1. After being attached to the tape, it cannot be peeled off, usually due to uneven coating. If the leakage of Release film is severe, it will cause a certain part to have no release effect, causing the tape to be unable to peel off. This problem should be avoided in the die-cutting of circular knives.

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.

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. As a result, the die-cutting factory used the release film they thought was the release force due to usage habits. Secondly, the weathering resistance of the release layer is insufficient and has undergone significant changes over time.

Reechas is a high-tech enterprise founded in 2006 and headquartered in Shenzhen, China. We focus on the development, production, and sales of integrated laminating products, including release films, conformal films, and press pads. These products are widely usedin PCB, FPC,  rigid-flex PCB, 5G PCB, IC substrate, CCL, smart card, copper coin & heat-sink and other industries.
