Metal packaging is very common in daily life. Packaging materials mainly include tinplate, galvanized sheet, chrome-plated plate and aluminum. Due to the good recyclability of aluminum, it is becoming more and more popular as a packaging material.
Aluminum alloy can be made into packaging boxes and cans of various shapes. Generally, 1060 aluminum sheet strips are used, which have good ductility, strong plasticity, are not easy to rust, wear and tear, and have no peculiar smell. They are commonly used raw materials for aluminum boxes. Moreover, the aluminum material is light in weight, and a layer of aluminum oxide film can be naturally formed on the surface, so the corrosion resistance is relatively good.
