PET silicone oil film, also known as PET release film, is a layer of silicone oil applied to the surface of PET film to reduce its adhesion and achieve release effect. The conventional thickness ranges from 25um to 150um. There are two types of products: cold and hot tearing and smooth and matte surface. After anti-static and scratch resistant treatment, the product has good adsorption and adhesion. It can be divided into single-sided release film and double-sided release film; According to the release force, it can be divided into light release membrane, medium release membrane, and heavy release membrane.

Application scope: PET release film has been widely used in industries such as packaging, printing, circuit boards, laser anti-counterfeiting, lamination, electronics, sealing materials, reflective materials, waterproof materials, pharmaceuticals (plaster paper), sanitary paper, adhesive products, die cutting and punching processing.

Common characteristics with silicone oil film:

① Both are based on PET, and the product surface is coated with 0.2um-0.6um release substance;

② The surface is flat, smooth, and evenly coated;

③ No creases or tears;

④ No defects such as particles, bubbles, pinholes, etc;

⑤ Small thickness tolerance and high transparency;

⑥ Low thermal shrinkage and good flexibility.

If we get these two materials, how should we distinguish them? Actually, from the surface, there is no difference between the fluorine release film and the silicone oil film, and the appearance is almost difficult to distinguish. Therefore, online coating believes that in order to understand the differences between the two materials, we can analyze them through the following points:

① The fluorine release film will not react with the silicone adhesive surface, and the release force is stable; The silicone oil film will react and cannot peel off;

② Differentiation in price:Fluoride release film price is relatively high, while the silicone oil film is relatively low;

③ MY-2G is used for the release force test of fluorine film, and TESA7475 is used for the release force test of silicone oil film (specific testing steps can refer to the standards provided by the manufacturer);

       ④ In the selection of die-cutting materials: generally, silicone tape is paired with fluorine film, while acrylic tape is paired with silicone oil film. Of course, the materials selected for different products may also vary.
