Aluminium foil

Selecting the right alloy is critical for performance. For food packaging and household use, Alloy 8011 is the industry standard due to its high tensile strength. For pharmaceutical packaging (blister packs), Alloy 8021 or 8079 is preferred for superior barrier properties. Ensure the temper is 'O' (soft) for wrapping or 'H' (hard) for rigid containers.

Buyers must verify thickness tolerance (usually ±5%) and width precision. For food-grade foil, the pinhole count is a vital metric; high-quality foil should have near-zero pinholes to prevent moisture and oxygen ingress. Also, confirm the surface cleanliness (Oil Grade A) to ensure no chemical residue remains from the rolling process.

For the US market, FDA 21 CFR 178.3910 compliance is essential. For the EU, products must meet EC No. 1935/2004 and EN 602 standards. Always request SGS or TUV test reports confirming the material is free from heavy metals and safe for direct food contact.

Aluminium is a commodity; prices fluctuate based on the LME (London Metal Exchange) index. To save costs, negotiate a 'Fabrication Charge + LME Price' model. Purchasing in Full Container Loads (FCL) significantly reduces the risk of edge damage during transit and lowers the per-ton shipping cost.

The primary risk is oxidation caused by moisture (white rust). Ensure the supplier uses sea-worthy packaging, including plastic film wrapping, desiccant silica gel, and strong wooden cases. For long-distance sea freight, suspended packaging (where the roll does not touch the box bottom) is recommended to prevent flat spots or dented edges.

Before placing a large order, conduct a factory audit or hire a third-party inspector to verify the rolling mills and annealing equipment. Always request a Pre-Shipment Inspection (PSI) to check the weight and surface quality.

Be aware that several countries, including the US, EU, and India, have imposed anti-dumping (AD) and countervailing duties (CVD) on certain aluminium foil products originating from specific regions. Always check your local HS Code (typically 760711) regulations to calculate the total landed cost accurately.
