Molding method and molded food packaging containers of aluminum foil pressing lubricants and food packaging materials using the same

摘要

PROBLEM TO BE SOLVED: To provide a press forming lubricant which has an appropriated viscosity suitable for the aluminum foil press forming lubricant among the lubricants approved as the foods or provisions, high coating film strength and formability, and excels in the surface state of a formed article, an aluminum foil press forming method using the same, and a food packaging container.;SOLUTION: The aluminum foil press forming lubricant is a liquid composition which comprises a 6-12C saturated fatty acid triglyceride and has a coefficient μ of friction of ≤0.16, a proof pressure of ≥2.5 kg/cm², a viscosity at 40°C of ≤30 cst, and a freezing point of ≤-5°C. The aluminum foil press forming method comprises coating the lubricant containing the medium-chain fatty acid triglyceride on an aluminum foil and effecting press forming, and the food packaging container is formed by the press forming.;COPYRIGHT: (C)2003,JPO
