Several Uses of Aluminum Foil

        At present, China's aluminum foil industry is developing at an astonishing speed, and its annual consumption of aluminum foil has jumped to second place, second only to the United States. However, in terms of per capita expenditure, China is still far behind some developed countries, which means that the use of aluminum foil still needs to be further developed. In fact, aluminum foil can be roughly divided into four types according to their different uses, which are applied in different situations. Next, let's take a look at the types and uses of aluminum foil together.

1、 Air conditioning foil
Air conditioning foil is used in the manufacturing of air conditioners and is a specialized manufacturing material for the heat exchanger, an important component of air conditioners. Air conditioning foil is an aluminum foil with fewer metallurgical defects and better ductility, therefore it has good formability during processing, and the aluminum foil material is very uniform. After anti-corrosion treatment and other processing, the air conditioning foil still has good surface properties. Generally speaking, the thickness of air conditioning foil is between 0.10-0.15 millimeters, but due to the increasingly sophisticated processing technology, the thickness of air conditioning foil tends to decrease. For example, the thickness of air conditioning foil produced in Japan can reach only 0.09 millimeters.

 
2、 Cigarette packaging foil
This type of aluminum foil can be said to be the closest to our daily life, and we can see the use of cigarette foil in cigarette packs. Especially in China, the domestic demand and export volume of cigarettes are large, so the cost of cigarette packaging foil is also very high. Generally speaking, 70% of cigarette foil is rolled aluminum foil, while the other 30% is sprayed foil. At present, there are several companies in China that produce cigarette foil that can reach world-class levels, but overall, there is still a certain gap between the average quality and the world level.

3、 Decorative foil
Due to its excellent coloring properties and good photothermal reflectivity, aluminum foil can also be used for decoration, packaging, and other purposes. Around the last century, decorative foil began to be used in the field of decoration and quickly became popular. Due to its moisture-proof, anti-corrosion, thermal insulation, and sound insulation properties, decorative foil is an excellent decoration material. In addition, aluminum foil packaging is exquisite and high-end, and has gradually become popular in recent years。

4、 Cable aluminum foil
Due to its sealing and shielding properties, aluminum foil can also be used as a protective cover for cables. However, before use, the aluminum foil still needs to undergo plastic coating processing. For cable aluminum foil, there are certain requirements in terms of length, mechanical properties, and sealing performance, especially for the length requirements, which are very strict.

        From the current situation, due to the wide application of aluminum foil and its important role in various important industries, China's aluminum foil industry has a good development prospect.
