Title:
ADHESIVE SHEET FOR MAINTAINING STERILIZATION AND FRESHNESS OF PACKING GOODS AND METHOD THEREOF
Document Type and Number:
Japanese Patent JP3121887
Kind Code:
B2
Abstract:
PURPOSE: To maintain sterilization and freshness sufficiently in spite of low gastightness, by providing an adhesive layer impregnated with isothiocyanic ester onto a base sheet whose isothiocyanic ester permeability is low compared to that of a packaging material for packaging goods.
CONSTITUTION: An adhesive layer 2 impregnated with isothiocyanic ester is provided on a base sheet 1 comprised of a polyethylene terephthalate film la and an Al deposited film provided on one side of the film 1a. Further, via the adhesive layer 2, an isothiocyanic ester barrier release sheet 3 comprised of a polyethylene terephthalate film 3a and a silicon release processing layer 3b provided on oneside of the film 3a is bonded to the sheet 1. Thus, because the isothiocyanic ester is supplied from the adhesive sheet even if there is a slight leak, sterilization and freshness can be sufficiently maintained in spite of low gastightness.
