1. Sound occurs when peeling off. First, the release force is too large, followed by the result of uneven coating.

2. Anti-peeling is mainly caused by unsatisfactory separation force. There are two reasons for this. First, the factory inspection of the release film is not strict, the inspection equipment is incomplete, and the production process is not stable enough, so that the same type of product release force There is too much difference. The die-cutting factory used the release film that they thought was the release force for the purpose of use. Second, the weatherability of the release layer is not sufficient, and it has undergone tremendous changes over time.

3. After the tape is attached, it can not be peeled off, generally the reason of uneven coating. Some of the release film is more serious, so that there is no release effect on a certain part, so that the tape cannot be peeled off, and the die cutting of the round knife should be I am very afraid of this problem.

4. The greasy surface is mainly caused by the system of the release agent, not greasy things must be bad, in fact, some greasy release film surface coating is more uniform, the residual adhesion rate is better. But some are purely poorly sealed, and silicone oil is easy to fall off. These can all be determined by detection.

5. Static electricity problem, generally in addition to the physical processing methods, the chemical treatment is permanent, generally the photoelectric-grade die-cutting factory has a dust-free workshop, there are also equipment to remove static electricity, the problem will not be very big . For more stringent requirements, an antistatic coated release film can be selected.
