What are the common uses of PET release film?
- Feb 21, 2019 -

With the rapid development of the national economy, PET release film has been widely used in packaging, reflective materials, waterproof materials, medicine (paste paper), sanitary paper, pad printing, nameplate, membrane switch, flexible circuit, insulation products. , circuit boards, laser anti-counterfeiting, electronic, sealing materials, adhesive products, printing, silk screen, die-cutting processing and many other industries, has been closely related to our lives.
The PET release film is made of a PET film as a base material and coated with a release agent on the surface. According to the different type of release agent, it is divided into many types. Commonly, there are silicone release agent, fluorine release agent and silicon-free release agent. The silicon content of the silicone PET release film is controllable, and the peeling force is adjustable. High temperature, solvent resistance and good stability.
PET release film is commonly used in plastic die-cutting process, high-strength pressure-sensitive adhesive transfer substrate, protective film for multilayer circuit board manufacturing, protective film for preventing rubber products from bonding to each other, and press forming of conductive materials. Used for the separation of materials from molds; the back layer of high-adhesive tape, such as the insulation layer of foam tape; protects and isolates the plastic products during molding, makes the products easy to peel off, and prevents the products from sticking to the mold The top makes the surface of the product uneven.
