1. A molding packaging material comprising:
an outer base material layer made of a heat resistant resin;
an inner sealant layer;
a metal foil layer arranged between the outer base material layer and the inner sealant layer; and
a matte coat layer on an outer side of the outer base material layer, the outer side of the outer base material layer being opposite to a side of the outer base material layer facing the metal foil layer; wherein
the matte coat layer includes a resin component, a solid fine particle, and a lubricant; and
the inner sealant layer includes a thermoplastic resin and a lubricant;
the resin component is at least one of a resin selected from the group consisting of an acrylic-based resin, an epoxy-based resin, an urethane-based resin, a polyolefin-based resin, a fluorine-based resin, and a phenoxy resin;
a content rate of the lubricant in the matte coat layer is within a range of 5,000 ppm to 15,000 ppm; and
the content rate of the lubricant in the matte coat layer is greater than a content rate of the lubricant in the inner sealant layer.
