PE, the full name is Polyethylene, the simplest polymer organic compound, the most widely used polymer material in the world.
The surface can be coated with single or double-sided silicone oil. The products are widely used in protective film, self-adhesive products, foam tape, die-cutting, demoulding and other industries. It plays a very good role in isolation and protection.
PE release film as a base material. Its surface coating of ultra-thin layer of silicon from the type of material. The products are widely used in protective film, self-adhesive products, foam tape, die-cutting pressing, demoulding and other industries. It plays a very good isolation and protection role.
Advantages:
1.Easy peel off when remove the release film.
2.High residual adhesiveness rate(≥70%) to prevent the influence of silicon transfer on products.
3.Environmental Production technology of solvent and solvent-free products.
4.Environmentally Friendly. Can be recycling.
5.We have rich experience in product research and development to meet the various needs of customers.
