Do you know the differences between fluoride release film and coating film? If you don't know, follow us to learn more!

1、 Coating film:

In order to improve the surface performance of PET film, improve the adaptability of printing, and enhance the adhesion of vacuum aluminum coating, corona treatment is usually used to increase the surface tension of the film. However, the corona method has issues with timeliness, especially in high temperature and humidity environments where the film tension after corona treatment is easily attenuated. However, the chemical coating method does not have such a problem, so it is favored by the printing and aluminum plating industries.

At present, a series of PET chemical coating products have been developed in China: such as water-soluble polymer coating, which can improve the surface tension of PET films; Coating with acrylate lotion can improve the adaptability of printing; Applying polyurethane aqueous solution coating can enhance the adhesion between the aluminum coating and the PET substrate film, and increase the thickness of the aluminum coating. In addition, the coating method can also be used to produce high resistance membranes and anti-static films.

2、 Fluoride release film:

The PET fluorine release film is made of polyethylene terephthalate (PET) as the substrate, and the product surface is coated with 0.2um~0.6um fluorine release substance. The surface of the film is flat and smooth, evenly coated, and free from defects such as wrinkles, tears, particles, bubbles, and pinholes. This product has advantages such as excellent physical and mechanical properties, small thickness tolerance, high transparency, low thermal shrinkage, and good flexibility.

It has been widely used in industries such as adhesive products, die-cutting and stamping processing, and electronic and electrical manufacturing, mainly for release silicone.

The thickness is 0.05MM, 0.075MM, 0.1MM, the width is 520MM and 1040MM, and the length is 500M and 3000M. There are two colors available: transparent and white.
