<p><P>PROBLEM TO BE SOLVED: To provide a plastic molding which has a feel of frosting similar to that of a molding made of glass and also has excellent low temperature impact strength and moldability. <P>SOLUTION: Disclosed is a multi-layer blown molding formed by a stacked body at least comprising a surface layer (A) and an internal layer (B). The surface layer (A) is composed of polyethylene in which a melt flow rate (HLMFR) at a temperature of 190°C and a load of 21.6 kg is 3.0 to 15 g/10 min, a melt flow rate (MFR) at a temperature of 190°C and a load of 2.16 kg is 0.02 to 0.1 g/10 min and density is 0.935 to 0.964 g/cm<SP>3</SP>, and the internal layer (B) is composed of polyethylene in which a melt flow rate (HLMFR) is >15 to 680 g/10 min, a melt flow rate (MFR) is 0.1 to 7.0 g/min and density is 0.935 to 0.964 g/cm<SP>3</SP>. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
