Explore our core catalog of food-contact compliant cans, easy-open ends, and specialized lids manufactured under ISO 9001 and FSSC 22000 certifications.
An authoritative analysis of modern metal packaging mechanics, material science, and global supply chain integration for commercial beverage and food processors.
In the high-speed canning industry, the physical reliability of metal containers depends directly on the metallurgical composition of the raw coil stock. Shanghai Friend Metals Technology Co., Ltd. utilizes specially engineered aluminum alloys tailored to the specific mechanical stresses of Drawing and Wall Ironing (DWI) as well as precision end stamping:
SEO Information Gain Insight: Every aluminum coil lot delivered to Shanghai Friend Metals is backed by an automated Spectro-chemical Mill Test Certificate (MTC). Thickness tolerances are strictly held to within ±0.002 mm, preventing line jams and micro-fractures on automated filling and seaming equipment.
To assist packaging engineers and procurement directors in qualifying technical compatibility, the table below outlines our standard alloy specifications, gauge tolerances, coating matrices, and target industry applications.

Strategic supply chain dynamics driving the global transition from rigid plastic and glass to infinitely recyclable aluminum container systems.
Aluminum is 100% infinitely recyclable without loss of structural or barrier properties. Over 75% of all aluminum ever produced worldwide remains in active commercial use today. Switching to aluminum container packaging drastically reduces Scope 1 and Scope 3 carbon emissions for international beverage conglomerates.
Compared to heavy, breakable glass bottles, lightweight aluminum cans offer up to a 40% improvement in container payload weight and spatial density during ocean transit. This lower tare weight reduces fuel consumption per liter delivered across global export routes.
Unlike PET plastic which permits slow oxygen ingress and UV light penetration, aluminum containers form an absolute, non-porous physical barrier against light, oxygen, and atmospheric moisture. This extends product shelf life up to 24 months without requiring chemical preservatives.
How our technical engineering team guarantees seamless integration with high-volume seaming machinery including Ferrum, Angelus, and Comaco.
Achieving a zero-leak hermetic seal at seaming speeds exceeding 1,500 cans per minute requires microscopic dimensional control of the end curl and flange. Shanghai Friend Metals performs rigorous double-seam teardown analysis on every production batch:
Direct interaction between liquid contents and aluminum metal causes galvanic corrosion, off-notes in flavor, and liner blistering. Our plant applies state-of-the-art electro-static liquid spray and coil lacquering systems:
De-risking international procurement through stringent quality control standards, regional regulatory approvals, and end-to-end export documentation.
All finished products are certified compliant with FDA 21 CFR 175.300 (USA), EU Regulation 1935/2004 (Europe), GB 4806.10 (China), and MERCOSUR food-contact standards. Migration testing reports and REACH/RoHS certificates accompany every bill of lading.
From raw aluminum coil ingot number down to the specific press line shift, every pallet shipped by Shanghai Friend Metals carries a unique QR-coded tracking matrix. Quality claims can be traced directly to mill chemical heat numbers within minutes.
To withstand multi-week oceanic freight and high coastal humidity, finished cans are shipped on heat-treated ISPM-15 wooden pallets with plastic top-frames, heavy kraft slip-sheets, and full-cover stretch-hood shrink wrapping.

How Shanghai Friend Metals is driving ultra-lightweighting, digital printing, and AI vision inspection into modern packaging production lines.
Through advanced finite element analysis (FEA), our R&D team is reducing can body sidewall thickness from 0.095 mm to 0.088 mm while preserving 1.0 kN minimum axial column strength, reducing material raw weight by 6%.
Eliminating minimum order constraints of traditional dry-offset printing plates. Direct-to-can HD digital printing lines enable dynamic variable-data printing, short-run craft promotions, and photorealistic 1200 DPI graphics.
Integrated neural-network camera systems scan 3,000 ends per minute, automatically rejecting micro-dents, flange contamination, liner voiding, or scratch flaws before final palletizing.
