Wholesale Jumbo Rolls of 3003 / 3004 H32 Temper Aluminum Alloy Foil for Container Trays
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.
Why Are 3003 / 3004 Aluminum Alloys Suitable for Foil Containers and Trays?
1. Excellent Formability
3003 and 3004 aluminum alloys offer good ductility and can accommodate stamping and deep-drawing processes for containers of various depths and shapes.
2. Higher Strength
Compared with pure aluminum foil, 3xxx-series aluminum alloys provide better strength. This helps maintain structural rigidity and prevents serious deformation during transportation and handling.
3. Excellent Corrosion Resistance
3003 and 3004 offer good corrosion resistance and can meet the requirements of food packaging and general industrial packaging environments.
4. Good Heat Resistance
Aluminum has good heat resistance, making aluminum foil trays suitable for baking, heating, and certain frozen-food packaging applications.
5. Lightweight
Due to aluminum’s relatively low density, trays made from aluminum foil can effectively reduce overall packaging weight.
6. Superior Barrier Properties
Aluminum foil provides an effective barrier against light, moisture, oxygen, and certain external contaminants, offering enhanced protection for food products.
7. Food-Grade Safety
Our products strictly comply with FDA and national food-contact safety standards. The surface is degreased and evenly lubricated, allowing direct oiling and stamping. No harmful substances are released under high-temperature baking or freeze-thaw conditions.
8. Sustainable and Environmentally Friendly
Aluminum alloy can be recycled indefinitely, supporting the global green-packaging trend of replacing plastic with aluminum.
