Aug. 26, 2020

1. Composite aluminum foil for automobiles

With the vigorous development of China's automobile industry and the continuous increase of automobile albuminization rate, the market demand for automobile foils has increased rapidly. There are two kinds of automobile aluminum foils. One is the composite foil for automobile air conditioners. Aluminization, the annual demand for aluminum foil reaches 15,000 tons; the other is the composite foil for automobile radiators, which is used to manufacture automobile water tank radiators, automobile condensers, and evaporators. The current automobile water tank aluminization rate reaches 40%, and the annual demand The volume is about 3 million tons.

2. Medicinal aluminum foil

Pharmaceutical packaging aluminum foil mainly includes liquids, easy-open caps for injections, and medicinal PTP aluminum foil. PTP aluminum foil is widely used in the international pharmaceutical industry because of its moisture-proof, easy-to-carry, safe, and hygienic advantages. China began to use aluminum foil for packaging medicines in 1985. So far, packaging aluminum foil only accounts for 20% of pharmaceutical packaging materials. In recent years, the pharmaceutical foil market has developed rapidly. On the one hand, the rapid development of the pharmaceutical market, but mainly because 20% of the aluminum foil in the pharmaceutical packaging application proportion is increasing.

3. 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 mechanization and automation level of the food and beverage industry and has accelerated the modernization and socialization of people's dietary life. In developed countries, flexible packaging has become one of the main packaging forms for food and beverages, replacing canned and bottled packaging within a certain range. In recent years, my country's flexible packaging market has also developed rapidly. So far, 10 aluminum foil composite production lines have been introduced, and different processes such as dry composite, hot-melt composite, and extrusion composite can be used according to different uses of flexible packaging. Flexible packaging not only has the effects 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, flexible packaging aluminum foil still has a lot of room for development.

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. There are few domestic manufacturers of electrolytic capacitor aluminum foil, mainly because the market demand is not large, and the production technology is far behind the advanced countries. However, aluminum electrolytic capacitors have good performance, low prices, and wide range of uses, so the market prospect is good.
