What Is The Thickness of Aluminum Foil In MM

What is the thickness of aluminum foil in mm, it is usually between 5 micrometers and 200 micrometers. In the packaging industry, common aluminium foil thickness specifications include 6μm, 9μm, 12μm, 15μm, 18μm and 20μm. Different thicknesses of aluminum foil are suitable for different packaging purposes. For example, 6μm aluminium foil is mainly used for moisture-proof packaging, 9μm and 12μm aluminium foil are mainly used for food and chemical packaging, while 15μm and 18μm aluminium foil are mainly used for explosion-proof packaging and military industries.

Common aluminium foil thickness mm include 0.01mm, 0.015mm, 0.02mm, 0.025mm, 0.03mm and other specifications. Different thicknesses correspond to different uses, including the following scenarios:

0.01mm aluminum foil: mainly used for food packaging, such as candy wrappers. Additionally, this type of aluminum foil is often used for cigarette packaging.

0.015mm aluminum foil: mainly used for making cigarette filters and rolling papers. Additionally, this type of aluminum foil thickness is often used for making battery casings.

0.02mm aluminum foil: mainly used for making packaging bags, moisture-proof bags, waterproof bags, etc. Additionally, this type of aluminum foil is often used for making wallpapers, decorative materials, etc.

0.025mm aluminum foil: mainly used for making cable insulation layers, packaging materials for electronic components, etc.

0.03mm aluminum foil: mainly used for making decorative materials, packaging materials, coatings, and sealing layers for construction materials.

In addition to the packaging industry, different industries have different requirements for the thickness specifications of aluminum foil. For example, in the construction industry, thicker aluminum foil is needed, such as the 18μm specification, while in the electronics industry, thinner aluminum foil is required to prevent electromagnetic interference, such as the 6μm and 7μm specifications. Additionally, during the manufacturing process of aluminum foil, processes like rolling and stretching are generally required, which can also affect the aluminum foil thickness in mm. Generally, controlling the thickness error of aluminum foil within ±5% is considered good, and if higher precision thickness control is required, advanced online thickness measurement systems and other technological means can be used. Overall, what is the thickness of aluminum foil in mm need to be determined based on specific application scenarios and process requirements.
