A system for hydrogen formation includes a container and at least one object. The container defines a reservoir and is flexible along the reservoir. The container forms a gas-tight seal between the reservoir and an atmosphere outside of the container. The at least one object includes aluminum in an activated form. The at least one object is disposed in an inert environment in the reservoir, and the activated form of the aluminum reactable to produce hydrogen in the reservoir upon exposure to water.

[Problem] To provide: a film which is for aging meat and which is relatively easy to treat and allows meat to be aged more safely and effectively; and a film which is for preserving meat and can effectively suppress the deterioration of color or the like of fresh meat.

[Solution] The present invention relates to a film for preserving meat, the film being characterized by: (1) including a hydrogen generating layer containing hydrogen generating particles which can generate a molecular hydrogen upon reacting with water; and (2) using the film in a state in which the hydrogen generating layer is directly contacted with the surface of the meat.
