A container comprising at least one layer of a gas permeable polymer selected from the group consisting of polyesters, polycarbonates or polyolefins, and at least one layer of an ungelled thermoplastic resin comprising a reaction product of a polyamine essentially devoid of oxyalkylene moieties and containing up to about two primary amino nitrogen groups per molecule and a polyepoxide, the polyamine and the polyepoxide present in the reaction mixture at a ratio of from about 1.4:1 to about 0.83:1 based upon moles of polyamine to moles of polyepoxide; the ungelled resin is further characterized as containing at least about seven percent by weight amine nitrogen.
