Aluminium blister foil

Buyers must prioritize alloy grade (typically 8011 or 8021) and temper (H18 for hard foil or O for soft foil). For pharmaceutical applications, the thickness usually ranges from 20 to 30 microns. It is critical to verify the Heat Seal Strength (typically ≥ 7.0 N/15mm) to ensure the integrity of the medicine's protection against moisture and oxygen.

The product must adhere to FDA (Food and Drug Administration) regulations or EU Directive 94/62/EC for packaging. For pharmaceutical use, ensure the supplier provides a Drug Master File (DMF) number and complies with GMP (Good Manufacturing Practice) standards. ISO 15378 is a specific quality management system for primary packaging materials for medicinal products that you should look for.

Request data on the Water Vapor Transmission Rate (WVTR) and Oxygen Transmission Rate (OTR); high-quality foil should offer near-zero permeability. Regarding printing, ensure the supplier uses non-toxic, heat-resistant inks that do not migrate into the product. Verify the OP (Over-Print) primer's resistance to high temperatures during the sealing process.

PTP (Push-Through-Packaging) foil is ideal for standard tablets and capsules, while Cold Form Foil (Alu-Alu) is necessary for highly sensitive drugs requiring a 100% barrier against light and moisture. For food, it is commonly used for yogurt lids or jam containers, requiring specific lacquer coatings compatible with the container material (e.g., PVC, PVDC, or PP).

Aluminium foil is highly sensitive to moisture. Ensure the supplier uses seaworthy packaging, including PE film wrapping, desiccant packets, and reinforced wooden crates. Specify that the rolls must be suspended in the box to prevent flat spots or edge damage during transit. For high-value orders, consider CIF terms to ensure the cargo is covered by insurance.

Focus on Total Cost of Ownership (TCO) rather than just the unit price. Negotiate based on LME (London Metal Exchange) aluminum price fluctuations to ensure fair market pricing. Request a pre-shipment inspection (PSI) by a third party like SGS or Intertek to verify the pinhole count and coating weight before the final payment is released.

Always use Secured Payment services provided by Made-in-China.com to protect your funds until delivery is confirmed. For the first order, it is advisable to use a Letter of Credit (L/C) or a staged T/T payment (e.g., 30% deposit, 70% against B/L copy). Avoid transferring money to private bank accounts; always verify that the account name matches the registered company name on the platform.

Check if your country imposes anti-dumping duties (ADD) or countervailing duties (CVD) on aluminium products originating from China. For example, the US and EU have specific tariffs on certain foil thicknesses. Work with a professional customs broker to classify the HS Code (typically 7607) correctly to avoid unexpected tax liabilities at the port of entry.
