What is PET Matte Silicone Release Film?
PET Matte Silicone Release Film is a clear or ultra-clear polyester film coated with a matte silicone layer. It provides ultra-light release force and excellent surface cleanliness. This film is suitable for applications requiring minimal release force, such as sensitive adhesive products, and maintains stability even under aging conditions.
