<p><P>PROBLEM TO BE SOLVED: To provide a multilayered structure object which has a superior secondary-processability for a deep-drawing shaping and the like while causing less odor and coloring due to the degradation of a resin at its manufacture and secondary processing and being excellent in its transparency and gas-barrier performance, and a container formed by using them. <P>SOLUTION: The gas-barrier multilayered structure object and the multilayered container formed by using the same object are composed of a polyamide resin which is obtained by the polycondensation of the principal components of a metaxylilene diamine andα,ω-straight chain aliphatic dicarboxylic acid. The object and the container are formed by laminating a gas-barrier layer of at least one layer, containing a crystalline polyamide resin whose semi-crystallization time by a constant-temperature crystallization in a de-polarizing luminous method has a specific range, and also a thermoplastic resin layer of at least one layer. <P>COPYRIGHT: (C)2004,JPO</p> |
