1. Tin paper is a kind of film-like metal paper coated or pasted with silver, mostly silvery white, and the metal component is actually aluminum, not tin. Aluminum foil paper, also called tin foil in Hong Kong, is a thin sheet with a thickness of less than 0.2 mm. Most aluminum foil paper has a shiny side and a dull side. Mainly used for packaging food, medicine, cosmetics and other chemical products.
2. Aluminum foil paper is usually used to hold food (such as aluminum foil paper plates). When used for barbecue, bean sprouts, potatoes, sweet potatoes and so on can be wrapped. In order to barbecue and prevent them from burning. Sometimes it is used for decoration. Modern aluminum foil paper is made of aluminum and can also be used as aluminum electrode for electrolysis. There are also hair stylists who burn guests with aluminum foil paper. Some people also use aluminum foil to absorb the oil in the soup. Aluminum foil paper is also widely used for insulation, heat exchange and as a conductor. Usually, the thickness of aluminum foil used in paper-wrapped beverage packaging and food packaging bags is only 6.5 microns. This thin aluminum layer can be waterproof, fresh-keeping, antibacterial and pollution-proof. It is common to hold food in aluminum foil trays. Although the aluminum foil tray is disposable, it is made of aluminum, which is less harmful to nature.
3. The original tin foil is really made of tin, which is softer than aluminum foil and has a little tin smell when wrapping food. At the same time, because of its low melting point, it can't be heated, or the heating temperature is high-for example, it will become brittle when it reaches 160℃-which limits its use in food packaging. If you need to barbecue food, you can't use tin foil when baking food. Since the advent of aluminum foil paper, because of its high melting point, it began to melt when heated above 660℃. Can be suitable for ordinary barbecue food, baked food and even traditional beggar chicken to be wrapped and baked with aluminum foil paper, and is clean and hygienic while maintaining the original flavor. Therefore, after the price of aluminum decreased, aluminum foil replaced tin foil in daily life. However, due to the influence of aluminum metal on brain development, the surface of aluminum foil is coated at present to avoid the release of aluminum metal.
