ramine which is superior in chip resistance - to diaphragm container and its manufacturing method

摘要

A laminated draw-formed container obtained by draw-forming a laminated material of a metal plate on which a resin film is laminated into a cup with bottom, wherein the resin film comprises a polyester composition which contains a polyethylene terephthalate component as a chief component and further contains a polyethylene isophthalate component and a polybutylene terephthalate component, the resin film having a density of from 1.32 to 1.39 g/cc at any part of the container and further having, on the upper part of the container, a trans ratio of ethylene glycol residue of from 0.1 to 1.5 as found by the ATR method, as well as a process for producing the container. The draw-formed container exhibits excellent shock resistance irrespective of the passage of time, and particularly dent resistance and barrier property against corrosive components, as well as intimate adhesion to the metal substrate.
