What Is Thickness of Standard Aluminum Foil

 Choosing the thickness of aluminum foil mainly depends on the purpose for which it is used. Generally speaking, the thickness of standard aluminum foil is between 0.01mm and 0.2mm, which can be selected based on the following aspects:

1. Food packaging: It usually chooses thinner aluminum foil paper, about 0.01mm to 0.02mm. This kind of aluminum foil can effectively maintain the freshness of food and prevent contamination such as oxygen, water vapor, odor and bacteria.

Aluminum foil for food packaging Aluminum foil used for food packaging can be made into different processes according to different uses and the size of the packaged products. The processes of aluminum foil food packaging bags include three-side sealing bags, self-standing bags, zipper bags, self-standing zipper bags,etc.

2. Medical packaging: In the pharmaceutical industry, the thickness of aluminum foil paper is usually between 0.02mm and 0.04mm. This kind of aluminum foil paper can effectively isolate the effects of light, gas, humidity, etc. on medicines and ensure the quality of medicines.

The PTP aluminum foil is generally "hard" aluminum. In the United States, most pharmaceutical foils are around 25 microns thick, 25.4 µm to be precise. In Europe, the thickness of 20.0 µm is more common, and has a greater length advantage for the same weight of raw materials. In recent years, countries have been moving towards thinner 20.0 µm aluminum foil, regardless of market.

3. Industrial application: In the industrial field, it is necessary to use aluminum foil paper with a larger thickness, approximately between 0.04mm and 0.2mm, to better prevent corrosion, electromagnetic radiation and other effects.

Cable aluminum foil is a commonly used conductive material and is widely used in electric power, communications and other fields. The thickness of cable aluminum foil will directly affect its conductive properties and mechanical strength. According to different cable specifications and requirements, it is crucial to choose the appropriate thickness. Generally speaking, common cable aluminum foil thicknesses are available in various specifications such as 0.1mm, 0.15mm, and 0.2mm.

The use of aluminum foil in air conditioners is mainly to make heat-conducting fins for air conditioner heat exchangers. Currently, the alloys of aluminum foil for air conditioners include 3102, 8011 aluminum foil, etc. The commonly used states are H22/H24/H26, and the thickness range is 0.08~0.2 mm. There are certain differences in the strength and plasticity of each state. The specific choice of which alloy grade and which state of aluminum foil depends on the actual situation.

4. Cigarette packaging: The use of aluminum foil in the tobacco packaging industry is mainly the aluminum foil of cigarette lining paper. Aluminum foil lining paper is a composite paper of tissue paper and aluminum foil. The thickness of aluminum foil is 0.006mm to 0.007mm. Generally, 0.006mm thick aluminum foil is used. It is soft and has good extensibility.

Household aluminum foil: The thickness of household aluminum foil paper is 0.016mm (standard type) to 0.0245mm (Heavy duty). But there are also ones as thin as 5µm. Small rolls of household aluminum foil usually have thicknesses of 8mic, 9mic, 10mic, 11mic, 12mic, 14mic, 15mic, 16mic, 17mic and 18mic. Now, the width of large rolls of household aluminum foil can reach 1300mm. 0.2 mm thickness household aluminum foil is a common specification.
