<P>PROBLEM TO BE SOLVED: To provide an injection molding which has an excellent balance in impact strength and tensile elongation at break. <P>SOLUTION: The injection molding is composed of a polyethylene-based resin composition comprising: 18 to 50 mass% of aliphatic polyester (A); 40 to 77 mass% of the following component (B); and 3 to 15 mass% of a compatibilizer (C) (wherein, the total content of the component (A), the component (B) and the component (C) is 100 mass%). The component (B) denotes an ethylene-α-olefin copolymer in which density is 905 to 950 kg/m<SP POS="POST">3</SP>, a melt flow rate is 0.5 to 20 g/10 min, and the activation energy (Ea) of a flow is 55 to 100 kJ/mol. <P>COPYRIGHT: (C)2012,JPO&INPIT |
