PROBLEM TO BE SOLVED: To provide a heat shrinkable laminated polyolefin film in which no deterioration in transparency and gloss takes place even when a recycled material such as film pieces generated in a production process, nonconforming films, etc., is used for the intermediate layer of the film in a heat shrinkable laminated film consisting of polyethylene surface layers and a polypropylene intermediate layer. SOLUTION: Surface layers are made from linear low density polyethylene (A) of 0.900-0.930g/cm<3> density at 25 deg.C, and an intermediate layer is made from 50-90 pts.wt. of crystalline polypropylene (B), 10-50 pts.wt. of syndiotactic polypropylene (C) [the total of (B) and (C) is 100 pts.wt.], and 0-40 pts.wt. of linear low density polyethylene (A). The thickness of the intermediate layer is 30% or more of the total, the thickness of the surface layers is at least 1μm, and a film is biaxially stretched at least two times. |
