PROBLEM TO BE SOLVED: To provide an oxygen-absorbable hermetic container which is not sensitive to a metal detector, from which a bad smell is not emitted after oxygen is absorbed, which has excellent oxygen absorption performance, and in which a new oxygen-absorbable multilayer body is used as a lid material.SOLUTION: The oxygen-absorbable hermetic container comprises: the lid material that contains the oxygen-absorbable multilayer body which is obtained by layering, in this order, a sealant layer containing a thermoplastic resin, an oxygen absorption layer comprising an oxygen-absorbable resin composition containing a copolymerizable polyolefin compound and a transition metal catalyst, and a gas barrier layer containing a gas barrier substance and which comprises at least three these layers; and a gas-barrier molded container that is obtained by layering, in this order, an inner layer containing the thermoplastic resin, a gas barrier layer containing the gas barrier substance, and an outer layer containing the thermoplastic resin and that comprises at least three these layers. The oxygen-absorbable hermetic container is obtained by joining the sealant layer of the lid material to the inner layer of the gas-barrier molded container. The copolymerizable polyolefin compound contains a constituent unit having at least one tetralin ring. |
