Blister aluminium foil price

The price is primarily driven by the alloy grade (usually 8011 or 8021) and the temper (H18 for hard foil or O for soft foil). Buyers must specify the thickness, typically ranging from 20 to 30 microns, and the heat-seal lacquer coating weight (usually 4-6 gsm). High-quality foil must ensure a pinhole rate of zero to maintain the barrier integrity required for pharmaceutical packaging.

Suppliers must provide US FDA DMF (Drug Master File) registration or EU REACH compliance. It is critical to verify ISO 15378 certification, which specifically addresses primary packaging materials for medicinal products, ensuring the manufacturer follows GMP (Good Manufacturing Practices).

For standard blister packs, Hard Temper (H18) foil is required to allow the tablet to be pushed through easily. The bursting strength must be balanced; if the foil is too thick or the temper is too soft, the end-user will struggle to access the medication. Conversely, for Child-Resistant (CR) packaging, a laminate of PET/Alu/Paper is often used to increase puncture resistance.

Custom printing using rotogravure or UV flexographic printing adds to the cost. Buyers should account for cylinder engraving fees for new designs. To optimize costs, ensure the supplier uses non-toxic, heat-resistant inks that do not smudge during the high-temperature heat-sealing process on the blister machine.

Aluminium is a commodity with fluctuating prices on the LME (London Metal Exchange). Professional buyers should negotiate a formula-based pricing model (LME base price + conversion margin) or use short-term validity quotes (typically 3-7 days) to lock in rates. For large-scale annual needs, consider hedging strategies or signing a framework agreement with a fixed conversion fee.

Aluminium foil is highly sensitive to moisture and oxidation. Ensure the supplier uses sea-worthy packaging, including plastic film wrapping, desiccant packs, and strong wooden crates (fumigated per ISPM 15). During transit, avoid 'LCL' (Less than Container Load) if possible to prevent physical damage from other cargo; FCL (Full Container Load) is preferred for maintaining roll roundness and preventing edge dents.

Utilize Trade Assurance services on Made-in-China.com to protect your funds. Before the final balance payment, mandate a third-party inspection (such as SGS or Intertek) to perform a pinhole test, coating thickness measurement, and heat-seal strength test. Never skip the sample validation stage, as the foil must be compatible with your specific blister packing machine's heat and pressure settings.

Focus on Total Volume Commitment rather than single-order size to secure 'VIP' pricing. Ask for transparency in the 'Alu + Processing' cost breakdown. Suppliers are more likely to offer discounts if you provide clear technical drawings and artwork upfront, reducing their internal pre-production engineering costs.
