Explore our certified range of freeze-resistant, airtight, and high-sterilization metal lids engineered for high-speed automated canning lines.
An authoritative technical review on alloy selection, double-seam precision, coating chemistry, and high-speed canning line optimization for global buyers.
Utilizing high-tensile AA5182-H48 aluminum alloy for shell stock combined with AA5052-H32 for tab stock. Provides superior buckle resistance under high internal pressures up to 6.2 bar (90 PSI).
State-of-the-art organosol, acrylic, and BPA-NI (Bisphenol A Non-Intent) interior lacquers tested against aggressive carbonated beverages, acidic juices, and fatty dry milk powders.
Sub-micron scoring depth tolerance (±0.002 mm) guarantees consistent pop-and-pull opening force (<30 N) while preventing premature feathering and micro-leakage during shipping.
Comprehensive overview of standardized Easy Open End profiles manufactured according to international ISO and ISO/FSSC 22000 standards.

China's modern metal packaging industry offers significant structural supply advantages. By integrating raw aluminum smelting, precision cold-rolling, chemical lacquering, and high-speed multi-die stamping in close geographical proximity, our manufacturing facilities achieve incredible speed and cost efficiencies.
For international buyers, this means access to high-speed Minster and Stolle press lines operating at up to 3,000 ends per minute, paired with online High-Resolution Optical Inspection systems that eliminate microscopic defects in real time.
Enterprise buyers require supply security, seam compatibility, and zero line-stoppage risk. Our factory supports global procurement teams through:
Bridging global manufacturing prowess with regional regulatory mandates and circular economy goals.
Our easy open lids fully conform to strict global food-contact standards, including FDA 21 CFR 175.300, EU Regulation 1935/2004, Commission Regulation (EU) No 10/2011, and China GB 4806.10. Complete migration test reports accompany every shipment.
Support for regional market requirements including custom top-shell printing, multi-color tab anodization, laser-etched promotional codes underneath tabs, and multi-language warning labels for export markets.
Aluminum is infinitely recyclable. We actively drive lightweighting initiatives—reducing end thickness from 0.224mm to 0.208mm—significantly reducing carbon footprint without sacrificing structural pressure integrity.
Our easy open ends are optimized for various extreme processing conditions across different beverage and food sub-sectors:
