1、PE film is inert to the surface of the protected material, so it will not pollute and corrode the protected material. 2、Protection film has good adhesion performance to the protected material, in the process of material handling and processing, the protection film will not buckle and fall off. 3、PE film has good weather resistance and adhesion stability, short-term peeling force does not increase significantly, long-term quality remains unchanged, easy to peel without residue. 4、Low crystal point, no ghost shadow, fish scale pattern.
