Food packaging container. |
摘要 |
<p>A food packaging container (10) having a flanged container body (11,12) of a laminate sheet (1) which comprises a layer of aluminum foil (2) and at least one thermoplastic resin layer (3) joined to one surface of the foil layer (2). The container body is prepared by deep-drawing the laminate sheet (1) with the resin layer (3) inside. The aluminum foil is 40 - 200 mu m in thickness, 9.0 - 25.0 kgf/mm<2> in tensile strength, 2.5 - 9.5 kgf/mm<2> in proof stress, 10 to 40% in elongation and up to 7% in earing. The resin layer comprises a thermoplastic resin 100 - 500 mu m 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.</p> |
