PROBLEM TO BE SOLVED: To provide a polypropylene-based resin composition for a stretched film, which is excellent in rigidity, heat shrinkage, and stretchability while maintaining transparency and anti-blocking property at a practical level, and production of the resin composition. Methods and stretched films are provided. SOLUTION: The intrinsic viscosity [η] A is in a certain range, A propylene polymer A having a melting point Tm A in a certain range and a content in a certain range, an intrinsic viscosity [η] B in a certain range, and a melting point Tm B in a certain range; Contains a propylene-based polymer B in a certain range, The ratio of the melting point Tm A of the propylene-based polymer A to the melting point Tm B of the propylene-based polymer B is within a certain range, and the intrinsic viscosity [η] A of the propylene-based polymer A and the propylene-based polymer B A polypropylene resin composition for a stretched film, wherein the intrinsic viscosity [η] B ratio is within a certain range and the melt flow rate is within a certain range, a method for producing the resin composition, and a stretched film. |
