PROBLEM TO BE SOLVED: To suppress a gray color-darkening, and improve an whitening effect by providing at least two layers of white coloring layers, and inserting at least one layer of a synthetic resin film layer between the white coloring layers in a laminated body for packaging, which includes an aluminum layer. SOLUTION: This packaging material 1 for foods, beverages and medicines or the like for which a high gas barrier property and a light-shielding property are required, is formed by providing a white coloring layer 3a, a transparent synthetic resin film layer 4 and a white coloring layer 3b, on one surface of an aluminum layer 2. By this constitution, the improvement of the brightness by an angle of incidence, and the suppressing effect of a gray color which the aluminum layer 2 has can be increased. The synthetic resin film 4 is not specifically limited, and a drawn film of polyethylene, polyvinyl chloride, and a polyamide based resin or the like can be used. In this case, the thickness is preferably 3μm or higher, more preferably, is set in a range of 3 to 200μm. Also, for the aluminum layer 2, an aluminum foil or a deposited aluminum can be used.
