PROBLEM TO BE SOLVED: To provide a heat shrinkable polyolefine film a heat shrinkage factor of which is large at a high temperature≥80°C, keeping characteristics suppressing a natural shrinkage factor, without generating an appearance degradation in applications accompanying a retort disinfection treatment and having a low specific gravity. SOLUTION: The heat shrinkable polyolefine film is comprised of a polypropylene resin, a petroleum resin and a cyclic polyolefine, and has a heat shrinkage factor in the main stretching direction of≥50% at 95°C×10 sec and satisfies a specific haze characteristics, a specific gravity and a specific natural shrinkage factor.
