  • Lightweight: Aluminum foil is very lightweight because aluminium metal itself is a lightweight material. This makes aluminum foil an ideal material during packaging and shipping.
  • Good sealing: The surface of aluminum foil is very smooth, which can effectively prevent the penetration of oxygen, water vapor and other gases, so it can maintain the freshness and quality of food and medicine.
  • Corrosion resistance: Aluminum foil is very corrosion resistant because aluminium metal itself has good corrosion resistance. This makes aluminum foil an ideal material when packaging chemicals and corrosive substances.
  • Good conductivity: Aluminum foil has good conductivity, so it is widely used in the electronics industry, such as used as electrodes in batteries and capacitors.
  • Good plasticity: aluminum foil is very soft and flexible, and can be easily wrapped around various shapes of items.
  • High recyclability: Aluminum foil can be reused, recycled and reused, so it has less impact on the environment and saves resources.
