What is a release film?
The release film is to coat the silicone release agent on the surface of the environmentally friendly PET, PE, OPP film, so that it can show extremely light and stable release force for various organic pressure-sensitive adhesives. Different organic pressure-sensitive adhesives, such as hot-melt adhesives, acrylic adhesives and pressure-sensitive adhesives of rubber systems, etc., require different release forces of the release film. The force is adjusted accordingly to achieve an extremely light and stable release force during peeling.
The release film classification can be divided into different substrates: PE release film, PET release film, OPP release film, and composite release film (that is, the substrate is composed of two or more materials) Wait.
According to the release force, it can be divided into: light release release film, medium release release film, and heavy release release film.
There are various types of release paper according to product performance and use. If you don’t know how to choose the right product, you don’t know the use and price, you can choose the online consultation website for customer service consultation or direct telephone consultation, and we will help you recommend suitable products for you.
According to the color, it can be divided into: red release film, yellow release film, green release film, blue release film and other PET release films of various colors.
According to surface treatment, it can be divided into: single-sided release film, double-sided release film, silicon-free release film, fluoroplastic release film, single-sided corona, double-sided corona, frosted release film, matte release film film etc.
Single-sided release film: HDPE (low pressure polyethylene) release film: used for waterproofing membranes such as sealing tapes.
LDPE (high pressure polyethylene) release film: mechanical product packaging, hot melt adhesive packaging, sanitary care products (diapers), anti-corrosion coils, etc.
BOPP (stretched polypropylene) release film: used for sealing tape, silent tape, etc.
PET (Stretched Polyester) Release Film: Adhesive Protection, etc. Double Sided Release Film: Red/Green Polyolefin (PE) Double Sided Release Film: For Foam Tape Transparent PET Double Sided Release Film: Double Sided Adhesive sunscreen isolation film (HDPE silver coating film): Enhanced aluminized substrate for sunscreen and cooling of waterproof rolls
According to the material and use, it can be divided into: silicone oil film/release film-polyester film (PET), polyester film, pre-coating film, light diffusing film, color inkjet film (computer film), special printing film for the electronics industry, frosted Film, drawing film, white polyester film, black polyester film, PET/polyester film/PET Mylar.
