The degumming of PE protective film is more reflected in the glass protective film. When the user tears off the protective film on the glass surface after the glass installation is completed, the adhesive of the protective film is not torn off along with the protective film, but remains on the surface of the glass product.
The above phenomenon may be that the pressure-sensitive adhesive used in the protective film does not meet the requirements, that is, the viscosity is too large, which causes the external tension of the PE protective film to be greater than the internal stress when the product is peeled, and thus remains on the glass surface. At this time, you can use a clean cloth dipped in detergent and repeatedly wipe the remaining pressure-sensitive adhesive until it is clean.
