PET release film is one of the most basic auxiliary materials commonly used in the production process. It summarizes several common problems and solutions in the application of PET release film in the die-cutting process. Regarding the die-cutting process, the release film usually encounters the following problems: 1. After the double-sided tape is laminated with the PET release film, some of the double-sided tape will peel off and make a strange sound when peeling off. 2. Anti-peeling means that the peeled material is not peeled off. 3. The tape and release film cannot be peeled off after being punched and placed for a period of time. 4. The releasing force of the release film is very low, and the release layer feels easy to fall off. 5. The PET release film will generate static electricity during the winding process and attract dust. For the above-mentioned problems, there are usually the following solutions: 1. Noise occurs during peeling, one is the excessive release force, and the second is the result of uneven coating. 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 same type of product 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. 3. It cannot be peeled off after being attached to the tape. Generally, it is the cause of uneven coating. Some release film missed more severely will make a certain part of the release effect, resulting in the tape cannot be peeled off, the die cutting of the round knife should Very taboo about this issue. 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 coated more uniformly and the residual adhesion rate is better. But some are purely 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.
