What Are The Uses Of Aluminum Foil?
- Nov 20, 2018 -

One. Soft packaging aluminum foil

Soft packaging is a bag container made of soft composite packaging materials. The emergence of soft packaging has greatly improved the mechanization and automation level of food and beverage industry, and accelerated the modernization and socialization process of people's dietary life. In developed countries, soft packaging has become one of the main packaging forms of food and beverage, replacing canned and bottled in a certain range. In recent years, China's soft packaging market has also developed rapidly. So far, 10 aluminum foil composite production lines have been introduced. Dry composite, hot melt composite and extrusion composite processes can be adopted according to the different uses of soft packaging. Soft packaging not only has the function of moisture-proof and fresh-keeping, but also can print various patterns and words. It is an ideal material for modern commercial packaging. With the improvement of people's living standards, soft packaging aluminum foil still has great room for development.

Two. Drug foil

Medical packaging aluminium foil mainly includes water agent, injection easy-to-open bottle cap and medicinal PTP aluminium foil. Because PTP aluminium foil has the advantages of moisture-proof, easy to carry, safety and health, it is widely used in the international pharmaceutical industry. Aluminum foil has been used in pharmaceutical packaging since 1985. So far, only 20% of pharmaceutical packaging materials are packaged with aluminium foil. In recent years, the pharmaceutical foil market has developed rapidly. On the one hand, the pharmaceutical market has developed rapidly, but mainly because the application proportion of 20% aluminium foil in pharmaceutical packaging has been increasing.

Three, automobile composite foil

With the vigorous development of China's automotive industry and the continuous improvement of automotive Aluminization rate, the market demand for automotive foil increases rapidly. There are two kinds of automotive foil, one is composite foil for automotive air conditioner. China's automotive air conditioner has been fully aluminized, and the annual demand for aluminium foil reaches 15,000 tons; the other is composite foil for Automotive radiator. Foil is used to manufacture radiator, condenser and evaporator of automobile water tank. At present, the Aluminization rate of automobile water tank reaches 40%, and the annual demand is about 0.3 million tons.

Four. Aluminum foil for electrolytic capacitors

Aluminum foil used in electrolytic capacitor is a kind of corrosive material working under polar conditions, which has higher requirements for the structure of aluminum foil. The aluminum foil used is divided into three kinds: cathode foil, thickness is 0.015mm-0.06mm; high voltage foil, thickness is 0.065mm-0.1mm, requiring the production of high purity aluminum foil; low voltage foil, thickness is 0.06mm-0.1mm.

Domestic electrolytic capacitor aluminium foil manufacturers are few, the main reason is that the market demand is not big, and there is a big gap between production technology and advanced countries. However, aluminum electrolytic capacitors have good performance, low price and wide use, so the market prospect is very good. At present, Japan's annual demand is 45 thousand tons, which is 6 times that of the Chinese market. With the development of electronics industry and China becoming the main industrial production base, the market demand of electrolytic capacitor aluminium foil has broad prospects.
