A release liner is a pleastic release film which made of PE, PP or PET film as carrier, silicon coated on either one or two-sided releases options.
The film is uniform coated and very smooth and clean without wrinkles/tears/granules/bubbles/pinholes or other defects. This highly conformable product bonds well to most surfaces over a wide range of temperatures and release film is heavily used in consumer products worldwide.
Embossed Release Liner as a release material. Its surface can be 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.
