Containing the oxygen absorber or its package,
An oxygen-absorbing package formed by sealing the oxygen absorber or its package by heat sealing the inner surface of the laminate. In addition, the second invention of the present application is directed to "the outer layer of poly-4-methylpentene-1 on at least a part of the periphery of the through hole in the lower bottom of the lid, and the heat sealing property of the outer layer itself." An oxygen-absorbing package obtained by heat-sealing the periphery of a laminate comprising an inner layer made of a nonwoven fabric having the oxygen-absorbing agent or its package sealed inside the lid. " .

-A polymer comprising methylpentene-1. The inner layer is preferably made of the following nonwoven fabric having a core-sheath structure. That is, the sheath portion is made of polyethylene such as low-density polyethylene, medium-density polyethylene, high-density polyethylene, or linear low-density polyethylene, and the core portion is made of a plastic having a higher melting point than polyethylene, such as polypropylene, nylon, or polyester. It is.

る。However, heat sealing is difficult with a poly-4-methylpentene-1 single layer, which is not preferable for use as a package.
Therefore, it is necessary to laminate with a breathable material having a lower melting point than poly-4-methylpentene-1. In the case of non-woven fabric consisting of a single plastic such as polyethylene and polypropylene,
Shrinkage occurs and it is difficult to perform good heat sealing. The present invention makes it possible to perform good heat sealing by using the inner layer as described above, preferably an inner layer made of a nonwoven fabric having a core-sheath structure, and to ensure sealing.
