A food packaging container having a flanged container body of a laminate sheet which comprises a layer of aluminum foil and at leasat 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 .mu.m in thickness, 9.0-25.0 kgf/mm.sup.2 in tensile strength, 2.5-9.5 kgf/mm.sup.2 in proof stress, 10 to 40% in elongation and up to 7% in earing ratio. The resin layer comprises a thermoplastic resin 100-500 .mu.m in thicknes, 0.92-1.08 in the ratio of modulus of elasticity in tension in the machine directon (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.

Food packaging container

A closure material for sealing glass containers comprising a metal foil and a thermally adhesive composition layer formed on one surface of the metal foil and comprising a carboxyl-modified saponified product of ethylene-vinyl acetate copolymer and up to 30 parts by weight of an inorganic compound per 100 parts by weight of the carboxyl-modified saponified product, the carboxyl-modified saponified product being prepared by graft-polymerizing a carboxylic acid group-containing unsaturated compound with a saponified product of ethylene-vinyl acetate copolymer containing 50 to 97 mole % of ethylene.
