Abstract
Provided is a molding packaging material that can have an increased use life, can suppress a decrease over time in inter-layer lamination strength, and has superior molding properties in extrusion molding, draw forming, and the like. The laminate molding packaging material contains: an outside substrate layer () comprising a heat-resistant resin; an inside sealant layer () comprising a thermoplastic resin; and a metal foil provided between the two layers as a barrier layer (). In the heat-resistant resin of the outside substrate layer (), a biaxially oriented polyethyleneterephthalate film is used that, when the tensile breaking strength in the M direction is MB and the tensile breaking strength in the T direction is TB, the following are satisfied:500 MPa==700 MPa; and  formula (I)||=30 MPa.  formula (II)
