PET release film is a very common material, which is a kind of coating silicone oil or other substances on the surface of PET film, so that the surface of the film has a release force, so as to achieve a variety of functions.
There are thousands of types of PET release film, and it is widely used in life.
Unwinding section
After passing through this device, the base film enters the coating head, where the surface of the film is coated with a layer of silicone oil.
Hot airbox controller
The film coated with silicone oil needs to be baked by a hot air box to volatilize the solvent in the silicone oil.
Winding section
After the film has been baked at high temperatures, the solvent has evaporated, and the quality inspection and winding are carried out here.
Because it is a double-dumb double-silicon release film, silicone oil must be coated on both sides. The same process is repeated, and a qualified roll of double-dumb double-silicon release film is produced.
