Abstract:
A thermoplastic resin-coated metal sheet obtained by coating at least one surface of a metal sheet with a thermoplastic resin via a polyester type primer, wherein the polyester type primer, if it is in the form of a 10 µ m-thick dry primer sheet, has a breaking elongation in a range of 9 to 200% at a tension speed of 1000 mm/min. and an MEK extractability in a range of 3 to 40%. Without using a special thermoplastic resin-coated film or surface-treated metal sheet, therefore, the cans and can lids can be formed using the thermoplastic resin-coated metal sheet of the invention maintaining excellent and close adhesion during the working, preventing the can body from breaking and the thermoplastic resin coating from peeling at the flange-forming portion during the working, the cans and can lids excelling in dent resistance and economy.
