Explore our top-tier selection of food-grade tinplate lids, high-speed SOT/RPT easy-open ends, sleek aluminium beverage cans, and specialized industrial powder closures designed for global manufacturing compliance.
Modern industrial metal packaging demands an uncompromising fusion of advanced metallurgy, chemical engineering, and mechanical precision. As a global leading manufacturer operating out of Shanghai, our production ecosystem transforms virgin aluminium alloys into ultra-reliable, shelf-stable, and aesthetically distinctive packaging solutions. From high-speed 2-piece drawn and ironed (DWI) beverage cans to hermetically sealed easy-open ends (EOE) and specialized coloured aluminium foil stocks, we deliver verified Information Gain across every tier of the global packaging value chain.
The mechanical performance of metal packaging relies entirely on precise alloy chemistry and temper selection. Our factory utilizes high-purity aluminium coils tailored specifically for drawability, score line integrity, and internal pressure retention:
Formulated with optimal Manganese (Mn) and Magnesium (Mg) ratios, 3104-H19 exhibits extreme tensile strength and superior deep-drawing capability. This allows us to achieve wall thinning down to 0.095mm while guaranteeing an axial crush strength exceeding 1.2 kN, vital for high-speed filling lines running over 1,500 cans per minute.
Designed specifically for easy-open ends, 5182-H48 provides high work-hardening capacity and exceptional buckle resistance. Its balanced grain structure prevents micro-cracking during scoring and rivetting operations, ensuring reliable pop-and-pull mechanics across extreme pressure variations.
Our lacquered coloured aluminium foil and pull-tab stocks utilize 8011-O/H18 and 5052-H19 alloys. These materials feature high pinhole resistance, excellent ductility for intricate embossing, and absolute barrier protection against moisture, gas ingress, and light degradation.
| Alloy & Temper | Primary Application | Tensile Strength (MPa) | Yield Strength (MPa) | Key Performance Attribute |
|---|---|---|---|---|
| 3104-H19 | 2-Piece DWI Can Bodies | 270 - 310 | 250 - 290 | Optimal ironability, low earing rate (< 2%) |
| 5182-H48 | 200# / 202# SOT & RPT Shells | 360 - 410 | 310 - 360 | High buckle pressure resistance (> 6.2 bar) |
| 5052-H19 | Easy-Open Ring Pull Tabs | 290 - 340 | 260 - 310 | Zero-fracture rivetting & crisp tactile feedback |
| 8011-H18 | Coloured Heat-Seal Foil & Lids | 140 - 180 | 120 - 160 | Pinhole-free, vibrant UV-cured color coatings |
Strategic sourcing in today's volatile global economy requires more than just competitive unit pricing—it demands total supply chain security, rapid scalability, and seamless international port logistics. Located at the heart of Shanghai's industrial manufacturing corridor, our facility leverages China's end-to-end aluminium processing ecosystem.
Our direct partnerships with top-tier smelting and hot-rolling mills guarantee prioritized access to raw ingot allocations. This vertical synchronization cushions our international procurement partners from sudden global LME price spikes while assuring consistent coil-to-coil chemical composition.
Operating multi-station high-speed conversion lines (Minster, Stolle, and Buhrke tooling setups), our factory maintains an annual output capacity exceeding 3.5 billion ends and 1.2 billion drawn aluminium cans. Every line is integrated with vision inspection software capturing micro-defects at speeds above 3,000 ppm.
Being within 60 kilometers of the Port of Shanghai—the world's busiest container gateway—enables short inland transit times, immediate container packing, and access to direct ocean freight lanes. Freight leads to European, North American, Middle Eastern, and Latin American ports are shortened by up to 7–10 days compared to inland suppliers.
Procurement decisions in multinational beverage and food conglomerates extend far beyond basic per-thousand unit costs. Line downtime caused by jammed end feeds, flange splits, or double-seam micro-leaks can cost tens of thousands of dollars per hour. We solve these risks before production begins through structured engineering alignment.
Our technical team evaluates your exact seaming chuck and roll geometry (Ferrum, Angelus, Continental Can, or Somme). We provide customized end curl radius, countersink depth, and compound placement parameters to ensure your seam thickness, seam tightness (> 85%), overlap percentage (> 55%), and body hook length meet strict internal QA benchmarks.
High-acid fruit juices, craft beers, carbonated soft drinks, and saline nutritional products demand zero coating breakdown. Every batch undergoes strict High-Voltage Enamel Conductivity Testing (WACO Enamel Rater). We guarantee readings below 0.5 mA, eliminating risk of metal ion dissolution or flavor scalping.
Export packaging features heavy-duty corrugated slip sheets, high-density polyethylene sleeves, desiccant bags, top wooden frames, and 5-layer stretch-wrap hoods. This prevents moisture condensation, fret corrosion, and pallet tilt during 40-foot high-cube ocean voyages across humid tropical lanes.
Regulatory landscapes across North America, the European Union, East Asia, and the Middle East continue to tighten around food-contact materials. Shanghai Friend Metals Technology maintains comprehensive compliance portfolios to ensure rapid customs entry and zero recall vulnerability.
To satisfy EU Regulation 2024/1987 and strict California Proposition 65 guidelines, our complete line of coloured aluminium foil and easy-open lids utilizes advanced polyester, acrylic, or vinyl-organosol lacquers certified completely free of Bisphenol A (BPA-NI), Bisphenol S (BPS), and phthalates.
Every internal lacquer formulation undergoes third-party overall and specific migration testing under extreme simulant exposures (3% Acetic Acid, 10% Ethanol, Rectified Olive Oil) by SGS/TÜV Rheinland. Full declarations of compliance (DoC) accompany every ocean shipping manifest.
Our manufacturing plants operate under certified ISO 9001 Quality Management and FSSC 22000 Food Safety System certification. Lubricants used in stamping and rivetting are 100% NSF H1 food-grade certified, ensuring compliance for global consumer markets.
The global packaging sector is undergoing a monumental shift toward infinite recyclability and carbon footprint reduction. Aluminium packaging stands out as the ultimate circular substrate—over 75% of all aluminium ever produced remains in productive use today.
Through advanced finite element analysis (FEA) and optimized countersink geometry, we have successfully reduced 202# end shell thickness from 0.224mm to 0.208mm without sacrificing buckle resistance. This saves hundreds of metric tons of raw metal annually for high-volume fillers, directly cutting Scope 3 carbon emissions.
Leveraging state-of-the-art continuous coil anodizing and UV-cured lacquering technology, our coloured aluminium foils and decorated ends feature scratch-resistant matte, high-gloss metallic, holographic, and thermochromic visual effects. Custom Pantone color matching ensures high shelf differentiation for premium beverage and cosmetics lines.
Smart packaging integration is expanding rapidly. We provide high-precision top-of-tab and under-tab laser etching for promotional codes, anti-counterfeiting verification, and consumer engagement tracking—operating flawlessly on high-speed consumer scanning platforms.
