Common problems of PET release film in die cutting process (2)-film supplier
For the above-mentioned problems, there are generally the following reasons: 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 factory inspection of PET release film is not strict, the inspection equipment is incomplete, and the production process is not stable enough, which makes the products of the same model release. Too much difference in force. 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 pasted with the tape, which is generally the cause of uneven coating. Some PET release film missed more serious will make a certain part of the release effect, resulting in the tape cannot be peeled off, die cutting by a round knife This question should be 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 evenly coated and the residual adhesion rate is better. However, some are purely due to 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.
