THERMALLY SHRINKABLE LAMINATED FILM |
摘要 |
Disclosed is a thermally shrinkable laminated film which is produced by laminating an intermediate layer comprising a block copolymer resin composition containing a specific block copolymer directly between a front layer and a back layer each comprising a polyester resin, and which has good interlayer adhesion strength. Specifically disclosed is a thermally shrinkable laminated film which is produced by stretching a three-layered laminated sheet along at least one axis so that the interlayer adhesion strength becomes 0.6 N/15 mm or more, wherein the three-layered laminated sheet has an intermediate layer and a front layer and a back layer, the intermediate layer comprises a resin composition comprising two types of block copolymers each having a specific structure and a specific composition at a predetermined mass ratio, and each of the front layer and the back layer comprises a polyester resin. |
