View DetailsAn in-depth look at alloy mechanical properties, Draw & Wall Ironing (DWI) physics, and internal liner chemistries.
The standard 330ml beverage can utilizes a highly optimized bi-metallic alloy structure. The body stock relies on 3104-H19 aluminium coil, engineered with specific manganese and magnesium ratios to deliver superior tensile strength (≥275 MPa) and exceptional deep-drawing performance during high-speed wall ironing. Conversely, the 202 SOT / RPT easy-open ends are stamped from 5182-H48 shell stock paired with 5052-H34 tab stock, maximizing tear-groove score integrity while withstanding intense internal carbonation pressures up to 6.2 bar.
Our manufacturing facilities employ multi-stage Draw & Wall Ironing (DWI) systems. High-speed cupping presses transform 0.245mm gauge aluminium sheet into precise shallow cups. Subsequent ironing dies stretch the metal wall down to a ultra-thin 0.095mm mid-wall thickness while maintaining a robust 0.280mm bottom dome thickness. This geometric optimization ensures maximum column strength (axial load >850 N) with absolute minimal raw material consumption, yielding a structural weight under 11.5 grams per 330ml body.
To eliminate organoleptic scalping and ensure long-term shelf-life integrity, internal surfaces are coated using modern BPA-NI (Bisphenol A Non-Intent) modified acrylic or polyester-based liquid polymer lacquers. Applied via high-pressure electrostatic spray nozzles at line speeds exceeding 2,200 cans per minute, the coating layer undergoes rigorous Enamel Rater electrical current testing (<2.0 mA pass threshold), effectively shielding acid-sensitive liquids (pH down to 2.5) from metallic ion migration.

Custom packaging architectures tailored to distinct thermal processing, pressure dynamics, and shelf-life demands.
Carbonated beverages exert continuous outward radial forces. Our 330ml standard cans integrate a engineered bottom dome profile that acts as a pressure vessel, neutralizing bottom push-out phenomena up to 90 PSI. Paired with 202 SOT easy-open ends featuring gas-tight compound lining, CO2 loss is maintained below 0.5% per annum over a 24-month shelf life.
For breweries sensitive to flavor oxidation, dissolved oxygen (TPO) control is critical. Our 330ml sleek line incorporates ultra-smooth neck radii compatible with high-speed under-crown gas flushing (CO2/LN2). Combined with custom-tailored internal modified epoxy or cross-linked acrylic linings, we eliminate sulfur dioxide pickup and organoleptic alteration during tunnel pasteurization (140°F / 60°C up to 30 PU).
Non-carbonated beverages like RTD milk tea, cold brew coffee, and herbal teas require hot-filling (up to 88°C) or retort sterilization (121°C for 20 mins). We supply rigidized 330ml bodies engineered with reinforced body beads or liquid nitrogen dosing options (0.05-0.1g LN2 per can) to create structural internal positive pressure after cooling, preventing sidewall vacuum collapse.
Combining mega-scale automated manufacturing with algorithmic quality assurance for global delivery precision.
Our China manufacturing hubs operate continuous high-speed fully automated lines sourced from industry leaders such as Stolle Machinery and Minster. Utilizing multi-die cupping presses operating at 300 strokes per minute, our facilities achieve an annual output exceeding 1.2 billion units. Automated palletizing, robot-arm strapping, and stretch-wrapping ensure pristine pallet integrity for overseas ocean transit.
Quality control relies on inline high-speed AI optical vision systems. High-resolution CCD cameras monitor 100% of production in real-time, scanning for micro-pinholes down to 0.02mm², neck dents, rim scratches, and internal lacquer voids at speeds up to 3,000 cpm. Non-conforming units are instantly purged via high-pressure air injectors, locking batch defect rates below 50 PPM.
Situated within proximity to major deep-water shipping terminals (Shanghai/Ningbo ports), our supply network integrates direct primary aluminium ingot smelting, continuous casting, precision rolling, and final decoration under one industrial chain. This vertical consolidation eliminates intermediate transport markups, shielding global buyers from price volatility while offering guaranteed 14-day production lead times.
Complete compliance frameworks enabling frictionless import into EU, FDA, and Asian regulatory markets.
Every lot produced is accompanied by comprehensive Migration Test Reports and Certificates of Analysis (CoA). Our products strictly adhere to FDA 21 CFR 175.300 (Resinous and polymeric coatings), EU Regulation 1935/2004/EC, EU No 10/2011, and China's GB 4806.10-2016. Free of heavy metals (Lead, Cadmium, Hexavalent Chromium, Mercury <100 PPM combined per CONEG/94/62/EC).
Leveraging high-speed dry offset metal decoration, we offer up to 8-color CMYK plus spot-color Pantone matching with precision registration (±0.05mm). Advanced surface treatment options include Matte finish, High-Gloss lacquer, Tactile 3D embossing, Thermochromic temperature-sensitive inks, and matte/gloss combination effects designed to boost shelf standout.
To ensure total seaming compatibility with standard counter-pressure filling lines (e.g., Krones, Ferrum, Angelus, Comac), our 202 ends are manufactured within tight mechanical tolerances. We provide comprehensive seam setup specification charts detailing optimum countersink depth (1.8-2.0mm), seam thickness, body hook, and end hook overlaps for zero-defect seaming operations.
Pioneering ultra-lightweighting, 100% PCR recycled alloys, and carbon-neutral packaging solutions.
Through advanced finite element analysis (FEA) and work-hardening metallurgy, our R&D division is driving down incoming sheet gauge from 0.245mm to 0.220mm. This reduction eliminates over 0.8 grams of aluminium per can, directly reducing scope 1 and 2 carbon emissions across the transport lifecycle without compromising axial crush parameters.
Aluminium can be infinitely recycled without loss of metallurgical properties, saving 95% of the energy required for primary smelting. We are expanding our supply of certified 75%+ Post-Consumer Recycled (PCR) coil stock, aiding multinational beverage brands in meeting stringent European plastic replacement directives and global ESG milestones.
Anticipating future chemical restrictions, our end manufacturing lines are transitioning toward 100% PVC-free, phthalate-free water-based sealing compounds. These advanced sealants maintain high elasticity under pasteurization temperatures while complying with emerging global PFAS-free mandates.
Direct answers from our senior packaging engineers regarding specifications, lead times, and compatibility.
For custom 8-color printed 330ml aluminium cans, our standard MOQ starts at 150,000 units per artwork design. This threshold is optimized for high-speed printing plate set-up and ink-change efficiency. For plain (unprinted/bright) cans or standard stock lids, trial orders start at one 40ft High Cube container (~155,000 cans depending on stacking pattern).
Every batch undergoes rigorous quality testing. We utilize high-voltage Enamel Rater testing to measure current leakage through the internal coating; passing values must remain under 2.0mA. Additionally, sample cans are subjected to accelerated corrosion testing using aggressive acid/salt solutions simulating pH 2.3 conditions for 30 days at 40°C to verify zero metal exposure.
SOT (Stay-On Tab) ends retain the tab attached to the can lid after opening, making them the global standard for carbonated soft drinks and beer due to recycling ease and safety. RPT (Redensible / Removeable Pull Tab) ends allow complete detachment of the tab/aperture foil, typically used in specific regional markets or specialized milk powder and food applications.
Can bodies are packed on heavy-duty, reusable plastic or wooden pallets, separated by clean kraft slip sheets and protected by top wooden frames. The entire unit is covered with plastic stretch hoods and multi-band vertical/horizontal strapping. Easy-open ends are packed in sterile plastic sleeves, sealed inside corrugated cartons, and palletized with desiccants to prevent moisture condensation during transit.
