<p>PROBLEM TO BE SOLVED: To provide a method for manufacturing an oxygen absorbable laminated film having high productivity using a general iron deoxidizer and a packaging material using the same and having excellent durability. SOLUTION: To manufacture the oxygen absorbable laminated film having an oxygen absorption layer D made of an oxygen absorbing resin composition in which a particulate deoxidizer containing an iron powder as a base compound is dispersed in a polyolefin resin and having an oxygen barrier layer A, an intermediate layer B, an adhesion reinforced layer C, the oxygen absorbing layer D and a sealant layer E sequentially laminated from at least an outside, The layer C, the layer D or the layer C, the layer D and the layer E are co- extrusion laminated on a surface of the layer B. In this case, a melt flow rate of the polyolefin resin used for the layer C is smaller than that of the polyolefin resin used for the layer D, and this resin of the layer C is applied.</p> |
