A molding packaging material comprising:

• a substrate layer as an outer layer;
• a heat fusible resin layer as an inner layer;
• and
• a metal foil layer arranged between the substrate layer and the heat fusible resin layer,
• wherein the heat fusible resin layer is composed of a single layer or a multi-layer,
• wherein an innermost layer of the heat fusible resin layer is made of a resin composition containing a heat fusible resin, a roughening material, a slip agent, and a fluoropolymer-based lubricant,
• wherein the roughening material contains a thermoplastic resin, and
• wherein a first lubricative layer containing the fluoropolymer-based lubricant in a content rate greater than 50 mass % is formed on an inner surface of the innermost layer.
