<p>The present invention provides a multi-layer structural body, comprising: a first layer 1 of which oxygen permeability is less than 100cc/m<2>.day.atm (23 DEG C, 100%RH) and which is resistant to gas permeation; a second layer 2 which comprises resin, of which the oxygen permeability coefficient is 200cc.0.1mm/m<2>.day.atm (23 DEG C, 100%RH) or more, and a granular oxygen absorber, which is dispersed in the resin and which contains an oxygen absorber composition which exhibits a deoxidization reaction when moisture is supplied thereto, such second layer being laminated over the first layer 1 and having a deoxidizing property; and a third layer 3 of which oxygen permeability is 100cc/m<2>.day.atm (23 DEG C, 100%RH) or more, which is laminated over the second layer 2, and which is permeable to air. This multi-layer structural body itself has an oxygen absorbing performance and is capable of actively and efficiently absorbing oxygen just like a conventional small bag which contains an oxygen absorber composition, without any special treatment such as heat treatment. <IMAGE></p> |
