Explore our top-tier precision-drawn 330ml/200ml cans, 401#/5182# lacquered coils, and rust-proof easy-open closure systems tested under stringent double-seam teardown protocols.
The global market for high-performance metal packaging demands absolute structural integrity, chemical inertness, and visual distinction. As a primary manufacturer based in Shanghai, Shanghai Friend Metals Technology Co., Ltd. integrates state-of-the-art metallurgical processing with specialized gold-anodized and lacquered aluminium foil solutions. Gold aluminium foil and its derivative container components (such as 200#, 202#, 300#, 401#, and 502# easy-open ends) are not merely visual branding statements—they represent advanced multi-layer barrier systems designed to prevent gas permeation, light degradation, and chemical oxidation.
Our core manufacturing process leverages high-purity aluminum alloys, specifically 3104-H19 for drawn-and-wall-ironed (DWI) can bodies, 5182-H48 for high-strain easy-open shell stock, and 8011-O/H14 for flexible gold-coated sealing foils. The gold finish is achieved through specialized organosol or epoxyphenolic golden lacquers, thermal-cured under micro-processor-controlled oven lines to guarantee zero micro-porosity and complete BPA-Non-Intent (BPA-NI) compliance.
Zero moisture vapor transmission rate (MVTR) and 100% UV-light blockage. Protects sensitive infant milk powder, pharmaceuticals, and active food ingredients from oxidation.
Precision-controlled earing ratios (<1.2%) and tensile strengths exceeding 290 MPa. Prevents flange cracking during high-speed double seaming up to 1,200 cpm.
Formulated to endure thermal processing up to 121°C for 45 minutes under autoclave conditions without gold lacquer blistering, color shift, or adhesion loss.

Industrial procurement of gold aluminium foil and container lids varies significantly by climate, logistics conditions, and consumer intent. Shanghai Friend Metals tailors coating recipes, shell profiles, and packaging specs to resolve localized operational friction.
Challenge: Extreme ambient temperatures (45°C+) and coastal salt air accelerate oxidation and liner degradation in milk powder and coffee cans.
Engineering Solution: Application of anti-corrosive, salt-spray-tested gold epoxyphenolic lacquers on 401# and 502# ends, combined with heavy desiccant-jacketed export palletizing.
Challenge: High demand for premium aesthetic differentiation in sleek/slim craft soda, RTD cocktails, and energy drinks.
Engineering Solution: 202# SOT and RPT ends with custom deep-gold anodized tabs and matte gold body varnishes, fully matching high-speed US filling lines.
Challenge: Demanding legislation regarding bisphenol migration limits (EU 2024/1987) and strict metal circularity targets.
Engineering Solution: 100% BPA-NI internal protective coatings certified by independent laboratories (SGS/TÜV), coupled with high-recycled-content 3104/5182 coil alloys.
Challenge: High relative humidity causing condensation rust on tinplate lid edges during un-airconditioned maritime transit.
Engineering Solution: Transitioning clients to rust-proof 300# and 307# gold aluminium easy-open lids with full-curl compound gaskets.
