Aluminum for packaging is one of the uses of aluminum foil. The development of the packaging industry is an important symbol of cultural development and technological progress. Since the 1950s, the rise of composite materials has triggered a revolution in the packaging field, which has had a certain impact on the application of aluminum foil for packaging. Because aluminum foil has a series of good properties, its application range is very wide, among which the demand for packaging aluminum is relatively large.

China's food industry is in an important period of vigorous development. The emergence of aluminum for food packaging has greatly improved the level of food processing and accelerated the modernization of people's dietary life. In developed countries, food and beverages mainly use flexible packaging, while the development of flexible packaging in China is relatively lagging. There are two main applications of aluminum foil in video packaging: one is aluminum-plastic or aluminum-paper composite packaging; the other is aluminum-plastic-paper multilayer composite packaging. The demand for food aluminum foil in China is about 30,000 tons per year. From the perspective of market development trends, fresh agricultural products and natural foods will become important development markets for packaging aluminum in China.

The aluminum foil used in food packaging has some special requirements. The package can be resealed after it is opened, and it must have the characteristics of heating, preservation, anticorrosion and moisture resistance. In meeting these characteristics, aluminum foil has become the preferred food packaging material. In addition, according to foreign statistics, a recycling rate of about 70% of packaging products can be achieved. The raw materials of aluminum foil for food packaging are mainly 1 series, 3 series and 8 series products, mainly including models 1060, 1100, 3003, 8011, 8021, etc. According to the requirements of the food to be packaged, select the degree of hardness of the alloy, that is, the alloy state. The commonly used states are H14, H16 and H18.
