SURFACE PROTECTION FILM

摘要

Provided is a surface protection film which exerts appropriate adhesive properties even to an adherend having a rough surface and which exhibits excellent back surface slidability, blocking resistance, and reeling properties. Specifically, disclosed is a surface protection film which has a laminate structure comprising at least an adhesive layer and a back surface layer, wherein: the adhesive layer is mainly formed from a styrene-based elastomer; the back surface layer is mainly formed from a propylene-based resin containing 0.5 weight% to 10 weight% of a fluorine-containing compound having a polyfluoro-hydrocarbon group and a polyoxyethylene group, and has a 10-point average surface roughness (Rz) of 3µm or more; and the surface protection film has an initial adhesion strength of 1N/25mm or more in relation to a SUS304 plate, which was subjected to a #320 hair-line processing treatment, and has a reeling strength of 0.5N/25mm or less when the rolled-up film is being reeled.
