Release material is a material with release (anti-adhesive) properties formed by coating a layer of special release agent on the surface of the substrate, which is mainly used to prevent unwanted adhesion of adhesive substances to their contact surfaces. This material plays a vital role in industrial production, especially in pressure-sensitive adhesive products, adhesive labels, electronics, medical, packaging, printing, screen printing, pad printing, nameplates, membrane switches, PCB manufacturing, insulating products, circuit boards, laser anti-counterfeiting, laminating process, reflective materials, waterproof materials, medicine and health, adhesive products processing, and many other fields have a wide range of applications.
Release material mainly includes two types of release paper and release film:
- Release paper: paper as a substrate, through the coating of silicone release agent or other types of release agent to form an anti-adhesive layer. Release paper has a certain degree of mechanical strength, temperature resistance and good printing suitability, suitable for the cost, environmental protection and writeability of the higher requirements of the application scenarios.
- Release film: Plastic film (such as PET, PE, OPP, etc.) as the substrate, coated with silicone release agent or fluorine release agent, forming transparent or translucent release film. With its excellent optical properties, high temperature resistance, low shrinkage, good dimensional stability and good electrical insulation properties, release film is suitable for high-end applications with more demanding material properties.
