What Are The Uses of 18 and 20 Micron Aluminum Foil

Aluminum foil is widely used in packaging, construction, electronics and other fields due to its excellent properties, such as good thermal conductivity, corrosion resistance, and recyclability. In particular, the demand for aluminum foil continues to increase in the food packaging and construction industries.

The demand for aluminum foil in the food packaging industry is growing, mainly because aluminum foil has good barrier properties, which can effectively prevent food from moisture, oxidation and bacterial invasion, thereby extending the shelf life of food.

Aluminum foil packaging can not only maintain the original flavor of food, but also prevent external contamination, so that food can maintain high quality during transportation and storage. In addition, aluminum foil is also opaque, which can effectively prevent the influence of light on food and is suitable for various foods that need to be stored away from light.

Aluminum foil is increasingly used for cooking a variety of foods because it is easy to use, disposable and conducts heat twice as fast as regular metal. As part of home cooking, aluminum foil is used for packaging and baking foods. 18 micron aluminium foil is a popular household aluminum foil thickness. Aluminum foil with a thickness of 15 μm and above has almost no pinholes; aluminum foil with a thickness of 12 μm and 8 μm is better than most plastic films in blocking water vapor.

In the construction industry, aluminum foil products are widely used for thermal insulation and moisture protection. Aluminum foil's ability to reflect thermal radiation makes it an excellent thermal insulator, often used in building roof, wall and floor structures. By adding aluminum foil to building materials, the heat loss of buildings can be significantly reduced and the frequency of use of air conditioning and heating equipment is reduced,,thereby reducing energy consumption and carbon emissions.

In the electronics industry, aluminum foil is widely used in the manufacture and packaging of electronic products due to its good conductivity and shielding properties. Aluminum foil can be used as a shielding material for cables to effectively prevent electromagnetic interference and improve the stability of signal transmission. In addition, aluminum foil can also be used as a battery pole material because of its excellent conductivity, which can increase the energy density and service life of the battery. 20 micron aluminium foil is often used for this use.
