Common Problems During the Use of Release Film

1. After being attached to the tape, it cannot be peeled off, which is usually caused by uneven application. Some release films that are severely missed can cause a certain part to have no release effect, resulting in the tape being unable to be peeled off. This problem should be avoided in circular knife die-cutting.

2. The oily release surface is mainly caused by the isolation agent system, and it is not necessarily bad for oily things. In fact, some oily release films are evenly coated on the surface and have better residual adhesion. But some are purely poor in sealing, and silicone oil is prone to detachment. These can also be determined through detection.

3. Static electricity problems are generally permanent in terms of chemical treatment, in addition to physical treatment methods. Generally, photoelectric grade die-cutting factories have dust-free workshops and equipment for removing static electricity, so the problem is not significant. For those with strict requirements, anti-static coated release films can be chosen.

4. There is a noise during peeling, which is caused by excessive release force and uneven coating. There are many ways to determine whether to apply or not. The simpler one is to look at the film surface in the sunlight, and the coating effect of the film surface can be seen at a glance. For example, the surface of a release film produced by a South Korean company can be seen with speckled coating marks and the imagination of a rainbow. Everyone can take a look.

5. Anti stripping is mainly caused by the unsatisfactory combination of release forces, which can be attributed to two reasons. 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 excessive differences in release forces between products of the same model. Causing the die-cutting factory to use the release force they thought was due to usage habits. Secondly, the weathering resistance of the release layer is insufficient and has undergone significant changes over time.
