Molding packaging material and molded case
A molding packaging material includes an outer substrate layer made of a heat-resistant resin, an inner sealant layer made of a thermoplastic resin, a metallic foil layer provided between the outer substrate layer and the inner sealant layer, and a protection coat layer formed on a side opposite to the metallic foil layer side of the outer substrate layer. The protection coat layer is made of a resin composition including a main resin containing a phenoxy resin and a urethane resin, and a curing agent, and has a thickness of 0.1 μm to 10 μm.
