PET protective film is used a lot. PET protective film is a common release material in manufacturing industries such as adhesives, electronics, film cutting, packaging and printing. What are the factors that affect PET protective film? Do you know everything? There is a huge demand in the Chinese market, but domestic PET protective films are still dependent on imports for high-end products due to the backward substrate and silicon coating technology. 1. Substrate: PET release film is to coat silicone release agent on the surface of the PET film. The quality of the substrate immediately affects its performance. Domestic PET film substrates lag behind overseas in terms of thin thickness control and heat shrinkage. 2. Residual adhesion rate: The residual adhesion rate refers to the force of the release paper after the first peeling and the second peeling. The data obtained after measurement and calculation, the key reflects the actual effect of silicone oil curing. 3. Peeling force: The size of the peeling force immediately affects the characteristics of the PET release film, the general national standard peeling force dimensional tolerance range is ± 15%. 4. Production and processing environment: With the gradual development of various products and the improvement of quality and technology, the cleanliness grade standards for PET protective film are becoming more and more stringent, especially in the electronic film cutting manufacturing industry.
