In food processing, catering delivery, baking, airline catering, and disposable packaging industries, aluminum foil containers and trays are widely used for food and industrial packaging. Their advantages include light weight, heat resistance, corrosion resistance, excellent barrier properties, recyclability, and high processing efficiency.
We specialize in supplying industrial packaging jumbo rolls of 3003 / 3004 H32 temper aluminum alloy foil. These products are specifically designed for high-strength, deep-drawing container trays and food packaging boxes, helping customers reduce production costs and improve finished-product quality.
Both 3003 and 3004 belong to the Al-Mn series of rust-proof aluminum alloys, one of the most widely used alloy families. Neither alloy can be strengthened by heat treatment; their mechanical properties are mainly improved through cold working (rolling). The H32 temper indicates that the material has been strain-hardened and then stabilized through low-temperature annealing.
