Science Knowledge About Release Film
Types and uses of release film
Release film is a type of release material, which refers to the anti adhesion material made by applying anti adhesion agent on the substrate. It is an important material in the production of pressure sensitive adhesive products. Pressure sensitive adhesive products such as pressure sensitive labels, adhesive paper, double-sided pressure sensitive adhesive, adhesive wallpapers, and other adhesive sheets are all composed of pressure sensitive adhesives, substrates, and release materials.
Usually, in order to increase the release force of plastic films, plasma treatment, fluorine coating, or silicon release agent are applied to the surface of the film material, such as PET, PE, OPP, etc; It can exhibit extremely light and stable release force for various organic pressure sensitive adhesives. Depending on the required release force of the release film and the viscosity of the isolation product adhesive, the release force should be adjusted accordingly to achieve an extremely light and stable release force during peeling. Below is a brief introduction to several release membranes.
Blue PET Release Film
The blue PET release film is made by using the blue PET film as the substrate, coating the release material on its surface and conducting anti-static treatment (usually anti-static treatment on the release surface); The surface of the film is flat and smooth, without defects such as wrinkles, tears, particles, bubbles, pinholes, etc; This product has advantages such as excellent release stability, good release layer adhesion, small thickness tolerance, low heat shrinkage rate, and good flexibility;
Usage: Widely used in industries such as backlight die-cutting, digital product die-cutting, mobile phone die-cutting, adhesive products, etc.
Transparent Silicon Release Film
Transparent double silicon release film, application range: electronics, automotive foam, printing, etc. Its usage range is mostly combined with adhesive, transparent double silicon release film, especially tape products. Widely used in the processing of various products, such as electronic power and IT display screens. Mobile phones, LCD/PDA, medical devices, home appliance manufacturing, anti-counterfeiting materials, semiconductors, automobiles, nameplates, ceramic chip manufacturing, tape production, and die-cutting industries.
Red Release membrane
Usage: Electronic materials, tape, etc.
Product characteristics: Bright and bright colors, good heat resistance
