The performance requirements of PE protective film are as follows: 1. The protective film has good weatherability and adherence stability, the growth of the long adhesive force is not significant, and it is easy to remove. Two, the protective film has good adhesion to the protected material, and the protective film falls off in the process of material handling and processing; three, the surface of the protected material is inert.

The use of PE protective film:

1. No pollution and no corrosion: the adhesive is inert and will not react with the surface of the sticky material. Two, under the sun exposure, the use period is half a year to one year; three, the peeling force is stable and the time change is small, that is, the smaller the rise of the stripping force is, the better the better.
