Abstract
A polyolefin resin composition comprises a component A consisting of polypropylene or a propylene-ethylene block copolymer whose MFR is greater than 16 (g/10 minutes); a component B consisting of an ethylene based rubber; and a component D compatible with the component B. A ratio of summation of the propylene-ethylene copolymer part in the component A, the component B, and the component D to summation of the components A, B, and D is 25 wt. % or more and 45 wt. % or less. Further, a ratio of the blend quantity of the component D to summation of the blend quantities of the components B and D is less than 0.8. In this manner, the bending elastic modulus and the tensile breaking extension are included in a desired region, while the tensile breaking extension is improved.
