The polyva film teaches you how to use the release film correctly. Source: Protective film factory direct sales Release time: 2019-12-13 Hits: 4253 Silicon release film: Generally used with acrylic glue, it can play a good role in isolating glue molecules Penetrating effect, can easily peel off the double-sided tape from the release film. Fluorine release film: Use with silica gel. The reason is that silica gel and silicon release film are prone to chemical reactions, and fluorine can effectively isolate silica gel molecules. 1. The industry collocation standard 3:1 is the lowest release force collocation for double-sided tape mother roll production, and 5:1 is the lowest die-cut product release force collocation, but many people have misunderstood the meaning, its release film collocation The ratio is based on the release force generated by each type of double-sided tape and the release film, not the general standard release force. 2. When the single die-cut product single-piece glue (or island glue) is less than 10 mm, the release force ratio of the release film should be increased. 3. The function of the release film is to isolate the molecules of the double-sided tape from penetrating and generate release force, but the thicker the double-sided tape layer, the greater the fluidity of the adhesive, and the stability of the release force will be relatively lower. The ratio of release film should be increased. 4. Without affecting the customer's use, try our best to increase the matching ratio of the release film to reduce the risk of anti-release. The main functions of the release film are isolation, filling, protection, and easy peeling. For punching, you have to choose a release film for punching, and the hardness is enough.
