How Much Do You Know about Release Film?

Release film refers to a thin film with distinguishable surface properties. After contact with a specific material under limited conditions, the release film does not have viscosity or has a slight viscosity. Usually, in order to increase the release force of plastic film, plasma treatment, fluorine coating, or silicon release agent is applied to the surface of the film material, such as PET, PE, OPP, etc.

Different organic pressure-sensitive adhesives, such as hot melt adhesive, acrylic adhesive, and rubber based pressure-sensitive adhesives, can exhibit extremely light and stable release force. According to different required release film release forces, the viscosity of the isolation product adhesive varies, and the release force is adjusted accordingly to achieve extremely light and stable release force during peeling.

Release film is widely used in the processing of various products, such as electronic power and IT display screens. Mobile phone, LCD/PDA, medical, home appliance manufacturing, anti-counterfeiting materials, semiconductors, automobiles, nameplates, ceramic wafer manufacturing, tape production, and die-cutting industries. The application fields of release films made of different materials are also different.

PET (stretch polyester) single and double-sided release film: double-sided tape, advertising printing material backing protection, reflective material backing protection, waterproofing membrane, etc;

BOPP release film: used for sealing tape, silent tape;

PET fluoroplastic release film: applied to silicone based adhesives; The PET green high-temperature tape coated with PET fluoroplastic release film has a good release effect; Die cutting and punching purposes.
