Explore our tier-one product portfolio engineered for global canning lines, featuring ultra-low failure rates, optimal score depth integrity, and certified barrier protection.
As a global authority in rigid metal packaging manufacturing, our China-based smart manufacturing facilities bridge the gap between high-speed canning line efficiency and uncompromising barrier security.
The 65mm Easy Open End (EOE)—industry-coded as the 211# diameter (65.3mm nominal)—represents the absolute pinnacle of global rigid packaging standards. Widely deployed across Ready-to-Drink (RTD) beverages, infant nutrition powders, processed canned foods, and specialty chemical applications, the 65mm EOE requires ultra-precise metallurgical consistency. A fraction of a millimeter variance in score depth, tab rivet tightness, or compound lining placement can lead to micro-leaks, premature popping under thermal processing, or seam jams during high-speed closure operations (exceeding 1,200 cans per minute).
Our advanced production complex utilizes prime high-tensile 5182-H48 aluminium alloy coil and premium electrolytic tinplate (ETP), stamped on state-of-the-art Minster and Stolle multi-die conversion presses. By pairing microscopic mechanical accuracy with real-time AI optical inspection, we ensure every single 65mm end delivers zero-defect performance, optimal pop-and-pull mechanics, and total seal integrity over a multi-year shelf life.
Precision tooling guarantees seamless double-seaming compatibility across all major seamer machinery brands including Ferrum, Angelus, and Continental Can.

Our conversion dies hold residual score thickness to within 0.055mm ± 0.003mm. This eliminates premature score bursting during ocean transit vibrations while providing ultra-smooth consumer opening mechanics without razor-sharp feathering.
Specially formulated post-repair lacquers are electrostatically applied over the severed metal edge along the score line, preventing oxidation and acid attack even when packaging aggressive RTD beverages like cider, cola, or citrus juices.
Optimized curl height and width profiles guarantee consistent chuck engagement, preventing chuck slippage, flange cutting, or double-seam droops when operating at ultra-high canning line speeds.
How our integrated raw material slitting, stamping, and automated warehousing deliver unmatched cost efficiency and supply security for multinational buyers.
Unlike third-party conversion plants that purchase pre-slit or pre-coated sheets, our modern industrial complex maintains dedicated coil coating and high-speed tension-leveling coil slitting lines. By sourcing directly from top-tier aluminum smelters (using premium 3104 and 5182 alloys) and primary tinplate mills, we control the entire value chain.
This complete upstream control eliminates middleman markups, reduces raw material lead times by up to 14 days, and ensures micro-level uniformity in coating weight, substrate hardness, and surface lubrication.
Our lines are fitted with 100% online high-resolution camera vision systems. Every 65mm end is inspected at full production speed for tab alignment, compound bubble inclusions, micro-scratches, pinholes, and score line anomalies.
Defective pieces are pneumatically ejected within milliseconds. Furthermore, automated laser-marking options on master cartons ensure end-to-end batch traceability, connecting every pallet back to its specific coil heat number and production shift log.
Streamlining multinational procurement with flexible MOQs, customized buffer inventory arrangements, and sea-freight packaging engineering.
65mm easy open ends are packed in heavy-duty poly-sleeves inside corrugated master cartons or high-density wooden pallets, enclosed in vacuum-sealed moisture barrier film with desiccant packs to prevent transit oxidation during long ocean voyages.
For high-volume global beverage and food brands, we offer tailored VMI protocols and regional warehouse buffering, allowing filling facilities to maintain lean inventories while mitigating global supply chain disruptions.
Enhance brand presence right at the point of consumption with colored tabs (red, black, blue, gold), laser-etched promo codes under the tab, or custom logo embossing directly on the top shell surface.
Full global regulatory compliance paired with dedicated field application engineers (FAE) to optimize your on-site double-seaming setup.
Regulatory failure is non-negotiable in global food and beverage distribution. Our complete 65mm product lineup strictly adheres to global health and chemical exposure frameworks:
We don't just ship products; we integrate with your packaging engineers. Our dedicated technical service team provides detailed seaming specifications, including recommended first-operation and second-operation roll profiles, countersink depths, and seam thickness benchmarks.
In the event of line changes or seamer retrofits, our technical staff offers remote or on-site teardown evaluations and optical seam analysis to eliminate micro-leakage risks and ensure seamless line startup.
Staying ahead of regulatory shifts, circular economy targets, and smart interactive packaging innovations.
Driven by corporate ESG commitments and escalating freight fees, coil thickness is transitioning down from 0.23mm to ultra-thin 0.20mm shell gauges. Our engineering team utilizes advanced finite element analysis (FEA) to maintain structural buckle strength despite reduced material mass.
Connected packaging is rapidly accelerating. High-speed laser engraving systems apply high-density, anti-counterfeiting QR codes under the pull tab, unlocking direct-to-consumer promotional campaigns, loyalty rewards, and product authentication upon opening.
With stringent EU bans taking effect against microplastics and endocrine disruptors, water-based PVC-free compounds and non-bisphenol internal lacquers are becoming mandatory for export to Western markets.
Engineered options tailored specifically for different product viscosities, internal pressure loads, and shelf-life requirements.
