Aluminum is widely used in the packaging industry, mainly due to its unique physical and chemical properties.
First, aluminum has good ductility and plasticity, and can be processed into packaging materials of various shapes and sizes, such as cans, boxes and foils.
Second, aluminum's corrosion resistance makes it excellent in food packaging, which can effectively protect food from environmental factors and extend the shelf life of food.
Benefits
- Ductility and plasticity: Aluminum can be easily processed into various shapes and sizes.
- Corrosion resistance: Effectively protect food and extend shelf life.
- Thermal conductivity: Make heating and cooling more efficient.
- Light blocking: Prevent food from deteriorating due to light.
- Non-toxicity: Ensure food safety.
- Composite materials: Combined with other materials such as plastic or cardboard to improve performance.
- Recyclability: High recycling rate, lower costs and less waste of resources.

Hard aluminum beverage cans
Hard aluminum usually refers to aluminum materials that have been heat treated or alloyed to increase their strength. In the manufacture of beverage cans, hard aluminum can not only improve the structural strength of the can body, but also ensure its stability during transportation and use.
Common carbonated beverages (cola, beer, etc.) mostly use hard aluminum beverage cans, because aluminum cans are not easily corroded by acid, the manufacturing cost is relatively low, and aluminum cans are easy to form and not easy to deform, which can ensure the pressure of carbon dioxide in soda and make the soda taste better.
