发明名称 SURFACE PROTECTIVE FILM
摘要 Provided is a surface protective film that not only maintains its adhesion for an adherend but also shows a small change over time in rewinding force even when stored in a roll shape. The surface protective film of the present invention includes: a back surface layer; a base material layer; and a pressure-sensitive adhesive layer in the stated order, in which: the surface of the back surface layer has a ten-point average surface roughness Rz of 1.0 or more; a rewinding force A after storage at 23° C. is 1.0 N/20 mm or less; and a ratio B/A of a rewinding force B after storage at 50° C. to the rewinding force A after the storage at 23° C. is 1.0 to 2.0.
