Many customers do not know the differences between aluminum foil and tin foil. Zhengzhou Eming Aluminium Industry, as a professional aluminum foil manufacturer and supplier in China, will tell you the answer.

Aluminum foil is a thin sheet of aluminum that is less than 0.2 millimetres in thickness and can be used for various different things around the house. Aluminum sheets vary in thickness depending on what the foil is supposed to be used for. The most common foil that are available for commercial use are 0.016 millimetres thick, while heavy duty household foil is typically 0.024 millimetres. Aluminum foil is mostly used for packaging foods and other materials. Aluminum foil at home is used to keep the air from the fridge to contaminate the smell of the food, while others are used to packing the item. Aluminum foils are easy to tear and are often used with other materials such as plastic or paper wraps to ensure more sturdiness.

In addition to packaging, aluminum foil is also used for thermal insulation, cables and electronics because of its ability to conduct electricity. Aluminum foil is made by rolling aluminum sheet ingots casts, which are then re-rolled multiple times until the desired thickness is achieved. The sheets are applied heat but are cold-rolled to ensure it does not tear apart. When the thickness of the sheet is less than 0.025 mm, two layers are usually put together for the final pass and are later separated. The two sheets when separated results in one side of the foil sheet being shiny, while the other being matte. Aluminum foil sheets are used for storage, packaging, cooking and for many other household purposes.
Tin foil is a thin sheet of foil made from tin. This was the most common type of packaging and insulating material used before the World War II, following which aluminum became the cheapest material and went into mass production. Tin foil is actually much expensive and less durable compared to aluminum foil.

These days, tin foils are used in electrical capacitors. Tin foils are made using a similar process to aluminum foils; the foil is rolled from a thin leaf of tin. Tin foils are actually stiffer than aluminum foil and can leave a bitter taste to food wrapped in it.
