Analysis on the Structure of High Temperature Bar Code Label

　　High temperature resistant bar code labelWith polyimide film as the substrate, coated with special pressure sensitive adhesive. It has good chemical and abrasion resistance and can withstand up to 320. It has a certain anti-corrosion effect on chemical substances such as flux, melting agent and cleaning agent, and the high temperature resistant bar code label can maintain excellent performance when used in extremely harsh environments such as high temperature and wear.

High temperature resistant bar code label consists of three parts: substrate, adhesive and substrate.

Substrate: 25 micron (or 50 micron) coated treated polyimide film. The polyimide without coating treatment can not meet the performance requirements, and the coating treatment can better meet the requirements of bar code printing and material color and gloss.High temperature resistant bar code label

Adhesives: At present, adhesives are generally divided into three categories: rubber, acrylic, and silicone. Rubber has low cost, poor temperature resistance and chemical resistance, outstanding aging resistance, and superior silicone performance, but it is outstanding. expensive. Acrylic adhesives have temperature resistance of about 200 degrees, good chemical resistance and oxidation resistance, and are affordable. Nowadays, 90% of the adhesive of some brands of tape is made of acrylic. High temperature resistant bar code label using permanent acrylic pressure sensitive adhesive.

Substrate: Glassin release paper, cupronickel release paper, silicon yellow release paper and polyester release film

MostHigh temperature resistant bar code labelUsed in special industrial environments, such as SMD circuit board installation, manufacturing execution system, hot-rolled steel in the iron and steel industry, aluminum industry, ceramics and other industries; As the carrier of bar code and text, high temperature resistant bar code labels need to realize visual identification of production process control, automatic management of bar code and quality traceability, not only high temperature resistance, but also chemical corrosion resistance, friction resistance and super viscosity characteristics in special environments. Can be used for thermal transfer of bar code printers, commercial labeling machines and rotary printing machines, etc.

Circuit board label: electronic circuit surface mount process, can be printed by thermal transfer printing, display better and first-class reading speed. Even if the label board is removed directly from the environment by solder,High temperature resistant bar code labelIt is still resistant to pollution.

If the label is preheated, it can further resist various chemicals, such as soldering agents, melting agents and cleaning agents, as well as extremely harsh high temperature and wear environments, and ensure good performance in various extremely harsh application environments.
