A multilayer body comprising a sealing layer (A) comprising a thermoplastic resin, an oxygen absorption layer (B) comprising a thermoplastic resin and iron powder, and an oxygen barrier layer (D) having oxygen barrier properties, the layers being laminated in a described order, wherein at least one of the sealing layer (A) and the oxygen absorption layer (B) comprises an ionomer as the thermoplastic resin.

Multilayer body, packaging container, and food storing method

An oxygen-absorbing container includes a container body having a multilayer structure constituted by an innermost layer, an outermost layer and an intermediate layer therebetween, the container body having an opening part on an upper part thereof; and a sealing member bonded to an upper end surface of the opening part of the container body to seal an opening of the opening part. The innermost layer and the intermediate layer are bent outward at an upper end of the opening part and form a flat part and a surface of the flat part forms the upper end surface of the opening part. When the sealing member is unsealed, part of the innermost layer on the upper end surface of the opening part is configured to be peeled off so as to leave an unsealed mark.

Container

There are provided an oxygen absorbing resin composition, an oxygen absorbing multilayered body, and an oxygen absorbing hollow container that can absorb oxygen in an atmosphere even under a low-humidity atmosphere. The oxygen absorbing resin composition includes: (I) an oxygen absorbing agent consisting of a metal (a metal of (I)) obtained by subjecting an alloy comprising (A) at least one transition metal selected from the group consisting of manganese, iron, platinum, and copper group metals and (B) at least one metal selected from the group consisting of aluminum, zinc, tin, lead, magnesium, and silicon, to treatment with an acidic or alkaline aqueous solution to elute and remove at least a part of the component (B); and (II) a thermoplastic resin.
