A method of producing metal cans and metal cans produced thereby

摘要

A process for producing metal cans (7) from a feedstock (1) comprising a low carbon steel strip or sheet coated on each of its surfaces with a coherent laminated coating of a thermoplastic polymer material. The process includes one or more redrawing stages in which the side walls are reduced in thickness by a stretching operation, and forming in the can base an inwardly projecting dome bordered by upstanding walls which subtend an angle of between 0 and 5 DEG to the vertical. <IMAGE>
