Huamei is a factory with over ten years of production experience. During this period, we will encounter various problems, and the following are frequently encountered:

1. After the tape is attached to the release film, some of the tape peels back and makes a popping sound when peeled off.

2. Anti stripping, the material to be stripped has not been stripped.

3. After being cut and left for a period of time, the tape and release film cannot be peeled off.

4. The surface of the release film is very oily, and I feel that the release layer is easy to peel off.

5. The release film generates static electricity and adsorbs dust during the unwinding and rewinding process.

There are generally the following reasons for the above issues:

1. Noise occurs during peeling, firstly due to excessive release force, and secondly due to uneven coating.

2. Anti stripping is mainly caused by an unsatisfactory combination of release forces. There are two reasons for this. Firstly, the factory inspection of release films is not strict, the inspection equipment is incomplete, and the production process is not stable enough, resulting in significant differences in release forces between products of the same model. As a result, the die-cutting factory used what they thought was a release film due to usage habits. Secondly, the weather resistance of the release layer is insufficient and has undergone significant changes over time.

3. After being attached to the tape, it cannot be peeled off, usually due to uneven coating. Some release films with severe leakage may cause a certain part to have no release effect, resulting in the tape being unable to peel off. This problem should be avoided in round knife die-cutting.

4. The greasy release surface is mainly caused by the system of release agents, and it is not necessarily that greasy things are bad. In fact, some greasy release film surfaces are coated more evenly and have better residual adhesion rates. But some are purely due to poor adhesion, and silicone oil is prone to detachment. These can all be determined through detection.

5. Static electricity problems are usually treated permanently through chemical means in addition to physical methods. Generally, photoelectric grade die-cutting factories have dust-free workshops and anti-static equipment, so the problem is not significant. For those with strict requirements, anti-static coated release films can be chosen.
