The residual glue of the protective film has a great relationship with the peeling force of the protective film. Generally speaking, the adhesion is proportional to the peeling strength of the protective film. The stronger the viscosity, the worse the peeling strength; in addition, the quality of the adhesive The worse, the worse the peel strength. We usually increase the adhesion additives when applying the film, or replace the glue to reduce the residual glue. The degumming is mostly because the pressure glue used in the protective film product is too sticky, which easily causes degumming when the product is peeled off. Our users can wipe with alcohol and wipe off the pressure glue. In short, in our daily operations, we should not think that the protective film is just a thin piece of plastic. Each product has its own different film requirements, so we must not be careless when applying the film!
