Matte release film is also known as matte separation film, Matt Membrane, PET matte film, TPX matte release film, fluoroplastic separation film, fluorosilicone release film; PET matte film is based on the original PET transparent film, with appropriate adjustments to the raw material formula and the addition of silicon dioxide, making the release film non-adhesive or slightly adhesive when in contact with specific materials under limited conditions. TPX matte release film is mainly used in FPC flexible circuit boards, die-cutting industries, food packaging, and automotive thermal insulation.
