In the process of packaging and paper products processing, static electricity is a common topic. With the mass production of RFID tags on broader and faster printing presses, electrostatic control has become an increasingly important issue.
With the emergence of radio frequency identification technology, radio frequency tag (RFID) has also entered the paper products processing industry. Equipment suppliers want to become the industry's leading provider of RFID solution, which has led to the rapid promotion of this technology throughout the industry. The application range of RFID tags is infinite. Although it can bring countless opportunities to people, it will also bring a certain degree of challenge to people with the increase of the number of users.
Most label and trademark processors are asking, "What exactly is a RFID tag?" Radio frequency technology is a method that can store and retrieve data remotely. It uses radio frequency label as its carrier. The tag contains an antenna that receives and reflects radio waves from radio transceivers. According to the different power supply mode of radio frequency tag, it can be divided into two kinds, and one is active RFID tag, the other is passive RFID tag. Active RFID tags contain built-in batteries, while the latter do not contain built-in batteries. Built-in batteries can send clear signals far away, but RF tags which can send far are also relatively large in size and more expensive than passive RF tags.
Problem
In the process of packaging and paper products processing, static electricity is a common topic. For example, vertical cutting, printing and coating are all related to static electricity.
Electrostatic charge is produced by the contact and separation of materials during different stages of production and treatment. When materials contact and separate from each other, the friction between them (friction electrification) will produce surface charges, or static charges. From the definition, electrostatic charge is the residual charge caused by charge imbalance. This charge is usually generated on insulating materials, such as film or coated paper, or on conductive surfaces isolated from the ground. This is important because many material suppliers claim that their new antistatic materials can protect RF chips from static charges. Unfortunately, their statement is not entirely correct, because electrostatic charges can be transferred to conductive objects isolated from the ground. Once such a conductive object (such as a radio frequency chip) is close to the ground, the transfer of charge can cause damage to the object.
