<p>PROBLEM TO BE SOLVED: To produce a packaging material to which an oxygen absorbing capacity is imparted by applying an oxygen absorbing substance to a base film. SOLUTION: A seal layer 14 having oxygen permeability and air impermeability and made of a thermally adherent resin is laminated on a face of an oxygen absorbing substance coating layer 12 of an oxygen absorbing film 13 which is formed by coating an oxygen absorbing substance comprising a gallic acid compound layer 12a and an alkaline substance compound layer 12b on a base film 11. By this method, since a packaging material itself has an oxygen absorbing capacity, for example, a small bag containing an oxygen absorbing agent is not necessary to be enclosed in a packaging container, and a risk of erroneous eating can be avoided. Moreover, the time required for packing contents such as foodstuffs into the packaging container can be shortened, and cost can be reduced.</p> |
