1 lower, pe protective film crystal, crystal points less, the manufacturing level of protective film requires more high quality, the protection film is better.
2, the protective film has good weatherability and viscosity stability, after a few days or longer post peel force growth is not significant, easy to remove, the removal is protected without residue retained on the surface, no pictures.
3, a protective film with good adhesion to materials to be protected, in materials handling and processing, protective film, not warped off.
4, the protective film adhesive is inert, not with the adherend surface chemical reaction.
5, meet user requirements of tensile strength, elastic modulus, elongation etc..
