Analysis of the production method of PET release film

The PET release film is coated with a layer of silicone oil on the surface of the PET film to reduce the adhesion of the PET film surface and achieve the release effect. Can be divided into single-sided release film and double-sided release film. According to the release force, it can be divided into a light release film, a medium release film, and a heavy release film. Commonly used thicknesses are: 0.012mm, 0.019mm, 0.025mm, 0.038mm, 0.05mm, 0.075mm, 0.1mm, 0.125mm, 0.188mm. PET release film manufacturers are equipped with large slitting, slicing machines, press Divide and slice according to your specifications. PET release film has been widely used for packaging, printing, silk screen, pad printing, nameplate, membrane switch, flexible circuit, insulation products, circuit board, laser anti-counterfeiting, lamination, electronic, sealing material film, reflective material, waterproof Materials, medicine (paste paper), sanitary paper, adhesive products, die-cutting processing and other industrial fields.

PET release film, also known as thermal transfer film, release film, barrier film, slip film, Tianna paper, silicone oil film, anti-adhesive film, silicone oil release paper, silicone oil paper, mask film, PET release film is also called PET Transfer film. It is mainly used as a vacuum aluminum plating carrier. After the PET film is placed in a vacuum aluminum plating machine, the rubber film is laminated with the paper, and then the PET film is peeled off, and the aluminum molecular layer is transferred to the surface of the paperboard by the adhesive action. A so-called aluminized cardboard is formed. The production process of the aluminized cardboard is: PET base film → release layer → color layer → aluminized layer → glue layer → transfer to cardboard.
