A 3 Piece Can, also known as a Three-Piece Can or Three-Piece Metal Tin Can, is a classic and highly versatile metal container constructed from three distinct components: a cylindrical can body, a bottom end, and a can lid (either a normal lid or an easy open end). Unlike two-piece cans where the sidewall and bottom are pressed from a single piece of material, three-piece cans are manufactured from a flat steel sheet (tinplate or TFS) which is cut, rolled, and side-seamed to form a cylindrical body. The bottom end is then double-seamed onto one end of the can body, while the lid is seamed onto the opposite end after filling. Three-piece cans have been the industry standard for metal food packaging since the 19th century, with an application history dating back to 1810 when British inventor Peter Durand first used tinplate to produce food canning containers.

The 3 Piece Can offers several compelling advantages that have made it the preferred packaging solution for countless food products worldwide.
