PROBLEM TO BE SOLVED: To provide a shrink film which suppresses occurrence of natural shrinkage, has high rigidity, is excellent in thermal shrinkability, and has thermal shrinkability in an MD direction.SOLUTION: There is provided a shrink film which has thermal shrinkability in an MD direction, and has a five-layer structure of surface layer/A layer/B layer/A layer/surface layer or surface layer/B layer/A layer/B layer/surface layer, where the surface layer is a layer containing an amorphous cyclic olefin-based polymer or a polypropylene-based resin as a main component, the A layer is a layer containing 10-49 wt.% of a polypropylene-based elastomer and 5-90 wt.% of an amorphous cyclic olefin-based polymer, and the B layer is a layer containing a polypropylene-based elastomer as a main component.SELECTED DRAWING: None |
