CANS AND A METHOD FOR MAKING CANS

摘要

A can, for holding foodstuffs or similar material, has walls of a thin steel sheet, with the inner surface having a layer of thermoplastic resin thereon; preferably with a thickness of 3 to 100 microns. A foil of aluminum and/or aluminium alloy to a preferred thickness of 5 to 100 microns is provided on the resin layer, with a layer of thermosetting resin on the foil. Such a can has a good corrosion resistance. The can is formed from a steel sheet on which the thermoplastic resin and the foil are pre-coated, and the thermosetting resin applied subsequently.
