Direct factory supply featuring fully certified food-grade aluminum cans, specialized powder packaging closures, freeze-resistant lids, and high-tensile 3104 alloy coils.
As a global top-tier OEM/ODM aluminum easy open ends factory, our engineering architecture is founded upon rigorous metallurgical control, nanometer-level coating precision, and flawless double-seam integrities.
Our easy open ends are cold-rolled from premium 5182-H48 aluminum alloy coil engineered specifically for high-stress shell forming. Featuring an optimized magnesium-manganese alloy balance, our lids deliver superior buckle resistance up to 6.2 bar (90 psi), satisfying demanding thermal processing and internal carbonation pressures.
Micro-precision scoring depth is controlled within a strictly enforced ±0.0025 mm (2.5 microns) tolerance. This precise residual thickness balance ensures effortless consumer opening (pop force < 22N, pull force < 35N) while completely eliminating spontaneous micro-fractures during high-speed freight or vacuum preservation.
Internal protection utilizes state-of-the-art BPA-Non-Intent (BPA-NI) Organosol and Modified Polyester coatings. Formulated for neutral taste impact and high acid resistance (pH 2.5–8.0), each batch undergoes 100% enamel rater testing (<2.0 mA porosity threshold) to ensure zero aluminum migration into aggressive food matrices.
Combining multi-gigawatt clean energy integration, fully automated high-speed conversion presses, and IoT-driven ERP ecosystems to provide maximum cost efficiency and uninterrupted international delivery.
Our manufacturing facility features multiple imported Stolle and Minster high-speed conversion presses operating at up to 3,000 ends per minute per line. Closed-loop servo feeders maintain dynamic stroke stability, delivering unmatched dimensional uniformity across millions of units.
Integrated 4K high-resolution optical inspection cameras scrutinize every single lid at 360 degrees. The system automatically detects micro-pinholes, tab alignment deviations, curl deformation, and lacquer scratches in real-time, instantly ejecting non-compliant parts with zero margin for human error.
Situated near China's largest deep-water ocean ports (Shanghai / Ningbo), our mega-warehouse maintains a permanent buffer stock of 50,000+ metric tons of primary coil and standard lids (200#, 202#, 307#, 401#, 502#), guaranteeing rapid shipping container dispatch within 7–10 days.
Tailored technical configurations across various global consumer end-markets. Custom sealants, gauge thicknesses, and tab ergonomics built to match specific filling environment stresses.
Optimized for high internal pressures (up to 6.2 bar). Features 202# SOT (Stay-On Tab) and RPT (Ring Pull Tab) ends paired with retortable, pasteurization-stable water-based internal lacquers. Compatible with high-speed filling lines running at up to 1,500 cans/minute with zero feathering or flange distortion.
Large-diameter closures including 401# (99mm) and 502# (127mm) featuring Peel-Off Membrane (POF) and Transparent Window Lids. Engineered for 100% hermetic vacuum holding, ultra-low oxygen transmission rates (<0.5 cm³/m²/day), and child-safe smooth edge contouring after removal.
Specially engineered 209# Freeze-Resistant & Non-Magnetic 209FA# Easy Open Ends. Outfitted with crack-resistant plastisol compound sealants that maintain flexibility and vacuum seal integrity in deep-freeze environments (-30°C to -40°C) and sterile pharmaceutical cleanrooms.
Comprehensive dimensional parameter mapping to support high-speed seamer integration (Angelus, Ferrum, Somme, Comaco). Custom curl diameter, countersink depth, and compound weight tolerances.

Guaranteed compliance with international food contact standards backed by on-site technical field service engineers for seamless seamer calibration.
All packaging components undergo continuous migration testing audited by SGS and Intertek. Fully certified compliant with US FDA 21 CFR 175.300, EU Regulation 1935/2004, EU 10/2011, REACH, RoHS, and GB 4806.10 standard protocols for direct food contact safety.
Our senior packaging engineers provide remote and on-site field technical support. We assist your plant setup in adjusting chuck and roll profiles, optimizing seam thickness, countersink depth, and body hook overlap percentage to achieve zero-defect double seam hermetic seals.
Every export wooden pallet and corrugated container is assigned a unique DataMatrix barcode. This digital twin records master coil batch heat numbers, stamping press line ID, lacquer application operator, optical defect logs, and final QC release sign-offs for transparent supply chain audits.
Pioneering lightweight metallurgy, circular zero-waste manufacturing, bio-based barrier coatings, and tethered tab mechanisms aligned with global environmental mandates.
Our R&D metallurgical team is pioneering the next generation of 0.20mm and 0.19mm down-gauged shell stock. Utilizing modified alloy tempering processes, this initiative yields a 6.5% reduction in total aluminum usage per end without sacrificing structural column strength or pressure thresholds.
To support strict European Union Single-Use Plastics (SUP) directives and circular economy goals, our design team has patented 100% tethered pull-ring opening systems. This ensures the tab remains permanently anchored to the shell after opening, eliminating litter and increasing aluminum recycling retention rates.
Eliminating petroleum-derived lacquers, our future-proof barrier coating uses 100% bio-sourced plant resin lacquers. Tested for high heat resistance during retort processing (>121°C for 30 min), this green technology achieves zero carbon footprint coating application with zero toxic emissions.
