment for mixing and modifying granulation of environmental cable materials according to customer requirements, which can provide guarantee for customers to quickly occupy the commanding heights of the industry.

Mixing Modification of Elastomer——Blending Modification of SBS/SEBS

Applications of Thermoplastic Elastomer:

The English acronym of Thermoplastic Elastomer is TPE. In the Chinese market, TPE refers to SBS/SEBS blending modification materials. Because SBS/SEBS elastomer usually has high viscosity and is difficult to be directly processed, TPE thermoplastic elastomer material (TPS) is prepared by blending SBS/SEBS with plasticizer oil, reinforcing resin, compatibilizer, functional assistant, compatibilizer and so on. Compared with SBS/SEBS, the modified TPE has lower viscosity, higher plasticity, easier processing and moulding. It also has a wide range of adjustable hardness and physical properties. And it does not need vulcanization, can be recycled to reduce costs and other characteristics, so the application field is more extensive. It is mainly used in all kinds of seals, automotive interiors, glue-coated materials, all kinds of pipe fittings, wires and cables, etc.

According to different hardness requirements, SBS or SEBS blending modification adjusts the proportion of SBS/SEBS, PP, filler and filling oil. Increased rigidity of PP, SBS/SEBS and filling oil can improve flexibility.

Features of Thermoplastic Elastomer:

Design of screw barrel with large aspect ratio. Large aspect ratio L/D=48:1-52:1 provides longer residence time, which is beneficial to the melting of resins and elastomers, homogenization and mixing of filling oil and polymers.

High-precision screw and barrel design. The clearance between screw and barrel is small, the dimension accuracy is high, and the screw structure is optimized to effectively complete the mixing process of resin melting, filler dispersion and filling oil homogenization.

Cutting method. At present, the underwater granulation device at home and abroad has been continuously improved, which basically meets the requirements of different hardness, so underwater granulation is adopted.

Mixing modification of elastomer——Description of TPV dynamic vulcanization process

Applications of Thermoplastic vulcanizate:

Thermoplastic vulcanizate is referred to as TPV in short. It is a process that combines some properties of vulcanized rubber with processing properties of thermoplastic plastics. At present, the common components are PP, EPDM, filler, filler oil, crosslinking agent and processing aids. The so-called dynamic vulcanization refers to the simultaneous vulcanization (crosslinking) and melts dispersion of rubber. In the continuous phase of the vulcanized rubber phase uniformly dispersed resin, the particle size of the dispersed phase is 1-2 micron under the appropriate temperature field and shear field, which puts forward very high requirements for the blending equipment and preparation technology. TPV products are mainly used in all kinds of seals, soles, pipes, wires and cables.

Features of twin-screw extruder:

The twin-screw extruder with high speed and high torsion is adopted. High torque can withstand larger loads and adapt to the characteristics of high strength of vulcanized rubber melt; high screw speed provides a higher shear rate, which disperses vulcanized rubber into small rubber particles and evenly disperses in resin.

Screw barrel with large aspect ratio and multi-way metering feeding. Large aspect ratio L/D=48:1~52:1 provides longer residence time, which is conducive to completing the melting homogenization, vulcanization and dispersion of complex mixing process. At the same time, it is equipped with multiple groups of metering feeders to feed resin, rubber, filler, filling oil and crosslinking agent into the barrel step by step.

High-precision screw and barrel design. The clearance between screw and barrel is small, the dimension accuracy is high, and the screw structure is optimized. The melting process of resin and the homogenization process of filling oil are effectively completed, and the dynamic vulcanization process is completed by shearing and dispersing components.

Cutting method. At present, the underwater granulation device at home and abroad has been continuously improved, which basically meets the requirements of different hardness, so underwater granulation is adopted.

The above introduction is a one-step dynamic vulcanization process, which is suitable for the production conditions with stable formulation ratio. In actual production, due to the different requirements of product performance, the proportion of each component in the formulation varies greatly, and the proportion and degree of vulcanized rubber are also quite different, so the two-step dynamic vulcanization process will have stronger applicability. Two twin-screw extruder production lines:

The upper twin screw mixes PP, EPDM, filler and a small amount of filling oil evenly and granulates.

