Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a surface protection film which has a superior initial tackiness to a material to be adhered and a less adhesion-acceleration with time, therefore the adhesive of which does not contaminate the material to be adhered. SOLUTION: The surface protection film is prepared by a laminated base material layer of thermoplastic resin and an adhesive layer, and a resin constituting the adhesive layer of at least one type, selected from a polyisoprene, polyisobutylene and butyl rubber having a weight average molecular weight of 10,000-45,000, of 5-100 weight parts against 100 weight parts of polyolefin- based resin is combined. |
