Aluminum Alloy 3003 Food Grade (0.3mm × 1200mm with PE Coating) for Can Sealing Substrate

Product Description:

The Aluminum Alloy 3003 Food Grade, with a thickness of 0.3mm and a width of 1200mm, is a non-heat-treatable Al-Mn alloy (aluminum 96.7-99.0%, manganese 1.0-1.5%, trace iron, silicon, copper) in H14 or H24 temper, coated with a food-safe polyester (PE) layer, designed as a can sealing substrate for food and beverage cans. It offers excellent formability (elongation ~8-15%), moderate strength (tensile strength ~145-185 MPa), and superior corrosion resistance. The PE coating ensures compliance with food safety standards (e.g., FDA, EU regulations), preventing metal-food contact. Its lightweight nature (density ~2.73 g/cm³) reduces packaging weight, while its thermal conductivity (~121 W/m·K) and recyclability (recovery rate >95%) support sustainable, high-volume can production. The 1200mm width optimizes manufacturing for can lids and closures.