The lower-order twin-screw mixes the homogeneous polymer, most of the filling oil and crosslinking agent to complete the crosslinking of EPDM and disperse it evenly.

Thermosensitive material is a kind of material with poor thermal stability. It is sensitive to temperature and easy to decompose, degrade and discolor at high temperature. When decomposed, it releases corrosive or toxic gases. It is necessary to strictly control the processing temperature (e.g. polyvinyl chloride, polyformaldehyde, EVA and copolymer of vinyl chloride, etc.).

Because of its good insulation and stable chemical properties, this kind of material is widely used in the fields of electronics, electrical appliances, automobiles, transportation, aerospace manufacturing, national defense and military industry. In the production process of twin screw, high speed shear and high pressure will lead to the increase of local temperature of materials, which directly affects the processing of heat sensitive materials.

Design principles for the runner system:

1. For the single plastic part and multiple cavities, the balanced runner (except special) should be used, that is, the position of each cavity gate and the size of the gate point are the same and the length of the runner is the same. To ensure uniform molding conditions in each cavity.

2. For multi products and multi cavities use non-equilibrium runner and gate point, the size of the nozzle or runner should be adjusted according to the distance of the flow to ensure that the cavities are filled as much as possible.

3. In order to reduce heat and pressure loss, the runner should be as short and straight as possible, and the radius should be added at the corner to ensure smooth flow. The surface of the runner must be polished with more than 600# sandpaper. If the part is mirrored, the runner must be polished with 1000# sandpaper.

4. The gate system should be designed cold slug well to prevent cold material entry into the cavity and affect the quality and appearance of the parts.

5. The gate system must be vented to ensure that the plastic melt fills all corners of the cavity, so that the cavity gas can be discharged smoothly.

6. The gate system should be able to prevent the plastic parts from shrinking mark, deformation, dimensional deviation and other defects. The gates are convenient to cutoff or cut automatically and do not affect the appearance of the product.

7. In order to improve the mass production efficiency, it is necessary to minimize the subsequent processing of the plastic parts when designing the gate. Automated mass production, when the gate is taken out, the robot is used as much as possible to shorten the cycle time.

8. For the plastic injection molding gate design, the diameter of the root should be no smaller than the runner. For materials with high brittleness such as PS, a double-sided 3° draft angle should be used. Preventing the breakage of the sprue and runner, while the runner breakage will cause trouble for mass production.

9. Making runner into a circular or U-shaped that is easy to process.

10. The design of the gate system should take into account the amount of runner material. To save costs and eliminate waste, the weight of the runner is controlled below 25% and cannot exceed 50% (special consideration for special parts).

11. When there are multiple injection points on a product, the influence of the size and position of the welding line on the strength and appearance of the product should be considered.

12. For a multi-cavity plastic mould, reasonable, symmetry and compact positioning is able to prevent the eccentric load, reduce the mold base dimension and the tonnage of the molding machine.

13. For a multiple products mould which is also called family mold, the size of the gate must be adjusted according to the plastic parts dimension to ensure that each product is filled simultaneously.

14. For the complicate product, it's necessary to make mold-flow analysis to help design a good runner system and gate position.

Design standard for Sprue:

1.Injection molding machine nozzle and sprue matching

The spherical surface SR of the mold sprue should be 1-2MM larger than the nozzle SR of the injection molding machine. The SR of the nozzle can be found in the specifications of the injection molding machine.

Attention: When designing the mold, check the length of the nozzle of the molding machine that can be inserted into the mold. Should make proposal if have to use the extended nozzle.

2.Sprue diameter ⌀D setting

The sprue D should be 0.5mm larger than the the nozzle of the injection molding machine.

3.To shorten the sprue, we have to:

A.For two plate mould, sprue should be sunk in to the A plate (except for special customer requirements).

B.For three plate mould, big spue bush is must if the sprue length is 25mm or more.

C.Plastic parts with appearance requirements and other special requirements use hot sprue.

Design standard for Runner:

1.Type of runner.

A.Round runner.

B.U shape runner.

