PROBLEM TO BE SOLVED: To provide a packaging material, for packaging dried foods in a bag with a drying cake, which has paper and a resin thinned by modifying a resin interposed between the paper and an aluminum foil and prevents the breakage of the packaging material by the drying cake constituting the dried foods from occurring by enhancing a piercing strength. SOLUTION: In the packaging material formed of a paper layer 1, an aluminum foil layer 5 and a sealant layer 6, a resin layer 4 of a polyethylene terephthalate film is laminated between the paper layer 1 and the aluminum foil layer 5, or the resin layer 4 of the polyethylene terephthalate film is laminated on both sides of the resin layer 4 through extruded polyethylene resin layers 3 and 3.
