A container body (12) is made from a composite sheet (70) having a metal layer (72) which has at least one side covered by a corrosion-resistant layer (74), such as a layer of thermoplastic. The sheet (70) is moved under one or more high-pressure water jets which remove a strip of the corrosion-resistant layer (74) in the path of the water stream (82), leaving an exposed area (78). The composite sheet (70) may be segmented as necessary to form blanks (90) suitable for forming individual container bodies (12). Each blank (90) is formed generally into a tube or cylinder so that the corrosion-resistant layer (74) faces interiorly, and so that the exposed areas (78) are respectively located at overlapping ends of the blank (90). The overlapping, exposed areas (78) are then welded along a seam (62), forming a seal.
