Document Type and Number:
Japanese Patent JP3147031
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a seamless can and a laminated body for manufacturing the can, which is excellent in forming characteristics, and suppress, to the utmost, low molecular weight constituent, which inevitably presents in polyester, from migrating into the content for suppressing turbidity during high temperature treatment and storage in an extended period.
SOLUTION: A laminated body for can manufacture comprises a metal base and a thermoplastic polyester layer provided thereon. The thermoplastic polyester layer is formed of extruded coat such as copolymer polyester or blended polyester, containing an ethylene terephthtalate unit so that the amount of terephthalic acid component is 5-99 mol% of overall basic carboxylic acid component, and containing an ethylene naphthalate unit so that the amount of naphthalene dicarboxylic acid component is 1-95 mol% of overall basic carboxylic acid component.
