Why does PE protective film produce residual glue?

There are two reasons why PE protective film will produce residual glue: 1. Human factors; 2. It is the internal factor of glue. In the process of using PE protective film, because the choice of protective film is unprofessional, it is easy to cause the residual glue of the protective film because the viscosity of the product is not selected.

1. Human factors: Some people think that PE protective film looks like a layer of plastic film. Any kind of protective film can meet their product needs, or even just think it can be attached. It is very irresponsible It is said that there is still a lot of professional knowledge about PE protective film, such as: maintain the cleanliness of the product, no grease, and no chemical residue on the surface of the product before applying the film, otherwise it will easily cause the residue to react with the glue, resulting in degumming, The phenomenon of insufficient viscosity, etc...

2. The internal factors of the glue can be divided into the following three points: ①The sticky 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 damage, on the surface of the protected product and the substrate There are pressure-sensitive adhesives, and the coating surface of the protective film loses luster; ③Migration 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.
