Claim:
1. A method for manufacturing a molding packaging material, comprising: a step of subjecting at least one surface of a metallic foil for a barrier layer to chemical conversion treatment; a step of bonding a biaxially oriented polyamide film to the other surface of the metallic foil with an outside adhesive to form an outside substrate layer; a step of applying a resin composition in which 0.1 wt % to 60 wt % of a dispersion of inorganic and/or organic solid fine particles having an average particle diameter of 1 μm to 10 μm is contained in a two component curing type heat-resistant resin to a surface of the outside substrate layer, and then drying to form a matte coat layer whose gloss value is controlled to be 1 to 30%; a step of forming an inside adhesion resin layer having adhesiveness to both the metallic foil as the barrier layer and a resin of an inside sealant layer described later on one chemical conversion-treated surface of the metallic foil; a step of laminating and forming the sealant layer containing a thermoplastic resin on the inside adhesion resin layer; and a step of heat treating a laminate obtained by the steps above with a heat roll heated to 130° C. to 220° C. in such a manner that the outside substrate layer is on the side of the heat roll.
