Abstract:
1. A multilayered plastic container comprising an oxygen-barrier layer of an ethylene-vinyl alcohol copolymer that serves as a matrix and an adhesive intermediate layer of a blend of an ethylene-vinyl alcohol copolymer and a maleic anhydride-modified olefin resin neighboring each other between an inner layer and an outer layer, wherein: both the ethylene-vinyl alcohol copolymer used for forming said oxygen-barrier layer and the ethylene-vinyl alcohol copolymer used for forming said adhesive intermediate layer have an ethylene content of 20 to 60 mol %; and said adhesive intermediate layer contains said ethylene-vinyl alcohol copolymer and the maleic anhydride-modified olefin resin at a weight ratio of 4:6 to 8:2, and contains, as said maleic anhydride-modified olefin resin, a high MFR component having an MFR at 190° C. of 100 to 500 g/10 min. and a low MFR component having an MFR at 190° C. of 2 to 90 g/10 min.
