SURFACE PROTECTIVE FILM AND PROPYLENE COPOLYMER COMPOSITION FOR SURFACE PROTECTIVE FILMS

摘要

[Solution] A surface protective film which has, as a surface layer, a film that is formed from a propylene copolymer composition that contains from 75% by weight to 97% by weight (inclusive) of a specific propylene-ethylene block copolymer (A) and from 3% by weight to 25% by weight (inclusive) of a specific ethylene elastomer (B) (provided that the total of the components (A) and (B) is 100% by weight); and the propylene copolymer composition which is suitable for the production of the surface protective film. [Effect] The present invention is able to provide a surface protective film that has less fish eyes, thereby causing less damage to an object to which the surface protective film is bonded, and that has sufficient transparency and excellent functionality as a surface protective film. This surface protective film exhibits excellent blocking resistance even in cases where the surface protective film is wound into a roll and stored without using a release film, and has a surface layer that exhibits excellent pull-out properties when pulled out of the film roll for use.
