MULTI-LAYERED CONTAINER IMPROVED IN DELAMINATION

摘要

PROBLEM TO BE SOLVED: To provide a multi-layered container with layers of mutually different resins laminated without adhesive therebetween which is capable of preventing a delamination caused by fall or shocks and large in design versatility while not limited to a less uneven shape.

SOLUTION: In the multi-layered container, an outermost layer and an innermost layer mainly consist of a polyester resin, and at least one layer of intermediate layers mainly consists of a polyamide resin which is obtained by polymerizing a diamine component containing metha-xylilene diamine, and a dicarboxylic acid component consisting ofα,ω-straight chain aliphatic dicarboxylic acid and aromatic dicarboxylic acid with the glass transition temperature thereof in the range of 90-130°C.
