<p><P>PROBLEM TO BE SOLVED: To provide a multilayer blow pack whose moldability is satisfactory with an improved heatproof characteristic, container surface luster and clarity. <P>SOLUTION: The inside layer, the outside layer and the intermediate layer of this multilayer blow pack is made of an ethylene polymer. At least the intermediate layer is structured using a resin compound mainly using ethyleneα- olefin copolymer polymerized by a metallocene catalyst, and the ratio of the thickness of the inside and outside layers to that of the intermediate layer is between 20:80 and 70:30. <P>COPYRIGHT: (C)2003,JPO</p> |
