PROBLEM TO BE SOLVED: To provide a polyolefin resin composition that has rigidity, heat resistance, transparency, impact resistance and thermoformability possessed by polypropylene at a high level in a well-balanced combination. SOLUTION: A polyolefin resin composition comprises (A) 50-85 wt.% crystalline polypropylene which may includeα-olefin as a comonomer, wherein the component A has a) MFR of 0.1-50 g/10 min, and b) a main melting peak temperature on a DSC curve of not less than 160 deg.C, a crystallization initiation temperature of not less than 130 deg.C and a crystallization peak temperature of not less than 125 deg.C, (B) 15-50 wt.% copolymer of ethylene as a main component andα-olefin, wherein the component B has c) a density of 0.93-0.88 g/cm3, d) MFR of 0.1-50 g/10 min and satisfies e) a relationship of H/W>=2.33×10-3( deg.C-1) when a maximum peak temperature on an elution curve obtained by temperature rising elution fractionation is 15-85 deg.C, H represents the height of the peak (a unit: fraction) and W represents the width of the peak at one third of the height H (a unit: deg.C), and (C) 0.03-2 wt.% nucleating agent. |
