ABSTRACT:
There is provided a method of continuously producing a highly oriented heat shrinkable single layer of amorphous styrene foam or a composite of a thermoplastic film and an amorphous polystyrene foam to form a heat shrinkable two-layer sheet that is easily stored without substantial shrinkage at ambient temperature, the outstanding single-layer sheet or two-layer sheet being adapted for heat shrinking rapidly to form a label around a container or a cup. The outstanding method comprises extruding a single foam sheet or coextruding a thermoplastic film and an amorphous polystyrene foam layer to form the two-layer sheet, bringing the sheet to its orientation temperature, stretching the two-layer sheet at its orientation temperature in at least a longitudinal direction to provide a dimensionally stable, storable, oriented polystyrene foam sheet or a thermoplastic film/amorphous polystyrene foam layer sheet, printing on the oriented sheet to decorate the same, and heat shrinking the sheet to form a final attractive, decorated structure.
