Abstract: A molding packaging material includes a heat resistant resin layer as an outer layer, a metal foil layer, and a first adhesive agent layer arranged there between. The first adhesive agent layer is constituted by an adhesive agent containing a two-part curing type polyester polyurethane resin made of a polyester resin as a main ingredient and a multifunctional isocyanate compound as a curing agent. The polyester resin is made from dicarboxylic acid and dialcohol, the dicarboxylic acid contains aliphatic carboxylic acid whose number of methylene of a methylene chain is an even number and aromatic carboxylic acid, and a content rate of the aromatic carboxylic acid to a total amount of aliphatic carboxylic acid and aromatic carboxylic acid is 40 to 80 mol %. The polyester resin is 8,000 to 25,000 in number average molecular weight (Mn) and 15,000 to 50,000 in weight average molecular weight (Mw), and a ratio thereof (Mw/Mn) is 1.3 to 2.5.
