Introduction to the four application areas of aluminum foil

Edit:admin001 Date: 2019-06-05 10:57
With the rapid development of society, aluminum foil materials have also been used in various industries. Due to its excellent properties, aluminum foil is widely used in food, beverages, cigarettes, pharmaceuticals, photographic bases, household items, etc. The following are the four main applications of aluminum foil materials.
First, automotive composite aluminum foil
There are two kinds of aluminum foil for automobile use. One is composite aluminum foil for automobile air conditioners. China's automobile air conditioners have been fully aluminized, and the annual demand for aluminum foil is 15,000 tons. The other is composite foil for automobile radiators, which is used to manufacture automobiles. Water tank radiators, car condensers and evaporators, the current automotive tank aluminizing rate reached 40%, the annual demand is about 0.3 million tons.
Second, the medicine foil
The pharmaceutical packaging aluminum foil mainly includes a water-based, easy-opening bottle cap for injection and a medicinal PTP aluminum foil. Since the PTP aluminum foil has the advantages of moisture proof, convenient carrying, safety and hygiene, it is widely used in the international pharmaceutical industry. China has been using aluminum foil packaging medicine 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 is developing rapidly, but mainly because 20% aluminum foil is in pharmaceutical packaging. The proportion of applications in the company continues to increase.

Third, flexible packaging aluminum foil
Flexible packaging is a bag-type container made of soft composite aluminum foil packaging material. The appearance of flexible packaging greatly improves the mechanization and automation level of the food and beverage industry, and accelerates the modernization and socialization process of people's eating and drinking life. In the type of packaging bags, aluminum foil can also be made into various types of packaging bags, such as aluminum foil film, aluminum foil vacuum bag packaging bags. In recent years, China's flexible packaging market has also developed rapidly. So far, 10 aluminum foil composite production lines have been introduced, which can be used in different processes such as dry compounding, hot melt compounding and extrusion compounding depending on the use of flexible packaging. Flexible packaging is not only moisture-proof and fresh-keeping, but also can print a variety of patterns and texts. It is an ideal material for modern commercial packaging.
Fourth, aluminum foil for electrolytic capacitors
The aluminum foil used in electrolytic capacitors is a kind of corrosive material working under polar conditions. It has high requirements on the structure of aluminum foil. The aluminum foil used is divided into three types: cathode foil, thickness of 0.015mm~0.06mm; high pressure foil, thickness It is 0.065mm~0.1mm, and it is required to produce aluminum foil with high purity aluminum; low pressure foil with thickness of 0.06mm~0.1mm.