2.D series: 2 2.5 3 3.5 4 4.5 5 6 7 8 (10 12 reference use)

3.The runner diameter setting

For PE, PA, the diameter can be small. For PC, PMMA, the diameter value can be a large value.

Estimation diameter according to experience

4.Precautions

A.In the U-shaped runner, the size of the runner can be changed by

adjusting the H value.

B.Use round runner whenever possible

C.The runner must be thicker than the section of the subordinate

runner (see table below), if the secondary runner increases,

D1 diameter can be reduced according to the actual situation.

Design principles for common gates:

The form, position, size and number of nozzles should fully meet the requirements of mold processing and parts production.

1.Direct gate

1. Low pressure loss, easy to fill
2. The pressure at the gate is large, which will cause deformation.
3. It is difficult to remove the nozzle
4. Common gate
5. Easy mold processing
6. Correction is easy
7. Thin and long barrel products should not be used.
8. It is necessary to take care that whether the subsequent processing of the nozzle is convenient and whether the residue after processing will affect the appearance and function of the product.
9. Pin point gate
10. Flexible to select the gate location.
11. Small residual stress near the gate
12. After the mold is opened, the gate can be pulled off by itself. The traces left on the plastic part are not obvious, and the appearance of the surface of the plastic part is not affected.
13. The flow rate of the molten plastic flow through the gate is increased, and the frictional force acts to increase the temperature of the plastic stream. In this way, a plastic part with a clear shape and a glossy surface can be obtained.
14. Injection pressure loss is large, which is not good for plastic molding.
15. The mold structure is more complicated, and the double parting line mold (three plate mold) is generally used to remove the sprue.
16. Because the high flow velocity near the gate, the molecules are highly oriented, and local stress is increased, which may cause cracking. Therefore, without affecting the function of the plastic part, increase the wall thickness of the plastic part opposite the gate.

H.Warpage wil occur when a large plastic part adopts a point gate, so multiple point gates should be used at

the same time.

4. Sub-gate
5. Gate can be located inside or outside of the plastic product, the gate is usually located at the bone position of the injection molded product, the gate is concealed and does not affect the appearance of the injection molded part.
6. Small gate mark.
7. Gate is cut automatically.
8. There is a problem of large pressure loss.
9. Large flow resistance.
10. Fan gate
11. Good liquidity.
12. Can be evenly filled to prevent deformation of plastic parts.
13. The plastic parts look good.
14. Gate is not easy separate.
15. Large gate residue
16. Suitable for large and thin-walled plastic parts.

Slug well design

The location of the slug well is generally designed at the end of the sprue and runner.

That is, the first place where the melt plastic arrives, and venting is must added.

The design of the slug well varies depending on the different gate type.

Ejection of sprue

Normally, designer should have a thorough understanding of material properties, choose the most suitable solution.

1、Technical principle

The curvature radius of the aspheric lens changes with the center axis. It can be used to improve optical quality, reduce the number of optical components and reduce design costs. Compared with spherical lens, aspheric lens has unique advantages, so it has been widely used in optical instrument, image and photoelectron industry, such as digital camera, CD player and high end micro instrument.

2、Comparative advantage

a, Spherical aberration calibration

The most remarkable advantage of aspheric lenses in replacing spherical lenses is that they can correct the spherical aberration caused by spherical lenses in collimating and focusing systems. By adjusting the surface constant and the aspheric coefficient, the aspheric lens can eliminate spherical aberration to the maximum extent.Aspheric lenses (rays converge to the same point and provides optical quality) basically eliminate spherical aberrations produced by spherical lenses (rays converge to different points and leads to blurred imaging).

Three spherical lenses are used to increase the effective focal length, which can be used to eliminate spherical aberration. However, a aspheric lens (high numerical aperture, short focal length) can be realized, and it can simplify the system design and provide the light transmittance.

b, System advantages

The aspheric lens simplifies the elements involved in optical engineers to improve the optical quality and improves the stability of the system.For example, in zoom systems, 10 or more lenses are normally used (additional: high mechanical tolerances, additional assembly procedures, and the improvement of antireflection coating). However, one or two aspheric lenses can achieve similar or better optical qualities. This reduces the system size, increases the cost rate and reduces the overall cost of the system.

