A food packaging container having a flanged container body of a laminate sheet which comprises a layer of aluminum foil and at least one thermoplastic resin layer joined to one surface of the foil layer. The container body is prepared by deep-drawing the laminate sheet with the resin layer inside. The aluminum foil is 40 - 200 µm in thickness, 9.0 - 25.0 kgf/mm2 in tensile strength, 2.5 - 9.5 kgf/mm2 in proof stress, 10 to 40% in elongation and up to 7% in earing ratio. The resin layer comprises a thermoplastic resin 100 - 500 µm in thickness, 0.92 - 1.08 in the ratio of modulus of elasticity in tension in the machine direction (MD) to that in the transverse direction (TD), 0.60 - 1.40 in the MD/TD ratio of elongation and 0.40 - 1.60 in the MD/TD ratio of breaking strength.
