In the food industry, aluminum foil is used as a food packaging material, such as aluminum foil boxes, aluminum foil bags, etc., to maintain the freshness and taste of food. In the construction industry, aluminum foil is used as insulation material, such as aluminum foil insulation board, aluminum foil insulation blanket, etc., to improve the insulation performance of buildings. In the aerospace field, aluminum foil is used to make the shells and structural components of aircraft, rockets, and other aircraft due to its lightweight and high-strength characteristics.

Aluminum foil, as a lightweight and flexible metal foil, plays an important role in daily life and industrial production due to its unique physical and chemical properties. It is made of high-purity aluminum through rolling processing, with excellent thermal conductivity, conductivity, corrosion resistance, and recyclability. Next, we will delve into the characteristics, applications, and future development of aluminum foil.
