Abstract
A composite resin film enabling a severe forming processing, in which a drum portion or a can is made thinner than a conventional one when the resin film coats a metallic sheet to be formed into a can, maintaining a favorable flavor even when time elapses after contents are filled in the resulting can, and having a high impact resistance which makes the film free from crack even if the resin film is acted on by an impact from outside before and after the filling of contents, and a metallic sheet coated with the resin and having a laminated structure of the composite resin film. The metallic sheet coated with the composite resin film is such that a resin having three layers, an upper layer composed of a resin entirely composed of polyester resin, an intermediate layer composed of a blended resin containing polyester resin and polycarbonate resin, and a lower layer composed of a blended resin containing polyester resin and polycarbonate resin, is laminated on a metallic sheet.
