Silicone Coated Polyester Release Film

DN508 silicone coated polyester release films are manufactured using a special coating process where silicone oil is coated directly onto the film surface, ensuring an excellent uniformity and low release force.

This kind of BOPET release film is widely used as a one side film coated release film, two sided coated release film, antistatic release film, hard coat release film and other release film types. These films are also widely used as transparent trademark films, protection films, and ceramic resin release films in the electronics industry, and separator films in electronics.
