Composite container and non-foil high-barrier liner therefor

A composite container, comprising:

• a tubular body wall comprising at least one paperboard body ply wrapped into a tubular shape, the body wall having an inner surface of paperboard;
• and
• a two-ply liner adhered to the inner surface of the body wall, the liner comprising a paper outer ply having one side adhered to the inner surface of the body wall, and an inner ply laminated to the paper outer ply by an intervening tie layer, the inner ply comprising a polymer film core layer having an outer surface and an inner surface, a vapor-deposited metal layer joined to the outer surface of the film core layer, and a sealant layer disposed on the inner surface of the film core layer, the sealant layer forming the innermost surface of the container and sealing opposite edges of the liner to each other at a fold seal therebetween;
• wherein the tie layer comprises one of (1) an adhesive layer comprising a urethane-based adhesive, and (2) a coextruded layer having an outer sublayer contiguous with the outer ply and an inner sublayer contiguous with the inner ply, the outer and inner sublayers comprising different polymer materials.
