PROBLEM TO BE SOLVED: To obtain an excellent deoxidizing speed by providing a barrier film obtained by combining and layering a resin layer of a non-porous film and a protective layer formed of a finely porous resin composition having a granular water solution retarding filler dispersed therein, on an absorbing face of a finely porous deoxidizing resin layer having excellent deoxidizing performance. SOLUTION: A deoxidizing multilayer body comprises at least a deoxidizing layer 3 formed of a continuously and finely porous resin composition having a deoxidizing component dispersed therein, an oxygen permeating layer 1 formed of a thermoplastic resin of non-porous thin film, and an oxygen permeating layer 2 formed of a continuously and finely porous resin composition having a granular water solution retarding filler dispersed therein. Also, at least on one face of the deoxidizing layer 3, one or more of layers of the oxygen permeating layers 1 and 2 are combined and layered so as to form a barrier layer, wherein adjacent layers are fused with each other so as to form an oxygen absorbing face. When the oxygen permeating layers are to be provided on both faces, a barrier layer 4 is layered on other face of the deoxidizing layer 3 having the oxygen permeating layer on one face. |
