<P>PROBLEM TO BE SOLVED: To provide a polyethylene resin composition capable of giving a foam with a high expansion ratio, superior compression durability, and superior secondary processability. <P>SOLUTION: The polyethylene resin composition consists of 95-30 wt.% of an ethylene-α-olefin copolymer (a) and 5-70 wt.% of a high-pressure process low density polyethylene (b). In the ethylene-α-olefin copolymer: a melt flow rate measured at 190°C with a load 2.16 kg according to the ASTM 1238 is ≥0.1 g/10min and <50 g/10min, a melt tension at 160°C is ≥40 mN, strain hardening property is provided, and density based on the JIS K6760 is 920-950 kg/m<SP POS="POST">3</SP>. <P>COPYRIGHT: (C)2013,JPO&INPIT |
