PET release film is a material commonly used in adhesives, electronics, die cutting, printing and other industries; China has a large market demand every year. However, the domestic PET release film still relies on imports for high-end products due to the backward substrate and silicon coating technology. The main factors affecting the quality of PET release film are as follows: 1. Substrate: PET release film is to coat silicone release agent on the surface of the 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. 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 calculated data mainly reflects the curing effect of silicone oil. 3. 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. Various PET materials have rich experience and professional technical control, which can well control the stability of the peeling force of the release film. 4. Processing environment: With the increasing progress of various products and the improvement of quality technology, the cleanliness requirements of PET release film are becoming more and more stringent, especially in the electronic film cutting industry. All products of Dongguan Hongyuan Film Co., Ltd. are now produced in 10,000-class dust-free workshops and are divided into strips; the quality is leading peers.
