Why is PE protective film hard to tear after use?

After the PE protective film is glued, it is difficult to peel off the protective film from the product, especially when the PE protective film is torn off after the aluminum profile is installed, the protective film cannot be completely removed, and residual glue will remain. So how do we solve this problem?

If this is the case, the protective film will of course be very effective when it is pasted, but it will be It’s very difficult. This is also the most common problem with the protective film produced by some informal protective film manufacturers.
