초록 ▼

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.

대표청구항 ▼

A method of continuously producing a highly oriented polystyrene foam sheet which shrinks at substantially lower temperatures to form a label or a cup, the foam sheet being dimensionally stable during shipping and handling and have excellent surface appearance for printing and decoration, the method comprising the steps of: A. extruding an amorphous polystyrene foam sheet as a single layer with little or no orientation during the extrusion; B. heating the foam sheet by contacting hot rolls or by exposing to infrared heaters to the orientation temperature; C. stretching the sheet in a longitudinal direction between a pair of spaced rolls running at different speeds to reduce its thickness, and provide a dimensionally stable, highly oriented structure; D. printing on the oriented sheet to decorate the same to thereby provide a dimensionally stable, decorated sheet; and E. heat shrinking the decorated, oriented sheet to form a final attractive structure.
