Abstract
A laminated plastic molded body of the present invention comprises a laminated plastic molded body having a layered structure portion of three-layers or five-layers in which a resin layer A and a resin layer B are alternatively laminated, wherein the resin layer A provided at least at the surface side of the layered structure portion is a mixed resin layer of a poly(ethylene terephthalate) resin and at least one resin selected from the group consisting of an amorphous polyester resin, an ethylene naphthalate-ethylene terephthalate copolymer resin and a meta-xylene group-containing polyamide resin, and the resin layer B interposed between the resin layers A is a barrier resin layer comprising at least one resin selected from the group consisting of a meta-xylene group-containing polyamide resin and an ethylene-vinyl alcohol copolymer resin. Thus, a multi-layer laminated plastic container having highly gas barrier properties against oxygen and carbon dioxide gases, and yet transparency, excellent characteristics in mechanical properties, and having food hygiene properties can be provided.
