What is the internal factor that PE protective film will remain glue?
The internal factors of glue are divided into the following three points:
①The adhesive base is damaged, there are more rubber residues on the surface of the protected product, and the substrate is visible on the surface of the PE protective film;
②Cohesive failure, pressure-sensitive adhesive is on the surface of the protected product and the substrate, and the adhesive surface of the protective film loses its luster;
③ Migration residue, there is a small amount of pressure-sensitive adhesive residue on the surface of the protected product, and the gloss of the PE protective film coating surface remains good.
