The structural composition of high-temperature resistant labels should consist of three parts: substrate, adhesive, and substrate.

1. Substrate: 25um (or 50um) coated polyimide film. Untreated polyimide cannot meet the performance requirements. Coating treatment can better meet the printing barcode requirements and the requirements for material color and glossiness in the process.

2. Adhesives: Nowadays, adhesives are generally divided into three categories: rubber, acrylic, and silicone. Rubber adhesives have low cost, poor temperature and chemical resistance, and outstanding aging resistance. Silicone adhesives have superior performance, but outstanding are very expensive. Acrylic adhesives have a temperature resistance of about 200 degrees and good chemical and oxidation resistance. The price is also moderate. Currently, 90% of the adhesives for some brand tapes are made of acrylic. The high-temperature label uses permanent acrylic pressure-sensitive adhesive.

3. Substrate: Gracin release paper, white single copper release paper, silicon yellow release paper, PET release film.

Main application areas: The product is widely used in industries such as electronic manufacturing, aluminum, and aerospace.
