1. Full-Chain In-House Production Capabilities (50M Annual Capacity)

• Raw material: Direct procurement from top 3 global tinplate suppliers (e.g., Baosteel) with 0.2-0.35mm food-grade tinplate (compliant with EU EN 10333 standards);
• Processing: In-house stamping (12 automated lines), welding (precision seam welding), seaming (double-seam technology), and digital printing;
• Product range: Custom round tinplate cans (diameter 50-300mm), 3-piece tinplate cans (height 80-600mm), etc.

2. Advanced Tech for Sealing & Traceability

• Airtightness: 8 fully automated stamping + precision welding lines achieve a 99.85% seal integrity pass rate (tested via pressure decay method), meeting food packaging’s oxygen/moisture barrier requirements (oxygen transmission rate <0.5cc/package/day);
• Traceability & branding: High-definition 8-color digital printing lines support variable data printing (batch numbers, anti-counterfeiting QR codes, shelf-life info) — while enabling custom brand designs (e.g., matte coatings, embossed logos) for 3-piece tinplate cans.

3. 3-Stage QC System for Food-Grade Safety

• Inbound: Tinplate is tested for corrosion resistance (salt spray test ≥48 hours) and thickness tolerance (±0.01mm);
• In-line: 3 inspection stations monitor can body strength (compression resistance ≥200N), seal tightness, and print adhesion (cross-cut test ≥4B);
• Final: 100% of finished food-grade tinplate cans undergo food contact safety testing (heavy metal migration <0.01mg/kg) before shipment — all batches comply with GB 4806.9 (China) and FDA 21 CFR 175.300 (US) standards.

4. Eco-Friendly Customisation & Scaled Cost Advantage

• Sustainability: We use water-based eco-inks (VOC emission <50g/L) and 100% recyclable tinplate (recycling rate ≥95%), helping clients reduce packaging carbon footprint by 22% (vs. plastic alternatives);
• Customisation: Flexible adjustments for can specs — e.g., square tinplate cans (for gift sets), easy-open tinplate cans (for snack packaging), or screw-top cans (for powdered food);
• Cost efficiency: With 50M annual production capacity + long-term supplier contracts, we offer 15-20% lower unit costs for 3-piece tinplate cans and bulk food packaging orders (vs. small-scale manufacturers).