3、Moulding techniques

a, Moulding of precision glass

The molding of precision glass is to make the glass material heated to high temperature and become plastic, and then molded by aspheric mold, and finally gradually cooled to room temperature.At present, the molding of precision glass is not suitable for aspheric lens with diameter greater than 10mm. However, new tools, optical glass and metrology process are driving the development of the technology. Although precision glass molding at the beginning of the hyp design has high cost (high precision mold development), but after the molding, the production of high-quality products can be split off the pre development costs. It is especially suitable for the needs of mass production.

b, Forming of precision polishing

Lapping and polishing are generally applicable to the production of monolithic aspheric lenses at one time. With the improvement of technology, the accuracy is higher and higher.The most remarkable thing is that precise polishing is controlled by computers and automatically adjusted to optimize parameters.If higher quality polishing is required, magnetorheological finishing (magneto-rheological finishing) will be adopted. Compared with standard polishing, magnetorheological finishing has higher performance and shorter time.Precision polishing molding technology need professional equipment. It is currently the first choice of sample production and small batch sample.

c, Hybrid molding technology

The hybrid molding is a spherical aspheric lens with a spherical lens as the substrate, which is cast on the surface of the spherical lens through an aspherical mould and cured by a layer of high polymer with UV light.Mixed forming is generally used the achromatic spherical lens as the base, and then a layer of aspheric surface is cast on the surface to eliminate chromatic aberration and spherical aberration simultaneously.Figure 7 is the manufacturing process of the hybrid aspheric lens. The hybrid aspherical lens is suitable for large scale manufacturing with additional characteristics (eliminating chromatic aberration and spherical aberration) .

d, Injection molding

In addition to glass aspherical lenses, there are plastic aspheric lenses.Plastic molding is the injection of molten plastics into aspherical molds.Compared with glass, the thermal stability and compressive resistance of plastics are poor. It requires special treatment to obtain similar aspherical lenses. However, the plastic aspheric lens is characterized by its low cost, light weight and easy molding. It is widely used in the fields of moderate optical quality, insensitive to thermal stability and little pressure resistance.

4、Basis of choice

All kinds of aspheric lenses have their own relative advantages. Therefore, it is very important to choose the right products for different applications. The main considerations include: batch, quality and cost.

Plastic medicine bottles are the most common drug packaging. It can store both solid and liquid medicines. In the 1980s, most of the bottles produced by plastic bottle manufacturers all over the world use glass bottles and metal swing-open lids. The advantages and disadvantages of plastic bottle manufacturers producing plastic medicine bottles.

Plastic medicine bottles are the most common drug packaging, which can store both solid drugs (such as tablets) and liquid drugs (such as potions). In the 1980s, most of the bottles produced by plastic bottle manufacturers all over the world used glass bottles and metal swing-open lids. The biggest drawback of this type of bottle is that it is not resistant to long-distance transportation.

The crushing rate is high, and the bottle cap is not tightly closed, which may cause liquid leakage, microbial contamination, and mildew of the internal liquid. In western countries, pharmaceutical manufacturers have replaced old-fashioned glass bottles with plastic bottles and caps made of highly transparent polyester. These newly developed vials are not only highly transparent, but it is also resistant to falling, impact, and biocompatibility. Some of them are easy to open due to the use of capping technology. However, the pull-type transparent plastic bottle also has a disadvantage: it is easily opened by children and causes accidental poisoning. To this end, some foreign manufacturers have designed anti-child open-type plastic bottles.

The introduction of the advantages of wood plastic composite decking floor:

1. Long service life: The service life of wood plastic composite decking flooris three to four times higher than that of ordinary wood, that is to say, it can be used for 10 to 50 years. It has a long use time, so the wood plastic composite decking floor is more cost-effective naturally.

2. Loss is lower than wood: the use of wood in then wood plastic composite decking floor is less than the ordinary wood under the same conditions. And wood plastic composite decking floor is mostly hollow specifications, which can save more production materials. At the same time, the cost of the hollow sheet is lower, and the price will be more favorable. Hollow profiles also have the advantage of reducing their own weight and load-bearing capacity. These are the advantages of wood plastic composite decking floor, while the ordinary wood can not do.

