    • A packaging container having an oxygen absorption layer composed of a base resin component (component A) and a component with oxygen absorption capability (component B), wherein the oxygen absorption layer has such a sea-island dispersion structure that the base resin component (component A) constitutes the sea portion while the component with oxygen absorption capability (component B) constitutes the island portions and wherein the ratio of the total surface area (N cm2) of island portions constituted of the component with oxygen absorption capability (component B) in the oxygen absorption layer to the internal volume of packaging container (M cm3), N/M, is 20 cm-1 or greater. As a result, not only does the packaging container excel in gas barrier and oxygen absorption properties from the initial stage of filling of contents but also the initial oxygen concentration of contents can be lowered continuously from the initial stage of filling.
    • 具有由基础树脂组分(A组分)和具有氧吸收能力的组分(组分B)组成的氧吸收层的包装容器,其中氧吸收层具有这样的海岛分散结构,即基础树脂组分(组分 A)构成海水部分,而具有氧吸收能力的组分(B组分)构成岛部分,其中由具有氧吸收能力的组分构成的岛部分的总表面积(N cm2)的比例(B) 包装容器的内部容积(Mcm 3)的氧吸收层N / M为20cm -1以上。 结果,不仅包装容器从填充内容物的初始阶段优良的气体阻隔性和氧气吸收性,而且从填充的初始阶段可以连续地降低内容物的初始氧浓度。
