PET Release Film
A release film made by coating PET film with a silicone-containing release agent. It features stable release force, high temperature resistance, and easy shearing and die-cutting. Depending on different customer needs, suitable release forces and substrates are matched for different types of adhesives and adhesive properties, helping customers solve a series of problems encountered during the production of double-sided tape and substrate-free double-sided tape, such as anti-adhesion, delamination, and difficulty in peeling. It can be widely used in the production of acrylic adhesives, double-sided tapes, and substrate-free double-sided tapes.
