[PROBLEMS] To provide a heat-shrinkable polypropylene-based stretched film using a polypropylene-based resin composition having improved heat shrinkage, particularly low-temperature shrinkage. SOLUTION: The crystalline propylene-α-olefin random copolymer contains 50 to 100% and has an MFR of 0.5 to 100%. 10 g / 10 min, T 50 ≦ 125 ℃ (However, T 5 0 is Assuming that the total heat of fusion of the polypropylene-based resin composition determined by DSC is ΔHm, the heat shrinkage of the resin composition satisfying the temperature (° C.) at which the heat of fusion calculated from the low temperature side becomes 50% of ΔHm) Polypropylene-based stretched film. |
