Tin Can Manufacturers & Suppliers

Tin cans (tinplate cans or steel cans) are the standard packaging format for commercially sterilised ambient shelf-stable foods — including vegetables, fruits, fish, meat, soups, pet food, coffee, tea, and confectionery. Three-piece cans consist of a cylindrical body (formed from a flat tinplate blank, seam-welded along one side), a bottom end, and a top end — each produced separately and seamed together. Three-piece can construction is standard for food cans in most size ranges. Two-piece cans (drawn and ironed, or DRD — drawn and re-drawn) are formed from a single flat disc without a side seam — used for shallow-profile cans such as fish tins and some specialty food cans. Interior lacquering is critical for food cans: the lacquer prevents metal-to-food interaction and corrosion. The main lacquer types are: BPA-based epoxy lacquers (the most widely used, providing excellent adhesion and flexibility — but subject to increasing regulatory scrutiny over BPA migration, particularly in some EU member states and the State of California); BPA-free alternatives (acrylic and polyester-based lacquers, and oleoresin (natural resin) lacquers for some traditional applications such as sardine cans). When sourcing tin cans for EU food markets, confirm BPA-free lacquer status with the supplier and request migration test data. Flat tin cans (also called gift tins or decorative tins) — for confectionery, biscuits, tea, and gift packaging — are produced by a different process (drawing from tinplate sheet) and are specified by top opening diameter, can height, and lid type.

The top end (lid) format is an important specification decision for food tin cans. Full-open end (FOE) — the standard for most food cans, opened with a can opener; the classic format for vegetables, fruits, beans, and soups. Easy-open end (EOE) with ring-pull tab — allows consumers to open the can without a can opener, providing convenience; standard for pet food, some fish cans, and convenience meal formats. Aluminium SOT (stay-on tab) — the universal end format for carbonated beverage cans (aluminium); the tab remains attached after opening. Peel-off lid (foil membrane lid) — used for coffee, infant formula, and pharmaceutical applications; the foil lid is heat-sealed to the top of the can after filling, enabling hermetic sealing and an airtight format without a traditional can end. Key quality specifications for tin cans include double-seam integrity (the hermetic seal between body and end), lacquer coverage and adhesion, and dimensional tolerances. For retorted food cans (processed in autoclave), the double-seam specification is critical for seal integrity under retort conditions. Request a double-seam inspection report from the manufacturer covering seam countersink, seam width, seam thickness, and overlap length.
