What Is Aluminium Foil Thickness

The aluminum foil thickness is usually below 0.2 mm. It can be divided into light gauge aluminum foil and heavy duty aluminum foil. The light gauge foil is less than 0.1mm, usually 0.0004 thick and 0.0007 thick. It is widely used in beverage packaging, flexible packaging, cigarette packaging, capacitors and construction and other fields.

Most aluminum foils belong to the light gauge foil like medicine packaging foil, tape foil, food packaging foil,electronic foil. How to choose aluminum foil thickness? It is necessary to determine the use of the light gauge foils, as well as the requirements for specifications, surface quality and performance of aluminum foil. For example, the aluminum foil used in architectural decoration needs to have a smooth and beautiful surface, so it is best to have no oil stains and water spots.

As the name implies, heavy duty aluminum foil is thicker and sturdier than regular aluminum foil. It’s tough enough to stand up to high heat, heavy food items, and long-term storage in the freezer. The heavy duty aluminum foil thickness is between 0.008-0.001 thick.

How to measure the values

Use a ruler to measure the length and width of the aluminum foil in centimeters. Crumple the piece of foil into a small ball or fold it into a small shape and place it on a milligram balance to find the weight. Records the values on a sheet of paper or data table.

Control the thickness difference of aluminum foil

It is a feature of aluminum foil rolling that thickness deviation is difficult to control. The thickness difference of 3% is not difficult to control in the production of sheet and strip, but it is more difficult to control in the production of heavy duty aluminum foil.

As the thickness of the aluminum foil decreases, its trace conditions can affect it, such as temperature, oil film, and oil and gas concentration. Haomei aluminum foil production is equipped with Honeywell thickness gauge to ensure the control of outlet thickness.
