Yes. Our 8011 aluminum foil has passed FDA and EC 1935/2004 food-grade certifications. Heavy metal migration is far below international limits. It does not chemically react with acidic (tomatoes, citrus) or alkaline foods, does not produce metallic taste, and can be safely used in food packaging and cooking applications.

2. Can special specifications of 8011 aluminum foil be customized?

Yes. We support customization of thickness 0.006–0.2mm and width 50–2000mm. Surface treatments (embossing, coating, printing), temper (O / H18 / H22 / H24), and packaging methods can all be adjusted according to customer requirements. Minimum order quantity (MOQ) is 3 tons per specification. Delivery time for special customization is 10–20 days.

3. Are international certifications and test reports provided?

Yes. Each batch is supplied with a Certificate of Analysis (COA) and factory inspection report covering thickness, tensile strength, chemical composition, and heavy metal content. FDA test reports, REACH compliance statements, and SGS third-party test reports can also be provided upon request to ensure smooth customs clearance and use.

4. How are damages during transportation handled?

We use high-standard export packaging, with damage rate controlled below 0.1%. If damage is found after receipt, customers should provide damage photos, packing list, and bill of lading within 72 hours.

5. How should 8011 aluminum foil be selected compared with 1235 aluminum foil?

If high flexibility and deep drawing performance are required (such as complex-shaped food containers and flexible packaging), 1235 aluminum foil is recommended. If balanced strength and ductility with puncture resistance and high cost performance are required (such as household foil, blister packaging, and air conditioner fins), 8011 aluminum foil is the better choice. Samples can be provided for testing and comparison.

6. What are the payment terms and delivery cycles?

Payment Terms: Regular orders use 30% advance payment (T/T) + 70% balance payment (against copy of bill of lading). Long-term customers may negotiate L/C payment.
