The difference between aluminum foil and tin foil

Aluminum foil, commonly known as tin foil paper and tin foil, is a tool made of flattened metal aluminum and is a sheet of thickness less than 0.2 mm processed by an aluminum foil rolling mill. The original tin foil was really made of tin. Because of its high heating temperature, tin foil began to embrittle when it was above 160 °C, which limited its use in food packaging. Aluminum foil paper starts to melt because it has a higher melting point and is heated above 660 ° C. It can be applied to ordinary barbecued foods and baked goods. Typically, aluminum foil used in paper bag beverage packaging and food packaging is only 6.5 microns thick. This thin aluminum layer is waterproof, savory, anti-bacterial and anti-fouling
Mainly used in kitchen cooking, holding food, or used to make some materials that can be easily cleaned. Most of the aluminum foil paper is shiny on one side and hoarse 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 the heat transfer. Since aluminum has a soft texture and good ductility, it has a silvery white luster. If the calendered sheet is smashed on offset paper with sodium silicate or the like to form an aluminum foil, printing can also be performed.
