<p>PURPOSE:To obtain a package having stable oxygen scavenging capacity by laminating a perforated plastic laminated film and a film having pores by a specific film layer and making the perforated plastic laminated film outside to seal an oxygen scavenger. CONSTITUTION:A perforated plastic laminated film 1 and a microporous plastic film 2 permitting no water to pass under atmospheric pressure are laminated and a resin 3 having a softening point equal to or less than that of the film 2 and formed as a large number of strip patterns or a fine reticulated pattern is laminated to the other surface of the film 2 to prepare a packing material whose Gurley air permeability is 1-10000sec/100ml. The film 1 of this packing material is made outside to pack and seal an oxygen scavenger 4 such as sulfite or hydroquinone to form an oxygen scavenger package. This oxygen scavenger package has stable oxygen scavenging capacity and is excellent in water resistance and oil resistance.</p> |
