Abstract

A copolyester resin film laminated metal sheet having excellent formability and a method for its production is disclosed. This disclosure comprises laminating a biaxially oriented copolyester resin film having specified characteristics, to one or both sides of a surface treated metal sheet, which has been heated to the melting point of the copolyester resin film ? 50°C, just before the lamination of the copolyester resin film. This film has been precoated with a resin composite containing in its molecular structure at least one radical, such as epoxy radical and hydroxyl radical. The side of the copolyester resin film pre-coated with resin composite is in contact with the surface treated metal sheet. This copolyester resin film laminated metal sheet is suitable for some applications in which severe formability is required, such as deeply drawn cans formed by multiple drawings, drawn and partially ironed cans, drawn and stretch formed cans, can ends wherein a tab for easy opening is attached, screwed caps and crown caps.
