PET release film is a commonly used material in the industries of gluing, electronics, die cutting, printing, etc.; China has a large market demand every year. However, due to the backwardness of the substrate and silicon coating technology, the domestic PET release film still relies on imports. The main factors affecting the quality of PET release film are the following factors:
1. Substrate: PET release film is coated with silicone release agent on the surface layer of PET film. The quality of the substrate directly affects its performance. Domestic PET film substrates lag behind foreign countries in terms of thickness control and heat shrinkage.
Second, the residual adhesion rate: residual adhesion rate, refers to the force of the release paper after the first peeling, the second peeling, the data obtained after calculation, mainly reflects the effect of silicone oil curing.
Third, the peeling force: the size of the peeling force directly affects the performance of the PET release film, the general industry standard peel force tolerance range is ± 15%. Dongguan Hongyuan Film Co., Ltd. has been engaged in the PET film industry for many years. It has rich experience in various PET materials and professional technical control, which can well control the peeling force stability of the release film.
Fourth, the processing environment: With the advancement of various products, the improvement of quality technology, the cleanliness requirements of PET release film are becoming more and more strict, especially in the electronic film cutting industry. Dongguan Hongyuan Film Co., Ltd. all products are produced in the 10,000-class clean room, and the quality is leading.
