Multilayer polymeric/inorganic oxide structure with top coat for enhanced gas or vapor barrier and method for making same

A coated multilayer beverage container body comprising:

• a polymeric base layer;
• an inorganic oxide gas barrier layer on a surface of the polymeric base layer;
• and
• a top coat on the inorganic oxide gas barrier layer, the top coat comprising a polymeric soluble compound wherein the permeability of the multilayer structure to gas or vapor is reduced, wherein the polymeric soluble compound is selected from the group consisting of carboxymethyl cellulose, poly(acrylamide), and polydextrose.

A coated multilayer beverage container body comprising:

• a polymeric base layer;
• an inorganic oxide gas barrier layer on a surface of the polymeric base layer;
• and
• a top coat on the inorganic oxide gas barrier layer, the top coat comprising a monomeric water soluble compound wherein the permeability of the multilayer structure to gas or vapor is reduced.

A coated multilayer rigid beverage container body comprising:

• a polymeric base layer;
• an inorganic oxide gas barrier layer on an exterior surface of the polymeric base layer;
• and
• a top coat on the inorganic, oxide gas barrier layer, the top coat comprising a monomeric water soluble compound wherein the permeability of the rigid container body to gas or vapor is reduced.
