Aluminized film is widely used in packaging materials, and its main functions are antioxidant and thermal insulation. For example, aluminum foil bags and aluminum-plastic composite films in beverage, food and pharmaceutical packaging contain aluminum-plated films; aluminum-plated films are also widely used in the electronics industry. For example, in capacitors, inductors, and electronic devices, aluminum plating films can play the role of corrosion resistance, isolation, conductivity, and anti-jitter. In addition, it is often used for casing decoration of electronic products such as mobile phones and laptop computers.
