It cannot be peeled off after being pasted with the tape. Generally it is the cause of uneven coating. The more serious leakage of the release film will cause a certain problem. There is no release effect on the part, so that the tape cannot be peeled off. Die cutting with a round knife should be taboo.　　2. The greasy release surface is mainly caused by the release agent system. It is not that greasy things are not necessarily bad. In fact, some greasy release films are coated more uniformly on the surface and have a better residual adhesion rate. However, some are purely due to poor adhesion, and silicone oil is easy to fall off. These can also be determined by testing. 3. Static electricity problems, in addition to physical treatment methods, chemical treatments are generally permanent. Generally, photoelectric 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.　　4. There is a sound when peeling, one is the excessive release force, and the second is the result of uneven coating. There are many ways to judge whether coating is not available. One of the simpler is to look at the surface of the film against the light in the sun, and the surface coating effect of the film can be seen at a glance. For example, on the surface of a release film produced in South Korea, spots of coating marks can be seen on the surface, and there is an imagination of rainbow. Everyone can go and take a look. 5. The anti-peeling is mainly caused by the unsatisfactory matching of the release force. There are two reasons. First, the release film is not strictly inspected at the factory, 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. Secondly, the weather resistance of the release layer is not enough, and huge changes have taken place over time.
