120g (4.25 Oz) Round Three-Piece Metal Cans for Premium Ocean Sardines

Our 120g (4.25 oz) round, three-piece metal can is a globally recognised, reliable packaging solution tailored for the mid-to-high-end marine seafood canning industry. Designed to house premium products such as sardines in oil, herring chunks, or tuna pieces, this robust cylindrical steel container offers superior protection, effectively preventing flavour loss, aroma dissipation, and quality degradation caused by light and atmospheric oxygen. As demonstrated by our "Ocean Sardine" custom packaging sample, we possess exceptional technical expertise in high-definition tinplate printing. By applying specialised multi-layer lithographic coating technology prior to metal sheet forming, we ensure that intricate seafood branding and soft colour tones remain intact—free from cracking, stretching distortion, or coating haze—throughout the subsequent can-making process.

Structural Features and Advantages:

Radial Pressure Distribution: The perfect circular geometry allows the can to uniformly withstand extreme pressure fluctuations during rapid vacuum cooking and high-temperature, high-pressure steam sterilisation cycles (up to 130°C). Micro-bead Stacking Stability: Precision-engineered rim tolerances for the can bottom and top ensure stable stacking on commercial sorting trays, in cartons, and on shipping pallets.

Oil-Resistant Interior Barrier: A specially formulated gold internal resin coating remains completely chemically inert when in contact with high-salinity brine or acidic organic olive oil mixtures. Integrated Easy-Open Safety Lid: The easy-open lid features precision scoring, offering consumer convenience while ensuring a complete airtight seal and safety.

Base Material: Premium electrolytic tinplate (ETP) with consistent hardness;

Closure Component: Precision steel or aluminium Easy-Open End (EOE);

Internal Coating: Dual-cured, sulphur-resistant epoxy-phenolic resin (food-grade);

External Graphics: High-opacity white base coat + CMYK lithographic printing + scratch-resistant protective varnish;

Suitable Contents: Sardines in vegetable oil, smoked fish fillets, squid chunks, mackerel in brine.

❓ Frequently Asked Questions (FAQ)

Q1: Why do commercial seafood brands prefer 120g round cans over wide oval ones? Round cans offer superior radial symmetry, allowing automated processing equipment to perform spinning, labelling, washing, and sealing operations at extremely high speeds without the need for complex orientation-based conveyor systems. This not only reduces upfront tooling costs but also boosts the hourly output of the canning line.

Q2: How does your factory handle printing light colours (such as sky blue) on raw metal sheets? To ensure a crisp, clean look for delicate light-coloured backgrounds on the finished can, our printing lines apply a uniform, high-opacity primer to the reflective steel surface. This effectively prevents the dark metal substrate from showing through, ensuring that text, barcodes, and brand logos remain clearly legible on retail shelves.

Q3: What is the typical lead time for custom-printed 120g seafood cans? Once your packaging designer approves our printing plates—which incorporate pre-press distortion compensation—the standard production cycle for custom bulk orders is typically 25 to 35 days, depending on total order volume and the current schedule of our stamping lines.
