OXYGEN INDICATOR PACKAGING MATERIAL

摘要

PROBLEM TO BE SOLVED: To suppress a deterioration of an oxygen indicator by light without increasing a work process in the oxygen indicator packaging material constituted by laminating the oxygen indicator 1 having an oxygen detecting function on one side of a base material 31. SOLUTION: The laminating surface of the oxygen indicator 1 is laid with at least one layer of a base material 32 to provide an ultraviolet cutting-off function to an adhesive layer 21 on which the base material 32 is bonded. Alternatively, the surface opposite to the laminating surface of the oxygen indicator 1 is overlaid with at least one layer of a base material 33 to provide an ultraviolet cutting-off function to the adhesive layer 21 to which the base material 33 is bonded.
