Introduction and Uses of Aluminum Foil

Ⅰ. Definition of aluminum foil

Aluminum foil is a kind of hot stamping material made of metal aluminum directly calendered into thin sheets. It has soft texture, good elasticity and silvery-white lustre, it also has the advantages of moisture-proof, air-tight, shading, abrasion resistance, non-toxic and tasteless, etc. Aluminum foil uses in food, beverage, cigarette, medicine, photographic plate, household necessities, construction, vehicles and other industries.


Ⅱ. The aluminum foil uses

1. Auto industry


With the booming development of China's automobile industry and the continuous improvement of the aluminized rate of automobiles, the market demand for aluminium foil for automobiles has increased rapidly. The compound foil for automobile air conditioner is used to manufacture radiators of automobile water tanks, car condensers and evaporators. The current aluminized rate of car water tank reaches 40%, and the annual demand is about 0.3 million tons. The compound foil for car radiator is used to manufacture radiators of automobile water tank, car condenser and evaporator, the current aluminized rate of car water tank is 40%, and the annual demand is about 0.3 million tons.


2. Medicine


Aluminum foil for medicine packaging mainly includes easy to open bottle caps of liquid medicine, injection medicine and pharmaceutical PTP aluminum foil. PTP aluminum foil is widely used in the international pharmaceutical industry because of its advantages of being moisture-proof, easy to carry, safe and healthy, etc. In the last few years, the pharmaceutical foil market has developed rapidly, on the one hand, the pharmaceutical market has quickly developed, however, mainly because the application proportion of 20% aluminium foil in medicine packaging is increasing continually.


3. Flexible package


Flexible packaging is a bag container made of soft composite packaging materials. The emergence of flexible packaging has greatly improved the mechanization and automation level of food and beverage industry, it also accelerated the modernization and socialization process of people's diet culture. Commercial aluminum foil flexible packaging has become one of the main packaging forms of food and beverage, replacing cans and bottles in a certain range. Flexible packaging not only has the effects of moisture-proof and preservation, but it also can print all kinds of patterns and words. It is the ideal material for modern commercial packaging. With improving people's living standards, flexible packaging aluminum foil still has a great development space.


4. Electrolytic condenser


Commercial aluminum foil used for electrolytic condensers is a kind of corroded material working under polar conditions, which has higher requirements on the structure of aluminum foil. Aluminum electrolytic condensers have good properties, the price is inexpensive, and it has been widely used. With the development of the electronic industry and China becoming a major industrial production base, the aluminum foil market demand for electrolytic condensers is promising.
