Aluminum foil is a hot stamping material that is directly rolled into thin sheets from metallic aluminum. Because aluminum has a soft texture, good ductility, and a silvery white luster, if the calendered sheet is mounted on offset paper with sodium silicate and other substances to make aluminum foil, it can also be printed. However, aluminum foil itself is easy to oxidize and darken in color, and will fade when rubbed or touched, so it is not suitable for hot stamping of long-term preservation of book covers, etc.
The main purpose:
It is widely used in food, beverages, cigarettes, medicines, photographic plates, household necessities, etc., and is usually used as packaging materials; electrolytic capacitor materials; thermal insulation materials for buildings, vehicles, ships, houses, etc.; and can also be used as decorative gold and silver wire, Wallpapers, various types of stationery, printed matter and decorative trademarks for light industrial products, etc.
Aluminum foil, also known as aluminum foil, commonly known as tin foil, tinfoil, etc., is made of flattened aluminum. It is mainly used in the kitchen for cooking, holding food, or for making some materials that can be easily cleaned. Aluminum foil is used in large quantities around the world to protect and package food, cosmetics and chemicals. Most aluminum foils are shiny on one side and gray on the other. Aluminum foil paper for food can be used to wrap food on both sides. It is usually recommended to wrap food on the glossy side to improve the heat conduction effect.
Aluminum foil is usually used to hold food (such as aluminum foil plates). It is used to wrap bean sprouts, potatoes, sweet potatoes, etc. for grilling to prevent them from burning. Sometimes used for decoration. Modern aluminum foil paper is made of aluminum and can also be used as aluminum electrodes for electrolysis. There are also hairstylists who use aluminum foil to perm customers' hair. Some people also use aluminum foil to absorb the oil in the soup. Aluminum foil is also widely used as an isolation layer, heat exchanger, and as an electrical conductor. Usually, the thickness of aluminum foil used in paper beverage packaging and food packaging bags is only 6.5 microns. This thin layer of aluminum repels water, preserves flavor, and resists bacteria and stains.
