ABSTRACT OF THE DISCLOSURE A multi-layer polymeric structure useful for packages comprises at least one protective layer of hydrophobic resin and at least one layer of water-sensitive oxygen barrier resin. This multi-layer polymeric structure is characterized by incorporating in the oxygen barrier layer at least one macro- molecular compound selected from the group consisting of high polymers of a three-dimensional network structure containing hydrophilic groups and water-soluble macromolecular compounds containing ionizing groups. Optionally, the oxygen barrier layer and the protective layer may be joined through the medium of an additional layer of adhesive resin in a laminated form.
