ABSTRACT:
Disclosed is a plastic multilayer vessel having a laminate structure comprising an intermediate layer of a resin composition formed by incorporating an organic metal complex of a transition metal into a gas-barrier resin having a specific oxygen permeation coefficient and a specific water absorption, and outer and inner layers of a moisture-resistant thermoplastic resin disposed on both the sides of the intermediate layer. This vessel shows an excellent resistance to the permeation of oxygen even under conditions where water and heat simultaneously act.
