Molding packaging material, and molded case

A molded case comprising:

• a concave case main body having an opening periphery;
• and
• a flange continuously formed on the opening periphery of the concave case main body,
• wherein the concave case main body and the flange are formed by drawing or bulging a molding packaging material,
• wherein the molding packaging material includes:
• a heat resistant resin layer as an outer layer;
• a metal foil layer;
• and
• a first adhesive agent layer arranged between the heat resistant resin layer and the metal foil layer,
• wherein 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,
• wherein the polyester resins is made from dicarboxylic acid and dialcohol, the dicarboxylic acid contains aliphatic carboxylic acid and aromatic carboxylic acid whose number of methylene of a methylene chain is an even number, 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 %, and
• wherein 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.
