(57) [Problem] To provide a stretch packaging film excellent in indentation recovery property, heat sealing property, cold resistance, cutting property and transparency. SOLUTION: The polypropylene resin 50 is composed of both surface layers (S layers) made of a polyolefin resin having a melting point of 60 to 100 ° C and at least one heat-resistant layer (H layer), and the H layer has a melting point of 150 ° C or more. A stretch packaging film comprising about 95% by weight and 5 to 50% by weight of a hydrogenated product of a specific vinyl aromatic compound block-conjugated diene compound block copolymer. |
