Aluminum foil has a wide range of uses. It is used in various industries such as food packaging, medicines, vehicles, air conditioners, capacitors, lithium batteries, cables, etc. Shanghai Lumeng Aluminum Co., Ltd. provides aluminum foils of various thicknesses and materials. Welcome to consult .

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 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 the 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.

2. medicated foil
Pharmaceutical packaging aluminum foil mainly includes easy-open bottle caps for liquids, injections, and pharmaceutical PTP aluminum foil. Because PTP aluminum foil has the advantages of moisture-proof, convenient carrying, safety and health, it is widely used in the international pharmaceutical industry. my country 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 pharmaceutical market has developed rapidly, but it is mainly because 20% of aluminum foil is used in pharmaceutical packaging. The proportion of applications in China continues to increase.

2. composite foil for automobiles
With the vigorous development of my country's automobile industry and the continuous increase of automobile aluminumization rate, the market demand for automobile foils is increasing 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 automobile radiators, which is used to manufacture automobile water tank radiators, automobile condensers and evaporators. The current automobile water tank aluminumization rate reaches 40%, and the annual demand The amount is about 3 million tons.

4. aluminum foil for electrolytic capacitors
The aluminum foil used in electrolytic capacitors is a corrosive material that works under polar conditions. It has higher 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 to 0.06mm; high-voltage foil, with a 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-pressure foil is 0.06mm~0.1mm.

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 price, and a wide range of uses, so the market prospect is good. The current annual demand in Japan 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.