3. Maintenance cost is low: the performance of common solid wood needs to be protected by painting, and some protective paint is also applied in subsequent use, otherwise, it will affect the service life. The wood plastic composite decking floor does not need this process, and it can be used after processing. It does not need painting, and the waterproof performance is also very good. Maintenance costs are much lower than wood products.

4. Environmental protection products can also be reprocessed: wood plastic composite decking floor use eco-wood, environment protection wood, and is renewable, and does not contain toxic substances, and can be processed. The products can be sawn, planed, bonded, fixed with nails or screw, etc. The installation is very convenient.

5. Exterior color diversity: It has a natural texture of wood, and can also achieve personalized modeling, and has diverse product color, and will not produce cracks, warping, deformation during the, and also has no wood scar.

XPE baby mat, also known as semi porous foam pad, uses ultra-high pressure polyethylene material. This material is not a high-grade material of pure EVA. Its strength, toughness and tensile strength are much better than those of closed cell foam. Therefore, manufacturers use it to make moisture-proof pads, in the high-temperature processing of hard shell processing, to improve water resistance. The shell treatment (embossing) pad not only enhances the appearance and water resistance, but also improves the toughness, and groove pattern, good air permeability. XPE is a new breed introduced in the past two years. Its price is slightly higher than that of foam material. Its comfort has obvious superiority. It can be said that the ideal type of damp proof pad is low.

But XPE palstic is not as dense as plastic foam in appearance, but it feels a bit rough. It often makes people feel a little uncomfortable, but in fact it is not. XPE's greatest advantage is that it does not add toxic chemicals to its materials and does not produce a disgusting odor. This is the real reason for its higher price. XPE baby mats are generally economical and practical products. Some products need a layer of Aluminium foil to enhance the warmth, but please note that the cost of Aluminium foil is not high.

Plastic medicine bottle manufacturers explain the production standards for plastic bottles. In recent years, China's plastic medicine bottle packaging has developed rapidly. Plastic medicine bottles have the characteristics of lightweight, no damage, health, etc., plus special requirements for pharmaceutical packaging. At present, pharmaceutical tablets, capsules, and packaging have gradually realized the replacement of "glass" with "plastic".

The dose of plastic bottles produced, if used improperly, the migration of trace elements will change the medicinal efficacy of the drug, and taking drugs may even be life-threatening. Medicines are a special kind of goods. The manufacturers of plastic medicine bottles must be strictly controlled from every stage of production, meet the requirements of health and compliance with "GMP", and have relevant laws and regulations.

At present, most plastic pharmaceutical bottles, tablets, capsules, pharmaceutical packaging, so the production of plastic bottles must ensure pharmaceutical tablets. Capsules are difficult to be deteriorated by moisture, heat-resistant melting, explosion, not easy to change color when exposed to light, decomposition, oxidation, and pollution. Plastic bottles are available in high-density polyethylene bottles (HDPE), polypropylene bottles (PP), polycarbonate bottles (PC), and polyester bottles (PET).

Air tightness and moisture permeability play a vital role in the stability of charging. Plastic bottle product quality standards. Product quality analysis is performed from the manufacturer's product quality standards to determine if it is desirable. Plastic pharmaceutical bottle enterprises should set corporate standards higher than national standards, and industry standards are more stringent. Select the main raw material of the plastic bottle, the additive formula: the product standard of the solid plastic bottle is the applicable rule of the main raw material, and must conform to non-toxic, no odor and so on.

Plastic bottle stability and compatibility. The use of plastic bottles, especially when drugs using new plastic bottles (or new materials, new processes), should be packed with advanced drug testing to check the stability and charge of the plastic bottle with drug compatibility. Medicine plastic bottles interpenetrating, dissolving, adsorbing, chemically reacting, and denature can be determined by scientific testing.

The raw materials of plastic medicine bottles need to meet the requirements of medical and health. The commonly used plastic materials are polyethylene (PE), polypropylene (PP), polyester (PET) and so on. These materials have this different feature. Polyethylene (PE) is corrosion resistant and can be chlorinated.

