At present, the food packaging requirements have been increasing. For some high-temperature food packaging, aluminum foil packaging bags must be used. The aluminum foil packaging foods have the advantages of good sealing, moisture proof, odorless, good vacuuming effect, low air permeability, and aging resistance. Characteristics; aluminum foil bags in the packaging of electronic components, hardware, industrial products have moisture, rust, anti-static, shielding, shading and other characteristics; then the current aluminum foil packaging bags are used in which field? The following is a detailed introduction with the majority of users:
First, flexible
food packaging aluminum foil bag
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.
Second,
pharmaceutical aluminum foil packaging
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.

The aluminum foil package used for unwinding capacitor is a kind of corrosive material working under polar conditions. It has high requirements on the structure of aluminum foil bag. The aluminum foil bag used is divided into three types: cathode aluminum foil, thickness of 0.015mm~0.06mm; high pressure Aluminum foil, thickness 0.065mm ~ 0.1mm, requires aluminum foil to be produced with high purity aluminum; low pressure aluminum foil, thickness 0.06mm ~ 0.1mm.
There are fewer manufacturers of domestic electrolytic capacitor aluminum foil, mainly because the market demand is not large, and the production technology has a large gap with advanced countries. However, aluminum electrolytic capacitors have good performance, low price and large use, so the market prospect is very good. At present, Japan's annual demand is 45,000 tons, which is six 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 packaging bags is broad.
