PET release film, also called PET silicone oil film, is coated with a layer of silicone oil on the surface of PET film, in order to reduce the adhesion of PET film surface and achieve the effect of separation. It can be divided into single side film and double side film. According to the detachment force, they can be divided into light detachment film, intermediate release film and re release film. The commonly used thickness: 0.012mm, 0.019mm, 0.025mm, 0.038mm, 0.05mm, 0.075mm, 0.1mm, 0.125mm, 0.188mm, PET film manufacturers are equipped with large strips, slicing machines, according to your specifications in separate sections. Jin PET film has been widely packaging, printing, screen printing, printing, nameplate, membrane switch, flexible circuit, insulation products, circuit board, laser anti-counterfeit, laminating, electronic, material sealing film, reflective material, waterproof material, medicine (plaster paper), toilet paper, adhesive products, die cutting processing industries.
The method of separating film
PET film: * heat transfer film, peeling film, isolation film, synovial membrane, paper, silicone oil film, anti mucous membrane, silicone oil release paper, silicone oil paper, mask film, PET film, also called PET transfer film. It is mainly used as vacuum aluminum plating carrier, that is, the PET film is placed in the vacuum aluminum plating machine after aluminum plating, glue and paper composite, and then peel off the PET film, aluminum molecular layer through the adhesive role will be transferred to the cardboard surface, forming the so-called aluminum cardboard. The production process of aluminium plated cardboard is: PET base film, parting layer, filter layer, aluminizing layer, coating layer, and transfer to paperboard.
In order to improve the surface properties of PET film and improve the adaptability of printing and the bonding force of vacuum aluminized layer, corona treatment is usually used to improve the surface tension of the film. However, the corona method has the problems of aging, especially in the environment of high temperature and high humidity, the film tension after corona treatment is easy to be attenuated. However, there is no such problem in chemical coating process, so it is favored by printing industry and aluminum plating industry.
At present, China has developed a series of products: PET chemical coating such as water soluble polymer coating can improve the surface tension of PET film; with acrylic emulsion coating, can improve the printing adaptability (can use water soluble ink); the aqueous polyurethane coating, can strengthen the binding force of aluminized layer and PET membrane. And can increase the thickness of aluminum layer. In addition, the high resistance diaphragm and antistatic film can also be prepared by coating method.
