(57) [Summary] (with correction) [PROBLEMS] To provide a polyolefin resin composition having an excellent balance of softness, stress whitening resistance, haze, scratch resistance and low-temperature impact resistance. SOLUTION: 100 parts by weight of a polyolefin resin is composed of a polymer block A mainly composed of a vinyl aromatic compound monomer unit and a hydrogenated polymer block B, and 80% or more of hydrogenated hydrogen is used. In the added block copolymer, (a) a hydrogenated block copolymer having an average vinyl bond amount in a range of Va 1 to 100 parts by weight Va = (Xa-Ya) * Z + Ya [Z = (butadiene monomer) Amount) / (amount of butadiene monomer + amount of isoprene monomer), 62 ≦ Xa <99, 35 ≦ Ya <99], and (b) hydrogenated blocks having an average vinyl bond amount in the range of Vb. Polymer 1 to 100 parts by weight Vb = (Xb-Y b) * Z + Yb [10 ≦ Xb <62, 1 ≦ Yb <35] The resin composition which mix | blends. |
