What Is The Average Thickness of Aluminum Foil

Aluminum foil is a very commonly used packaging material. It has many advantages, such as lightness, softness, corrosion resistance, etc. Due to these advantages, aluminum foil has become the preferred material for food packaging. This article will introduce you to the thickness of aluminum foil and related knowledge.

What is the average thickness of aluminum foil

The thickness of aluminum foil can be adjusted according to different needs. Generally speaking, the average thickness of aluminum foil is between 0.006 mm and 0.2 mm. Its thickness can be classified according to different standards. For example, aluminum foil with a thickness of less than 0.01 mm is called ultra-thin aluminum foil, aluminum foil with a thickness between 0.01 mm and 0.1 mm is called ordinary aluminum foil, and aluminum foil with a thickness greater than 0.1 mm is called extra thick aluminum foil.

Applications

Food packaging: The flexibility and corrosion resistance of aluminum foil make it one of the best food packaging materials. Aluminum foil can keep food fresh and prevent the entry of oxygen and moisture. At the same time, it can also reduce packaging costs while reducing food waste.

Battery aluminum foil: Normally, the lithium-ion battery industry uses rolled aluminum foil as the positive electrode of the battery. The thickness of rolled foil ranges from 10 to 50 microns. Commonly used pure aluminum foil for lithium batteries has various alloy grades such as 1060, 1050, 1145, 1235, and has tempers such as -O, H14, -H24, -H22, and -H18.

Cooking: 50 micron aluminium foil is a kind of light gauge aluminum foil, and it is usually used in home packaging, cooking and baking. Standard household foil is about 0.01 mm, which can be used to heat food in the oven. The thickest heavy-duty aluminum foil is mainly used for high temperature needs, and its thickness is generally around 0.017 mm.

Issues to note

Although aluminum foil has many advantages, there are also some issues to note. Firstly, aluminum foil is easily scratched and torn, so you need to be careful not to contact with other sharp objects when using it. Secondly, aluminum foil is easy to deform at high temperatures, so you need to pay attention to using the appropriate thickness of aluminum foil when using it in the oven. Finally, due to the metal material of aluminum foil, there may be electrical conduction problems between aluminum foil sheets. Therefore, you need to pay special attention to the environment in which aluminum foil is used to avoid any safety issues.
