Fluoride release film also called fluoroplastic film or ETFE, it is mainly used to isolate sticky materials, such as silicon tape, PI tape, etc. It plays a role in protecting the adhesive from contamination and deterioration during production, storage, or transportation. Currently, the most widely used carriers are tape or adhesive products. So what factors will affect the quality of fluoride release membranes?

1、 Smoothness

The first factor affecting fluorine release film is smoothness, because if the surface smoothness of the paper is not enough, it will affect the printing gloss and dot reduction. Therefore, only by ensuring that the surface of fluorine release film has good smoothness can it have a flat appearance and improve the printing effect on its surface. Moreover, a smooth surface can also save more on the use of silicone oil.

2、 Physical strength

Physical strength is the second important factor affecting fluorine release membranes. Because high-quality fluorine release films require high internal strength to have good resistance to external tensile, wet, and tear forces, ensuring that the paper is not damaged. Therefore, their use as packaging for food and medicine can provide effective protection.

3、 Permeability resistance

      Due to professional waterproofing and oil resistance are required, so permeability is a very important factor affecting its quality. Only with strong permeability can it be better resistant to oil and various solvents. Therefore, it can avoid excessive silicone oil penetration when coating its surface, which not only saves raw materials but also ensures better peeling force.
