On a can body, including a can casing, which is closed around the can axis and includes a metal layer, and a closure part, which includes a metal layer, a laser connection is produced between the metal layers of the can casing and the closure part in an overlapping region of the closure part and the can casing. In at least one embodiment, the laser connection includes a plurality of perforations along the connecting line, or a plurality of narrowly delimited regions, in which the two metal layers are melted together. A plastic material is arranged on the laser connection. The laser connection ensures stability, and the plastic material ensures leak tightness, of the connection between the can casing and closure part.
