<p><P>PROBLEM TO BE SOLVED: To provide a multilayer container which makes a peeling due to fall and shock hardly occur while enabling a degree of freedom for design to enhance without limiting to the shape of less irregularities, and is excellent in a resistance against interlayer peeling. <P>SOLUTION: The multilayer container comprises a resin A of a polyethylene terephthalate constituting an utmost external and internal layer, and a resin B constituting an intermediate layer provided between the utmost external layer and the utmost internal layer. The resin A has an intrinsic viscosity of 0.55 to 1.50. At 280°C and shear rate of 1000/s, the melt viscosity ratio for the resin A and resin B äthe resin A (Pas)/the resin B (Pas)} ranges within 0.5 to 3.0, thereby improving the resistance against interlayer peeling. <P>COPYRIGHT: (C)2004,JPO</p> |
