What are the types of aluminum foil?

1. Flexible packaging aluminum foil

Flexible packaging is a bag-type container made of flexible composite packaging materials. The emergence of flexible packaging has greatly improved the level of mechanization and automation in the food and beverage industry, and accelerated the modernization and socialization of people's diet and life. In developed countries, flexible packaging has become one of the main packaging forms of food and beverages, replacing cans and bottles to a certain extent. In recent years, my country's flexible packaging market has also developed rapidly. So far, 10 aluminum foil lamination production lines have been introduced, and different processes such as dry lamination, hot melt lamination, and extrusion lamination can be adopted according to the different uses of flexible packaging. Flexible packaging not only has the functions of moisture-proof and fresh-keeping, but also can print various patterns and characters. It is an ideal material for modern commercial packaging. With the improvement of people's living standards, there is still a lot of room for development of flexible packaging aluminum foil.

2. the medicinal aluminum foil

Aluminum foil for pharmaceutical packaging mainly includes easy-open bottle caps for liquid preparations and injections and PTP aluminum foil for medicinal purposes. Because PTP aluminum foil has the advantages of moisture resistance, easy portability, safety and hygiene, it is widely used in the international pharmaceutical industry. my country has been using aluminum foil to package medicines since 1985. So far, the packaging aluminum foil only accounts for 20% of the pharmaceutical packaging materials. In recent years, the pharmaceutical foil market has developed rapidly. The proportion of applications in it is increasing.

3. Composite aluminum foil for automobiles

With the vigorous development of my country's automobile industry and the continuous improvement of the aluminumization rate of automobiles, the market demand for automobile foils has increased rapidly. There are two kinds of automobile foils, one is the composite foil for automobile air conditioners, and China's automobile air conditioners have been fully Aluminized, the annual demand for aluminum foil is 15,000 tons; the other is composite foil for automobile radiators, which is used to manufacture automobile water tank radiators, automobile condensers and evaporators. At present, the aluminization rate of automobile water tanks has reached 40%, and the annual demand The amount is about 3,000 tons.

4. Aluminum foil for electrolytic capacitors

The aluminum foil used in electrolytic capacitors is a corrosive material that works under polar conditions, and has high requirements on the structure of the aluminum foil. The aluminum foil used is divided into three types: cathode foil, with a thickness of 0.015mm to 0.06mm; high voltage foil, thickness The thickness is 0.065mm~0.1mm, and the aluminum foil is required to be produced with high-purity aluminum; the thickness of the low-voltage foil is 0.06mm~0.1mm.
