ABSTRACT:
There is disclosed herein improved packages, and methods of forming same, of the type wherein a container, such as for example a glass container, like a bottle or jar, is provided externally thereof with a heat-shrunk, cellular thermoplastic member, circumferentially and snugly engaging a sidewall portion of the container; the improvement resides in employing, as the thermoplastic member, a composite structure, or laminate, of a closed cellular polymeric layer preponderantly of polystyrene having incorporated therein from zero weight percent up to compatible amounts of a copolymer of ethylene and an alkyl ester of alpha-beta monoethylenically unsaturated carboxylic acid or a copolymer of ethylene and vinyl acetate or a copolymer of ethylene and an alpha-beta monoethylenically unsaturated carboxylic acid, or mixtures thereof, and, in adhered relationship to said cellular layer, a layer of a noncellular polymeric material preponderantly of ethylene moieties having incorporated therein moieties of vinyl acetate, or an alkyl ester of alpha-beta monoethylenically unsaturated carboxylic acid, or an alpha-beta monoethylenically unsaturated carboxylic acid, or mixtures thereof.
