Flexible packaging is a bag-type container made of soft composite packaging materials. The appearance 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 eating and drinking life. In developed countries, flexible packaging has become one of the main packaging forms for food and beverages, replacing canned and bottled products within a certain range.

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.

With the improvement of people's living standards, there is still a lot of room for development of flexible packaging aluminum 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. With the vigorous development of China's automobile industry and the continuous improvement of automobile aluminizing rate, the market demand for automotive foils has increased rapidly. There are two kinds of foils for automobiles, one is composite foil for automobile air conditioners, and China's automobile air conditioners have been fully Aluminized, the annual demand for aluminum foil reaches 15,000 tons; the other is composite foil for automotive radiators, used in the manufacture of automotive water tank radiators, car condensers and evaporators. At present, the aluminum tank rate of automotive water tanks reaches 40%, annual demand The amount is about 0.3 million tons.
