Most of the aluminum foil is shiny on one side and matte on the other. Food foils can be wrapped on both sides of the foil. It is usually recommended to wrap the shiny surface to enhance heat transfer.
The original tin foil is really made of tin. The tin foil is softer than the aluminum foil. The wrapped food will have a little tin flavor. At the same time, the tin foil will not be heated because of its low melting point, or the heating temperature is high - if it is above 160 ° C, it will start to be brittle. It limits its use in food packaging, such as the need for grilled foods, and the use of tin foil when baking food. Since the aluminum foil has been heated, it has been heated to above 660 °C due to its high melting point.
It can be used for ordinary barbecued foods, baked goods, and even traditional chickens are wrapped in aluminum foil to keep them clean and clean while maintaining Original flavor. Therefore, after the aluminum price was lowered, the aluminum foil replaced the tin foil in daily life. However, since aluminum metal affects the development of the brain, the surface of the current aluminum foil is coated to avoid the release of metallic aluminum.
Aluminum foil paper is usually used for food storage (such as aluminum foil paper tray). It can be used to grill bean sprouts, potatoes, sweet potatoes, etc. when grilling, so as not to burn them. Sometimes used for decoration. Modern aluminum foil paper is made of aluminum and can also be used as an aluminum electrode for electrolysis. There are also hair stylists who use perm foil to perm for guests.
Some people also use aluminum foil to absorb the oil in the soup. Aluminum foil is also widely used for the barrier layer, heat exchange, and as an electrical conductor. Typically, the foil used in paper bag beverage packaging and food packaging is only 6.5 microns thick. This thin aluminum layer is water resistant, savory, anti-bacterial and anti-fouling. It is very common to hold food in aluminum foil trays. Although the aluminum foil tray is disposable, the composition is aluminum, which is less harmful to nature.
