The PET protective film is non-toxic and harmless in the process of use, very hygienic and reliable, and can be directly used in the packaging of food, medicine and medical equipment, and the PET protective film sterilizes its packaged items. It can be recycled and will not produce harmful substances harmful to the environment when incinerated. The PET protective film will not be affected by the environment such as air when in use, so the product is very suitable for packaging materials and has better barrier properties to oxygen and water vapor during use. The thermoforming performance is excellent, which is equivalent to that of PVC sheet. It can be vacuum formed to make PET thermoformed products with excellent performance. PET protective film is used a lot. PET protective film manufacturers are a kind of release material commonly used in adhesives, electronics, die-cutting, printing and other industries. What are the factors that affect PET protective film? Do you understand everything? The Chinese market demand is huge, but domestic PET protective film is still dependent on imports due to the backward substrate and silicon coating technology. PET protective film manufacturers talk about the main factors that affect the quality of PET protective film: 1. Substrate: 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. 4. Processing environment: With the increasing progress of various products and the improvement of quality technology, the cleanliness requirements of PET protective film are becoming more and more stringent, especially in the electronic film cutting industry.
