PROBLEM TO BE SOLVED: To provide a method for preserving a container filled with a liquid chemical over a long period of time while suppressing deterioration of a liquid chemical component.SOLUTION: The method for preserving the container filled with the liquid chemical comprises a step of preserving the container filled with the liquid chemical in an oxygen-absorptive container obtained by using an oxygen-absorptive multilayer body as a whole or partially, which body is obtained by layering a thermoplastic resin-containing sealant layer, an oxygen absorption layer comprising an oxygen-absorptive resin composition containing a copolymerized polyolefin compound and a transition metal catalyst, and a gas barrier layer containing a substance having gas barrier properties in this order and which body comprises at least three layers. The copolymerized polyolefin compound contains a constituent unit having at least one tetralin ring. |