Polyethylene is classified into high density (HDPE), low density (LDPE), and linear low density (LLDPE). HDPE has a higher melting point, hardness and strength, low water absorption, good processability, and radiation resistance, and is often used in the production of plastic bottles for tablets; LDPE has better flexibility, elongation and impact strength.

A plastic medicine bottle that can be used for eye drops; LLDPE has high impact strength, fatigue resistance, and abrasion resistance, and is less used in medical packaging. High-density polyethylene bottle polypropylene (PP) has low density, superior strength, hardness, and heat resistance than high-density polyethylene, but it becomes brittle at low temperature, not wear-resistant and easy to age.

However, the corresponding additive can be added for modification, and the functional level of HDPE can be achieved after modification. Polypropylene bottle manufacturer PET has many advantages as a pharmaceutical packaging container. First of all, PET bottles are light and strong, and their strength and elasticity are significantly higher than those of plastic bottles made of plastic materials. It is better to isolate water vapor and oxygen in common plastics.

The airtightness of clear plastic medicine bottles is important for the drug to be protected from moisture and deterioration during the period of validity, and is also an important medium for preventing the influence of light, heat, and oxygen on drugs. Therefore, as a plastic pharmaceutical bottle manufacturer, we attach great importance to its air tightness testing.

What is the airtightness of clear plastic medical bottles? Simply speaking, it is tested according to relevant national standards. For example, the reliability of detecting the plastic bottle seal of a capsule is obtained by taking a certain amount of capsule plastic bottles, and each bottle is filled with a suitable amount of glass balls and screwed the cap. Then, place it in a container with a suction device, immerse it in water, and evacuate it to a vacuum of 27 kPa for 2 minutes. There must be no water or bubbles in the bottle. Of course, to ensure that the airtight plastic bottle capsules are indexed, some other economic indicators such as sex, moisture resistance, and moisture control are needed to ensure the quality of the shelf life products.

Nowadays, there are also machines for introducing a seal tester on the market. The vacuum of the principal chamber of the vacuum cleaner is used to make the sample of the medicinal plastic bottle submerged in the water producing a pressure difference between the inside and the outside of the sample, and the gas inside the sample is observed to escape to determine the sealing performance. Or through the vacuum chamber of the vacuum, make an inside and the outside pressure difference of the sample, observe the inflation of the sample, and the recovery of sample shape after vacuum release, in order to determine the sealing performance.

Along with the influence of global economic integration, the exchanges and development of economic science and technology around the world have filled the world economy with opportunities and challenges. Since China joined the WTO in 2001, China has gradually integrated into the mainstream of the international arena, and economic and technology have developed rapidly. It has promoted the rapid growth and development of various domestic industries, including the plastic medicine bottle packaging industry.

Today, with the continuous improvement of medical standards and the improvement of medical equipment, plastic medicine bottles are favored as a safe and convenient packaging form. China's plastic medicine bottle packaging industry has been developing for more than ten years. After reviewing the development of more than ten years, the speed is rapid and the results are satisfactory. Looking forward to the future development of the plastic pharmaceutical bottle industry, we need to inject more fresh elements, so that the use of plastic medicine bottles is more and more adapted to the development requirements of the modern market.

The child-resistant open-cap plastic bottle can effectively prevent children from eating drugs accidentally. This type of plastic medicine bottle is not much different from the usual plastic medicine bottle. The only difference is the opening method. Moisture-proof and anti-seepage medicinal plastic bottles: The medicines are easily deteriorated and damaged in a humid environment. The moisture-proof and anti-seepage medicinal plastic bottles can completely prevent the development of such phenomena by using materials that can completely isolate moisture and oxygen and ensure the effectiveness of the medicines.

Anti-counterfeiting plastic medicine bottles: Under the temptation of money, many manufacturers are mad, and they are crazy to produce counterfeit or harmful drugs. If anti-counterfeiting medicinal plastic bottles are used, the development of such phenomena can be effectively reduced, so that profiteers can have no holes. The so-called anti-counterfeit plastic medicine bottle is to implant electronic identity on the plastic medicine bottle.

