Title:
二軸延伸ブローボトル
Document Type and Number:
Japanese Patent JP5019733
Kind Code:
B2
Abstract:

To provide a biaxially stretched blow-molded bottle excellent in impact delamination resistance, transparency, gas-barrier properties, pressure resistance and pressure resistance uniformity.

The material of a biaxially stretched blow-molded bottle is produced by disposing an ethylene-vinyl alcohol copolymer including a structural unit (1) as an intermediate layer and arranging a thermoplastic polyester resin on both outer layers. The ethylene-vinyl alcohol copolymer (EVOH) is preferably obtained by copolymerizing 3,4-diacyloxy-1-butene, vinyl ester-based monomer and ethylene, and then saponifying the obtained copolymer. In the structural unit (1), X is an optional bond chain excluding an ether bond; R1 to R4 are each independently an optional substituent; and (n) is 0 or 1.
