Aluminum foil is made of electrolytic aluminum or aluminum alloy plate with purity of 99.3% ~ 99.9%, and its thickness is generally below 0.20 mm.

Due to the different degree of heat treatment after calendering, aluminum foil can be divided into soft and hard.

Because aluminum foil has a series of good properties, its application range is very wide. From a global perspective, it is mainly used in packaging, electricity and construction.

Among them, the demand for packaging is the largest. The packaging with the largest consumption of aluminum foil in China accounts for more than 50%, followed by electrolytic capacitor industry, accounting for about 15%, and the third is soft packaging and other packaging industries, accounting for about 15%.
