Haomei Aluminum’s aluminum foil for food container use 3003 8011 are the preferred products for the food container industry, strictly adhering to international food-grade standards and suitable for various food container processing scenarios. Focusing on the core specifications, key production technologies, and practical advantages of these aluminum foils, and combining our experience in mass production and global export, we provide customers with accurate and professional product references to help them efficiently select the right products and improve processing efficiency.
Regarding specifications, considering export market demands and the forming characteristics of food containers, our 3003 and 8011 aluminum foils strictly follow international food-grade standards, achieving precise compatibility of core specifications. 3003 aluminum foil thickness is controlled between 0.03-0.2mm, with a tolerance accurate to ±0.002mm. Width ranges from 100-2000mm and can be cut to order. The inner core uses standard 405/508mm specifications, suitable for various food container stamping equipment. 8011 aluminum foil has the same thickness range as 3003, focusing on optimized surface roughness, with Ra value controlled between 0.2-0.5μm, balancing formability and printability. In practice, for export markets such as the EU, Japan, and South Korea, we additionally control the roll sheet pyramid shape to ≤1.0mm and the layer misalignment to ≤0.5mm to avoid material jamming and wrinkling issues during subsequent customer processing. This is a core detail advantage of our export products.
Regarding core technologies, our company focuses on “food-grade safety” and optimizes processes based on years of production experience.
Alloy composition control is crucial: 3003 aluminum foil strictly controls manganese content between 0.9% and 1.1%, improving corrosion resistance and moderate strength, and eliminating excessive impurities; 8011 aluminum foil optimizes the iron and lithium trace element ratio, reducing the risk of aluminum migration and complying with FDA 21 CFR 177.1390 and GB 4806.9-2023 standards.
The rolling process uses a fully automated cold rolling mill, controlling the rolling speed at 300-500 m/min, combined with homogeneous annealing at 500-600℃ to ensure the foil surface is free of pinholes (density <50 pinholes/m²) and oxidation spots. Surface treatment uses a chromium-free passivation process, with residual amounts <10 μg/dm², and passes ATP swab testing (<10 RLU/cm²), mitigating food contamination risks from the source and making it suitable for contact with acidic and oily foods.
In terms of practical advantages, the 3003 and 8011 aluminum foil for food containers each have their own focus, catering to different customer needs. 3003 aluminum foil boasts a tensile strength of 90-140 MPa, an elongation of 10%-15%, and a temperature resistance range of -20℃ to 120℃. It is suitable for reusable food containers such as aluminum foil lunch boxes and insulated boxes. Its excellent corrosion resistance and weldability make it suitable for mass production stamping. Our food container aluminium foil exported to Europe and America uses 3003 alloy, with customer feedback indicating a forming pass rate of over 99.5%. 8011 aluminum foil offers superior plasticity and outstanding barrier properties, with a water vapor permeability of <0.1 g/m²/day. It is suitable for disposable food containers such as takeout containers and baking trays, offering better cost-effectiveness. Its surface is also suitable for food-grade printing, meeting customer brand customization needs. Currently, it is exported in bulk to Southeast Asia and the Middle East.
Leveraging our mature export supply chain, aluminum foil for food container use 3003 8011 have passed international certifications such as SGS and LFGB. Each batch of products comes with a complete test report covering six core indicators, including migration testing and tensile strength. In production, we achieve full traceability, from raw material intake to finished product delivery, precisely controlling every step to ensure food contact safety while also considering customer processing efficiency. Haomei Aluminum always focuses on practical technical expertise, making 3003 and 8011 aluminum foil the preferred solution for food container customers worldwide.
