Analysis of common problems of PET release film. Regarding the use of PET release film for die cutting, the following problems are often encountered: 1. After the tape is attached to the release film, some of the tape peels off when it is peeled off, and pops and pops. The sound. 2. Anti-peeling, the peeled material does not peel off. 3. The tape and release film cannot be peeled off after being punched and placed for a period of time. 4. The surface of the release film is very oily, and the release layer feels easy to fall off. 5. The release film generates static electricity during the unwinding and rewinding process and attracts dust. In view of the above-mentioned problems, there are generally the following reasons: 1. When the Dongguan PET film is peeled off, the sound occurs, 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 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. 3. It cannot be peeled off after being attached to the tape.

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. 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. Generally, photoelectric-level die-cutting plants have dust-free workshops and equipment for removing static electricity. The problem will not be very big. .
