Four major aluminum foil application fields
Aluminum foil is a hot stamping material that is directly calendered into thin sheets with metal aluminum. Its hot stamping effect is similar to that of pure silver foil. Therefore, it is also called fake silver foil. Due to its excellent characteristics, aluminum foil is widely used in food and beverages. , Cigarettes, medicines, photographic substrates, household daily necessities, etc., are usually used as their packaging materials. Let's take a look at the four major aluminum foil applications.
1. Composite for automobile
With the vigorous development of my country's automobile industry and the continuous improvement of automobile aluminumization rate, 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. Aluminization, the annual demand for aluminum foil reaches 15,000 tons; the other is composite foil for automotive radiators, which is used to manufacture automotive water tank radiators, automotive condensers and evaporators. The current automotive water tank aluminization rate reaches 40%, and the annual demand The amount is about 3 million tons.
Two, medicated foil
Pharmaceutical packaging aluminum foil mainly includes easy-open bottle caps for liquids and injections and medicinal PTP aluminum foil. Because PTP aluminum foil has the advantages of moisture resistance, convenient carrying, and hygiene, it is widely used in the international pharmaceutical industry. my country has been using aluminum foil packaging since 1985 Pharmaceuticals, 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 the proportion of 20% aluminum foil in pharmaceutical packaging continues to increase.
3. Aluminum foil and flexible packaging aluminum foil for cable materials
The aluminum foil for wire and cable is made of aluminum-plastic composite, and the flexible packaging aluminum foil is a bag 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 of people's dietary life. Socialization process. In developed, flexible packaging has become one of the main packaging forms for food and beverages, replacing canned and bottled in a certain range. In recent years, China's flexible packaging market has also developed rapidly, and 10 The aluminum foil composite production line can adopt different processes such as dry composite, hot melt composite, and extrusion composite according to the different uses of aluminum foil. Flexible packaging not only has the effects of moisture-proof and fresh-keeping, but also can print various patterns and texts, which is the modern commercial packaging Ideal material. With the improvement of people's living standards, flexible packaging aluminum foil still has a lot of room for development.
Fourth, aluminum foil for electrolytic capacitors
The aluminum foil used in electrolytic capacitors is a corrosive material that works under polar conditions. It has high requirements for the structure of the aluminum foil. The aluminum foil used is divided into three types: cathode foil, with a thickness of 0.015mm~0.06mm; high-voltage foil, thickness It is 0.065mm~0.1mm, and the aluminum foil is required to be produced with high-purity aluminum; the low-pressure foil has a thickness of 0.06mm~0.1mm.
There are few manufacturers of aluminum foil for electrolytic capacitors in China, mainly because the market demand is not large, and the production technology is far behind. However, aluminum electrolytic capacitors have good performance, low prices, and a wide range of uses, so the market prospects are very good. The current year in Japan The demand is 45,000 tons, which is 6 times that of the Chinese market. With the development of the electronics industry and China becoming a major industrial production base, the market demand for electrolytic capacitor aluminum foil is promising.
