PROBLEM TO BE SOLVED: To provide a lid material for a container suitable for maintaining gas barrier property that a film material includes at high level when receiving physical stress.SOLUTION: Provided is the lid material for a container having a film material which has a function as part of a partition wall for partitioning inside and outside of the container in a state that the lid material is assembled to a container body and the container is formed. The film material includes a multilayer structure including a base material (X), a layer (Y), and a layer (Z) respectively one or more layers. The layer (Y) includes an aluminum atom, and the layer (Z) includes a polymer (E) including a monomer unit including a phosphorus atom. In the multilayer structure, at least one set of the layer (Y) and the layer (Z) is laminated adjacently. |
