          Jun 15, 2024Leave a message

          Aluminum foil is a hot stamping material that is directly rolled into thin sheets from metal aluminum. Its hot stamping effect is similar to that of pure silver foil, so it is also called fake silver foil. Aluminum foil has the characteristics of soft texture, good ductility, and a silvery-white luster, which makes it suitable for a variety of purposes. 12

          Classification of aluminum foil:

          Classification by thickness. The thickness of aluminum foil can be very thin. In the industry, aluminum products with a thickness of less than 0.2mm are usually called aluminum foil. Specific classifications include thick foil (0.1-0.2mm), single zero foil (0.Olmm and less than 0.1mm), and double zero foil (thickness less than 0.0075mm). 45
          Classification by shape. Aluminum foil can be in roll or sheet form, and deep-processed raw materials are mostly supplied in roll form. 6
          Classification by state. Aluminum foil can be divided into hard foil, semi-hard foil and soft foil, which are suitable for different processing and treatment processes.
          Classification by surface state. Aluminum foil can be single-sided or double-sided, depending on the rolling and subsequent treatment process.
          Classification by processing state. Aluminum foil can be processed by embossing, laminating, coating, etc. to meet specific usage requirements.
          Application areas:

          Packaging materials. Aluminum foil is widely used in the packaging of food, beverages, medicines, etc. due to its moisture-proof, airtight, light-shielding, abrasion-resistant, and fragrance-retaining properties. 7
          Construction and insulation. Aluminum foil is used as insulation material for buildings, vehicles, ships, houses, etc.
          Decoration and printing. Aluminum foil is easy to process into beautiful patterns and patterns of various colors due to its elegant silver-white luster. It is often used for decorative gold and silver threads, wallpapers, and various stationery prints and decorative trademarks of light industrial products.
          Other fields. Aluminum foil is also used in electrolytic capacitor materials, aerospace, medicine, home appliances, and other fields.
