Types and characteristics of surface protection film
- Feb 03, 2019 -

Surface protection film can be mainly divided into two major categories, namely, rubber film and self-adhesive film. Among them, a type of the adhesive film adhesive is a solvent type rubber adhesive, a solvent type acrylic adhesive, an aqueous acrylic adhesive, and a silicone adhesive. Among them, water-based acrylic adhesives are the most commonly used products, which can easily adjust the adhesion, and have good transparency and weather resistance.

The self-adhesive surface protective film products are currently produced by a co-extrusion process, and the self-adhesive layer is generally EVA, ultra-low density polyethylene or polyolefin plastomer resin, and this structure has gradually become a market. Mainstream, because it has more advantages than coated film, such as no residual glue, providing stable adhesion, reducing user costs and creating higher profits for protective film manufacturers.

Further, depending on the gel system used for the surface protective film, it can be classified into a rubber system and an acrylate system. Among them, the rubber protective film features: soft, can reach the final viscosity quickly; molecular mobility is good; relatively easy to tear.
