To provide an aluminum material with a multilayered film for press work and a press work method for the same suppressing break and peeling of the film during press work and allowing visual recognition of the break and peeling if they occur.
In the aluminum material 1 with the multilayered film 3 for press work and the press work method for the same, the multilayered film 3 formed by laminating a resin film layer 31, a printing layer 32 and an adhesive layer 33 is stuck to the surface of the aluminum material 2 on the adhesive layer 33. The resin film layer 31 comprises a resin film mainly composed of polypropylene resin. The printing layer 32 is formed by applying printing ink on a resin film, and the adhesive layer 33 comprises an adhesive. In the press work, the multilayered film 3 side of the aluminum material 1 including the multilayered film 3 for press work is arranged in a press working machine to face the die side, and the aluminum material 1 including the multilayered film 3 for press work is protruded to the die side.
