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. Second, the weather resistance of the release layer is not enough, and huge changes have taken place over time. 3. It cannot be peeled off after being pasted with the tape. Generally, it is the cause of uneven coating. Some release film missed more severely will make a certain part have no release effect, resulting in the tape cannot be peeled off. The die cutting of the round knife should be This question is very taboo. 4. The greasy release surface is mainly caused by the release agent system. It is not that greasy things must be bad. 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. Generally, photoelectric-level die-cutting plants have dust-free workshops and equipment for removing static electricity. The problem will not be very big. . For stricter requirements, you can choose antistatic coated release film. The above is for the common problems of the matching of pet release film.
