ABSTRACT:
Beverage or food containers made from sheet material, and methods of making such containers. Such container comprises a layer of paperboard and an expanded foam layer applied as a coating in a liquid carrier, and affixed to a paperboard base layer. The expanded foam has a remote surface preferably defined by intermingled peaks and valleys. The sheet material can include a protective cover layer overlying the remote surface. Such cover layer can comprise paper, plastic film, or foamed thermoplastic. The sheet material can include a heat seal layer, with the heat seal layer overlying, and in surface-to-surface contact with, the foam layer such that the foam layer is between the paperboard and the heat seal layer. Preferred composition for the foam layer is PVDC or AMM.
