Do you know what material the release film is?

The release film is to apply the silicone release agent on the surface of the environmentally friendly PET and E OPP films, 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 for the release film, and the stickiness of the needles to isolate the product is different. The force is adjusted accordingly to achieve an extremely light and stable release force during peeling.

Release film classification: According to different substrates, it can be divided into PE release film, PET release film, OPP release film, and composite release film (that is, the substrate is composed of two or more materials ).

According to the release force, it can be divided into light release film, medium release film, and heavy release film. 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.

According to the Si content, it can be divided into silicon-containing release film and silicon-free release film. 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, hygiene 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 tape.

Sunscreen isolation film (HDPE silver coating film): Waterproof membrane for sun protection and cooling.

Enhanced aluminized substrate BOPP enhanced (BOPET): Improve the adhesion of the aluminized layer and make it resistant to 100°C evaporation cook.

According to 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. Color release film plays a role in identification. The coating layer is sandwiched between two layers of film, which can protect the coating layer and effectively avoid the influence of the coating layer on the release agent layer. The release film layer is an indispensable structural layer of the composite film, which plays a protective role before the composite film is used. During metal plating, metal atomization magnetron or vacuum plating or printing is applied to the substrate by heating the metal to form an electroplating layer. Pressure sensitive adhesive, transparent and colorless clear adhesive, insoluble in water, has strong adhesion to glass, antistatic silicone release coating film: 100 organopolysiloxane, 0.05 conductive polymer resin, 0.05 05 silane coupling agent, 5 organohydrogen polysiloxane, 50PPM platinum chelate catalyst, it is a coating composition. The coating contains curable silicone, the coating contains solvent-based silicone and solvent-free silicone as the main components, and reactive heavy peeling regulator. Release agent (F, Cr).
