Metal packaging can body, for use in forming a can by attachment of at least one lid, has a generally cylindrical body portion and a flanging rim which is intended for the subsequent attachment of the body portion to the lid. The flanging rim is at least partly of wall thickness greater than that of the body portion. To save material and costs, the flanging rim has at least one portion which decreases in wall thickness in the axial direction away from said body portion. The invention is especially applicable to deep-drawn and ironed products.