Information about the product, such as manufacturer, date of manufacture, product lot number, product name, etc., can be easily obtained by scanning. It can be seen that with the rapid development of the times, the plastic medicine bottle packaging industry should also improve update and develop with the times, making the medicinal plastic bottle packaging more and more perfect, more and more foolproof, reducing all kinds of unpleasant phenomena.

The most common shapes for plastic medicine bottles are round, square, oval, and so on. From the point of view of use, they each have their own advantages and disadvantages. Round plastic bottles have a high stiffness but are not aesthetically pleasing. The square plastic bottle has a beautiful appearance, but it is not easy to control the uniform thickness of the plastic bottle during molding. Elliptical plastic bottles have higher stiffness, but the manufacturing cost of the mold is higher. Therefore, in order to ensure the rigidity of the plastic bottle, in addition to selecting a material with high rigidity, the shape of the plastic bottle is also designed to enhance the rigidity and load resistance of the plastic bottle.

Changing the surface shape of the plastic bottle, such as the middle of the plastic bottle is relatively thin, increasing the circumferential groove or rib of the surface of the plastic bottle, which can improve the rigidity and bending resistance of the plastic bottle. Longitudinal grooves or ribs eliminate the offset, sagging or deformation of plastic bottles under long-term load. When designing extruded plastic bottles, if the material is high-density polyethylene or polypropylene, the cross-section of the plastic bottle should be rectangular or elliptical. For low-density polyethylene or other flexible plastic bottles, the cross-section is round better.

This facilitates the extrusion of the contents from the plastic bottle. In order to make the plastic bottle wall thickness uniform, it should be noted that the shape of the plastic bottle should be symmetrical. Minimize extreme stretching points and parts. Arc transitions are used at all transitions. The printed surface of the plastic bottle is the most concentrated part of the consumers. The printing surface should be flat and continuous; if the plastic bottle contains handles, grooves, ribs, and other structures, care should be taken not to bring inconvenience to the printing operation. When the surface of the plastic bottle is marked, the surface of the label should be flat.

A "sash" can be designed on the surface of the plastic bottle to make the label accurately positioned without moving. At the time of blow molding, the portion where the parison inflates first contacts always tends to be hardened first. Therefore, the wall thickness of this part is also larger. The edge and the corner portion are the portions where the parison inflates the last contact, and the wall thickness of the portion is small.

Therefore, the edges and horns of the plastic bottle should be designed to be rounded. Since most plastics have notch sensitivity, plastic bottles are prone to crack at sharp corners, roots of the mouth threads, necks, etc., so these parts should be designed to be rounded.

Plastic medicine bottles are of course a kind of packaging container for medicines, and medicines are the main substance for treating the human body. For plastic bottles containing drugs, various safety inspections are required before they can be used for storing medicines. Medically plastic bottles used for medicine are called plastic medicine bottles. Because some plastic bottles are not very good in material, they will produce carcinogenic substances under the sunlight. The use of all medicinal plastic bottles also requires careful attention. Improper use will not only invalidate the drug but also cause us to indirect injury to the body. Some experts in the manufacture of medicine plastic bottles also pointed out a few points about how to use such packaging containers.

If we need a bottle with high transparency, choose this polyester plastic medicine bottle. If it is a drug that does not need to see light, choose a brown plastic bottle. There are many materials to choose from, and no matter which material the plastic medicine bottle is chosen, it will have a very important impact on the packaged goods. The application of plastic medicine bottles requires professional knowledge. The size and cap of the plastic bottle are specially required, and the cap is made of PP material. Plastic bottles for tablet materials are generally selected from high-density polyethylene. In general, the liquid dosage form of the drug is generally selected from polypropylene or polyester bottles as the main material. The infiltration and secretion of water vapor and the sealing of bottles are important indicators of plastic bottles. Whether they are qualified or not is related to the quality and safety of the drugs. Therefore, the use of plastic medicine bottles is very strict medically. Not all plastic bottles are suitable for packaging medicines. Not only has it been greatly improved in the production of plastic medical bottles, but also a new process has been adopted in the processing of plastic medical bottles, which is of great benefit to users.
