摘要： The present invention provides a surface protection film that has moderate adhesive properties for bonding to adherend bodies with a rough surface, has a rear surface with good slipping properties, and also has blocking resistance and good unwinding properties. The surface protection film according to the present invention has a laminated structure formed at least of an adhesive layer and a back layer, wherein the adhesive layer is formed mainly of a styrene-based elastomer while the back layer is formed mainly of a propylene-based resin containing 0.5 wt% to 10 wt% of a fluorine-containing compound having a polyfluorohydrocarbon group and a polyoxy ethylene group, the back layer having a surface roughness of 3 µm or more in terms of ten-point average roughness (Rz), an initial adhesion strength of 1 N/25 mm or more to a #320 hair-line-finished SUS 304 plate, and an unwinding force of 0.5 N/25 mm or less for winding off a film wound up in a roll.

摘要： The present invention is intended to provide a surface protection film that has moderate adhesive properties for adherend bodies with a rough surface, has a rear surface with good slipping properties, and also has blocking resistance and good unwinding properties (decreased unwinding tension to enable easy, high-speed sticking of the film to an adherend without causing creases or flaws). The surface protection film according to the present invention has a three-layered composite structure including an adhesive layer, an interlayer, and a back layer, wherein the adhesive layer is formed of 35 to 90 wt% of a linear low density polyethylene, 5 to 50 wt% of a styrene-based elastomer, and 15 wt% or less of a tackifier, the interlayer formed mainly of a propylene-based resin, and the back layer formed mainly of the same propylene-based resin as that constituting the interlayer and/or a different propylene-based resin therefrom, and also wherein the back layer has a surface roughness of 3 µm or more in terms of ten-point average roughness (Rz).
