EXPANDED HEAT INSULATING LABEL EXCELLENT IN HEAT RESISTANCE AND PACKAGE FILLED WITH WARMED DRINK

摘要

PROBLEM TO BE SOLVED: To improve heat resistance of an expanded heat insulating label to be formed as a heat insulating layer on the surface of a drink-filled package warmed on sale in a store, thereby preventing thermal damage on the label which is prone to be caused when the drink is heated and thermally insulated.;SOLUTION: This expanded heat insulating label is made of an expanded polystyrene sheet as a base material (11), and the base material (11) has a layer structure coated with an ultraviolet- or electron beam-curing resin film (protection film) on one face (the front side when the base material is attached to the drink-filled package). The protection film is formed at least either as an ultraviolet- or electron-curing ink printed layer (12) or as an ultraviolet- or electron-curing varnish printed layer (13).;COPYRIGHT: (C)2004,JPO
