Sound occurs when peeling off, one is the release force is too large, and the second is coating The result of unevenness. 2. Anti-peeling is mainly caused by the unsatisfactory combination of release force. There are two reasons. First, the release film's factory inspection is not strict, the inspection equipment is incomplete, and the production process is not stable enough, which makes the product of the same model release force. Too much difference. As a result, the die-cutting factory used the release film with the release force they thought out of the habit of use.

In fact, the surface of some greasy release films is more uniform and the residual adhesion rate is better. But some are simply because of poor adhesion, and silicone oil is easy to fall off. These can be determined by testing. 5. Static electricity problems, in addition to physical treatment methods, chemical treatments are generally permanent.
