What strict requirements are there for product quality during the production process of customized release films?

The uniformity of the thickness of the release film is a crucial quality indicator. During the production process, it is essential that the thickness of the release film remains as consistent as possible across the entire surface. For instance, in certain high-precision applications in the electronics industry, such as the release film used in touchscreen manufacturing, the thickness tolerance may need to be controlled within ±2μm. This is due to the fact that uneven thickness can result in inconsistent release forces during subsequent use, which can affect the adhesion and separation performance of the materials.

What are the factors affecting the poor adhesion of release films?

Release film is a type of film with a low surface energy coating on its surface, which can easily separate from pressure-sensitive adhesives and other sticky materials. The following are the main issues affecting the adhesion effect of release films:

What aspects should be noted in the processing of coated paper?

Base paper quality: The quality of the base paper directly affects the performance of the coated paper. It is important to choose base paper with high strength, good flatness, uniform fibers, and minimal impurities to ensure the physical properties and appearance quality of the paper after coating. For example, if the base paper has insufficient strength, it may easily crack during subsequent processing or use after coating.

What are the quality requirements for the processing of release films?

The surface of the release film should be flat and smooth, without wrinkles, waves, or unevenness. An uneven surface can affect its tightness during the lamination process, leading to issues such as bubbles or poor adhesion after lamination. For example, in the lamination of touch screens for electronic devices, if the surface of the release film is uneven, it can create gaps between the touch screen and the display module, affecting the display quality and touch sensitivity. During the processing, strict tension control and roller flatness checks should be implemented to ensure the flatness of the release film's surface.
