A surface protection film comprises at least a surface layer (A) and an adhesive layer (X), and is characterised in that the surface layer (A) is formed from a polyolefin resin and the adhesive layer (X) is formed from a composition comprising: 0-50 mass% of an a-olefin(co)polymer (X-1), having a melting point which is either unobserved or is less than 50°C and the main component of which is an a-olefin having 3 or more carbon atoms; 0.5-50 mass% of at least one olefin(co)polymer (X-2) which is a propylene (co)polymer (X-2a) having a melting point within the range of 50-140°C and/or an ethylene(co)polymer (X-2b) having a melting point within the range of 50-140°C inclusive; 10-98 mass% of a styrene-based elastomer (X-3); and 0-50 mass% of an oligomer (X-4). Therein, the sum of (X-1), (X-2), (X-3) and (X-4) is 100 mass%. |
