Explore our top-tier precision-drawn aluminum cans, easy-open ends, and high-purity aluminum coils manufactured to meet strict international canning standards.
Strategic dynamics driving global demand for ultra-thin colored foil barriers, eco-friendly aluminum substrates, and high-speed automated canning lines across 2026–2030.
Global consumer brand owners face rigorous legislative pressure (such as the EU Packaging and Packaging Waste Regulation) to phase out non-recyclable multi-layer plastics. Color tin foil and high-grade aluminum offer infinite recyclability with 95% energy savings compared to primary aluminum production.
Leading color tin foil factories are engineering ultra-thin body gauges (down to 0.24mm for 3104-H19 body stock) and end shell stocks (0.21mm for 5182-H48). Thinning raw material while sustaining column strength and buckle resistance directly slashes freight costs and carbon footprint.
Modern beverage and food formulations require next-generation BPA-NI (Bisphenol A Non-Intent) internal lacquer systems. Proprietary polymer coatings safeguard against acidic beverage migration, sulfur staining in protein foods, and moisture degradation in high-humidity logistics channels.
Understanding Total Cost of Ownership (TCO), seamer compatibility, and risk-mitigated freight logistics when contracting color tin foil and metal container suppliers.
For multinational beverage bottlers, pharmaceutical packaging directors, and food brand manufacturers, securing reliable packaging suppliers extends far beyond unit pricing. Disruptions caused by seam pinholes, variable neck curls, or improper surface tension on high-speed filling lines (operating at 1,200 to 2,000 cans per minute) can lead to catastrophic downtime and batch rejection.

Customized container profiles, end closures, and lacquered color tin foils designed for diverse product categories and demanding thermal profiles.
Challenge: Sustaining high internal CO2 pressure (up to 4.2 volumes) while preventing oxygen ingress that ruins fresh hop aromas and flavor profiles.
Engineering Solution: 250ml, 330ml, 473ml, and 500ml standard/sleek body formats constructed from 3104-H19 alloy paired with 202# Stay-On-Tab (SOT) or Resealable (RPT) easy-open lids. Coated with advanced internal lacquers rated for tunnel pasteurization at 65°C.
Challenge: Powdered nutritional items are vulnerable to lipid oxidation, clumping from moisture ingress, and static charge accumulation during pneumatic filling.
Engineering Solution: 300#, 307#, 401#, and 502# specialty powder lids featuring aluminum peel-off membranes or rigid easy-open ends. Integrated with anti-static food-grade inner coatings and nitrogen-flush verification to guarantee near-zero residual headspace oxygen.
Challenge: Hermetic containers must withstand thermal expansion during autoclaving/sterilization cycles (up to 121°C–130°C for 45 minutes) without seal failure.
Engineering Solution: High-grade 200#, 202#, 300#, and 307# tinplate lids and full-aperture aluminum ends equipped with high-performance organosol compound sealant. Formulated to resist sulfur staining from meat proteins and salt corrosion.
Challenge: Luxury personal care and industrial chemicals demand custom metallic colors, vibrant surface graphics, and high corrosion resistance.
Engineering Solution: Anodized and color-lacquered tin foil rolls, slit aluminum coils (8011/5052), and decorated canister components. Offers 100% barrier against UV light rays, volatile organic compounds (VOCs), and atmospheric oxidation.
Inside our Shanghai production facilities: Advanced alloy metallurgy, high-precision cupping presses, and automated optical seam inspection.
Our raw aluminum coils (3104, 5182, 8011) undergo micro-slitting with digital tension control. High-speed cupping presses convert coil stock into body blanks with zero surface scratching, maintaining uniform wall thickness within ±0.002mm tolerances.
Can bodies pass through multi-stage ironing dies that stretch the aluminum shell to target heights while reducing wall mass. This mechanical deformation creates an optimized ratio between thin sidewalls and a rigid bottom dome engineered for pressure containment.
Every single easy-open lid and drawn container passes through high-speed vision camera systems. Integrated sensors evaluate score line depth, tab placement accuracy, flange integrity, and interior coating continuity at speeds over 1,500 units per minute.
Protecting your global supply chain through full food-contact certification, customized double-seam teardown protocols, and export-grade pallet packaging.
Every batch of color tin foil, tinplate lids, and aluminum beverage cans manufactured by Shanghai Friend Metals Technology Co., Ltd. is supplied with comprehensive food-contact declaration certificates. Our products strictly comply with FDA 21 CFR 175.300, European Union Regulation (EC) No 1935/2004, EU No 10/2011, and China National Standard GB 4806.10.
Each export shipment includes complete coil mill certificates, overall migration test reports, and lot batch codes for end-to-end trace-back in ISO 9001 audit environments.
To eliminate ocean transit oxidation, humidity damage, and pallet shifting, containers are packed using heavy-duty wooden pallets, top frames, moisture-barrier kraft slip sheets, and heat-shrink wrap hooding. Easy-open ends are sealed in heavy-duty polyethylene sleeves with industrial desiccant bags.
Furthermore, our engineering staff provides remote and on-site technical support for your line seamers—recommending exact chuck profiles, countersink depths, and seam teardown parameters (hook overlap, seam tightness %, seam gap) prior to full production runs.
Detailed answers prepared by senior packaging engineers addressing metal alloys, order quantities, custom color tin foil decoration, and line calibration.
Can bodies are manufactured from drawn 3104-H19 alloy, engineered for superior tensile strength during wall ironing. Easy-open ends are stamped from 5182-H48 shell stock with 5052 alloy for opening tabs to achieve ideal pop-and-pull values. Lacquered foil rolls and lid materials utilize 8011 and 3104 tempers. Every coil order is accompanied by original mill test certificates verifying chemical composition, gauge tolerance, and yield strength.
For standard unprinted (bright) aluminum cans or stocked easy-open ends (such as 200#, 202#, 300#, 307#, 401#, 502#), our minimum order starts at one 20 ft shipping container or 200,000 units for trial shipments. Custom dry-offset 6-to-8 color printed cans generally require an MOQ of 100,000 pieces per artwork design to optimize printing plate setup. Standard lead time is 15 to 20 business days from final artwork sign-off and deposit receipt.
Yes, all internal lacquers applied in our plants are 100% BPA-NI (Bisphenol A Non-Intent), formulated using acrylic or polyester-based polymer systems. They undergo rigorous Enamel Rater testing (< 2.0 mA) and migration screening to guarantee chemical inertness against carbonated soft drinks, craft beers, fruit juices, dairy drinks, and aggressive solvent-based liquids.
Before mass production, our application engineers request your exact seamer make and model (e.g., Ferrum, Angelus, Continental Can, Pneumatic Scale). We supply complete technical CAD drawings outlining neck curl, countersink height, and flange width. We also ship sample lots for double-seam teardown evaluation, verifying cover hook, body hook, and seam overlap percentage on your specific line chucks.
We provide a broad range of custom surface aesthetics including matte finish, metallic gloss, tactile embossed patterns, electro-polished color tin foil anodization, and high-resolution dry offset printing up to 8 colors. Special security features, such as UV-fluorescent anti-counterfeiting ink and custom QR code printing on easy-open tab surfaces, are also supported.
