This invention relates to a compound container which can completely be separated into paper and plastics upon abandonment thereof, whose volume can substantially be reduced upon abandonment, which permits the reduction of the amounts of paper and plastics to be used, which exhibits excellent resistance to falling impact, which has a high oxygen gas barrier properties or water vapor barrier properties. This compound container comprises an inner container of a plastic and an outer container of paper or mainly comprising paper, wherein the inner container is produced by blow-molding or stretch blow-molding a resin composition comprising at least two resins including a barrier resin.

Compound container

The improved resin composition including a polyolefin, a transition metal containing oxidation catalyst and 0-500 ppm of a radical inhibitor can be used to fabricate a sheet and a container that have good oxygen barrier quality on its own without being combined with expensive other resins that have oxygen barrier quality.

Polyolefinic composition having oxygen barrier property, as well as

The saponified product of an ethylene-vinyl acetate copolymer is mixed with an oxidation catalyst to provide a resin composition having improved oxygen barrier quality. For better formability, the composition may be mixed or laminated with another thermoplastic resin such as a polyester.
