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 eating and drinking. In developed countries, food and beverages mainly use flexible packaging, while the development of flexible packaging in China is relatively lagging behind. 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 multi-layer composite packaging. The demand for Chinese food aluminum foil is about 30,000 tons/year. From the perspective of market development trends, fresh agricultural products and natural foods will become important development markets for aluminum for packaging in China.
There are some special requirements for the application of aluminum foil for food packaging. The package can be resealed after opening and has the characteristics of being heatable, fresh, anti-corrosive and moisture-proof. In meeting these characteristics, aluminum foil has become the first choice for food packaging materials. In addition, about 70% of the packaging product recovery rate can be achieved according to foreign statistics. The raw materials for aluminum foil for food packaging are mainly 1 series, 3 series and 8 series products, mainly including models 1060, 1100, 3003, 8011, 8021 and the like. The degree of hardness of the alloy, that is, the state of the alloy, is selected according to the requirements of the packaged food. The commonly used states are H14, H16 and H18.
In the aluminum for packaging, Mingtai Aluminum uses ANDRITZ plate rolls and Honeywell thickness gauges to achieve a good plate shape while ensuring precise control of the exit thickness. First-class equipment and top-level instruments ensure the printing and mechanical properties of food packaging foils, improving product insulation and temperature resistance.
