First, 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 of the food and beverage industry, and accelerated the modernization and socialization of people’s diet. In developed countries, flexible packaging has become one of the main packaging forms for food and beverages, replacing canned and bottled to a certain extent. In recent years, China’s flexible packaging market has also developed rapidly. So far, 10 aluminum foil composite production lines have been introduced. 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 moisture-proof and fresh-keeping effects, but also can print a variety of patterns and text, is an ideal material for modern commercial packaging. With the improvement of people’s living standards, there is still much room for development of flexible packaging aluminum foil.
Second, medicine foil
Medical packaging aluminum foil mainly includes water-based, injection-type easy-open bottle caps and medicinal PTP aluminum foil. Because PTP aluminum foil has the advantages of moisture resistance, easy carrying, safety and health, it is widely used in the international pharmaceutical industry. China has been using aluminum foil to package medicines since 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 pharmaceutical market has developed rapidly, but mainly because 20% aluminum foil is used in pharmaceutical packaging. The proportion of applications in it is constantly increasing.
Third, automotive composite foil
With the booming development of China’s auto industry and the continuous increase of the aluminization rate of automobiles, the market demand for automotive foils has rapidly increased. There are two types of automotive foils. One is the composite foil for automotive air conditioners. Aluminization, the annual demand for aluminum foil reaches 15,000 tons; the other is a composite foil for automobile radiators, which is used to manufacture automobile water tank radiators, automobile condensers and evaporators. At present, the aluminization rate of automotive water tanks reaches 40%, and the annual demand is The amount is about 0.3 million tons.
Fourth, aluminum foil for electrolytic capacitors
The aluminum foil used in electrolytic capacitors is an corrosive material that works under polar conditions. It has high requirements on the structure of the aluminum foil. There are three types of aluminum foils used: cathode foils with a thickness of 0.015mm to 0.06mm; high-voltage foils with a thickness of It is 0.065mm ~ 0.1mm, and requires aluminum foil to be produced from high-purity aluminum; low-pressure foil, thickness is 0.06mm ~ 0.1mm.
