ABSTRACT:
A resinous composition excellent in processability and gas permeation resistance, which comprises (A) 30 to 98 % by weight of a crystalline polyolefin, (B) 2 to 70 % by weight of a saponified product of an ethylene-vinyl acetate copolymer having an ethylene content of 25 to 75 mole % and a degree of saponification of at least 93 %, and (C) 0.5 to 15 parts by weight, per 100 parts by weight of said polyolefin and ethylene-vinyl acetate copolymer saponified product, of a thermoplastic polymer containing a carbonyl group in the main or side chain thereof, and a molded structure formed therefrom, which has a specific multi-layer structure and a high gas permeation resistance.
