METHOD FOR PRODUCTION OF A COPOLYESTER RESIN FILM LAMINATED METAL SHEET |
摘要 |
A method for producing a copolyester resin film laminated metal sheet having an excellent heat resistance which comprises laminated a biaxially oriented copolyester resin film having specified characteristics on one or both sides of a metal sheet coated with a single layer of hydrated chromium oxide or a double layer consisting of a lower layer of metallic chromium and an upper layer to hydrated chromium oxide which has been heated to a temperature of Tm-50.degree.C to Tm, where Tm represents the melting temperature of said copolyester resin film. This copolyester resin film laminated metal sheet is suitable for the materials for can stock which is reheated for curing the coated lacquer or treated with hot steam for sterilization of food after packing food in the cans, such as deeply drawn cans, drawn and redrawn cans, can ends, screwed caps and crown caps.
