Why does the surface polymer protective film have residual glue

It is a very important thing that the protective film of the wholesale polymer protective film is used to cover the surface of the product, but it will also have residual glue. Why does this happen? The reason for participation is more complicated, because it is caused by different mechanisms. However, one of the more common reasons is that the peel strength of the protective film has changed, because after the polymer protective film is pasted, it takes a while to peel off, and the length of time varies. Another reason is the aging of the protective film, which mainly includes thermal aging and ultraviolet aging. After aging, the macromolecular chains of the substrate and the pressure-sensitive adhesive will be broken, which only causes the corresponding damage, so the quality of it must be improved in the production. The reasons for the residual glue of the polymer protective film are these two, so we must pay attention to protecting its quality in the process of production and use.
