With the rapid development of the national economy, PET release film has been widely used in packaging, reflective materials, waterproof materials, medicine (plaster paper), toilet paper, pad printing, nameplates, membrane switches, flexible circuits, insulation products , circuit boards, laser anti-counterfeiting lamination, electronics, film for sealing materials, adhesive products, printing, screen printing, die-cutting and punching and many other industries have been closely related to our lives. However, because most of them are auxiliary consumables in the production process, many friends do not know about it, including many company purchasers who do not know its specific use. Below we give a brief introduction to the PET release film and give examples of some of its uses to help you understand.

      PET release film is made of PET film as the base material and coated with a layer of release agent on its surface. According to the different types of release agents, the common ones are: silicone release agents, fluorine-containing release agents and silicone-free release agents. Our company selects high-quality PET film substrate, and the silicone PET release film produced has controllable silicon content, adjustable peeling force, high temperature resistance, solvent resistance and good stability. Its main common uses are:

1. It plays the role of protection and isolation during the molding of plastic products, making the product easy to peel off, and preventing the product from sticking to the mold and making the surface of the product uneven

2. Press molding of conductive materials for isolation of materials and molds

3. The backside isolation layer of high-viscosity tape, such as the isolation layer of foam tape

4. Winding protection material for asphalt pipelines to prevent fouling and clogging of pipelines

5. A release film containing sticky resin material to prevent the resin from adhering to the container when the sticky resin is transported

6. Soft mold in polymer material molding process

7. Protective film for multilayer circuit board manufacturing

8. Plastic die-cutting process

9. Protective film to prevent rubber products from sticking to each other

10. Transfer substrate for high-strength pressure-sensitive adhesive
