The development and types of aluminum for food packaging
Packaging aluminum is one of the uses of aluminum foil. The development of packaging industry is an important symbol of cultural development and scientific and technological progress. Since the 1950s, the rise of composite materials has led to the revolution in the packaging field, which has had some influence on aluminum foil application for packaging. As the aluminum foil has a series of good performance, its wide range of applications, including the largest demand for packaging aluminum.
China's food industry is in an important period of vigorous development, food packaging with aluminum has greatly improved the level of food processing, speed up the modernization of people's food life. In developed countries, food and beverage are mainly used in flexible packaging, while China's flexible packaging development is lagging behind. Aluminum foil in the video packaging applications are mainly two: one is aluminum or aluminum paper composite packaging; the other is aluminum-plastic multi-layer composite packaging. China's demand for aluminum foil is about 30,000 tons / year. From the market trend of development, fresh agricultural products and natural food will be an important development of aluminum packaging market in China.
Used in food packaging aluminum foil has some special requirements, the packaging can be opened after the seal, and to have to heat, fresh, anti-corrosion and moisture-proof characteristics. In meeting these characteristics, aluminum foil has become the first choice for food packaging materials. In addition, according to foreign statistics can achieve about 70% of the recovery rate of packaging products. Food packaging with aluminum foil raw materials are mainly 1 series, 3 series and 8 series of products, including the model 1060,1100,3003,8011,8021 and so on. According to the needs of the packaged food to choose the hardness of the alloy, that is, alloy state, commonly used in the state H14, H16 and H18 these three.
Mingtai Aluminum in the packaging of aluminum, the equipment using Andritz plate roller and Honeywell thickness gauge, to achieve a good plate at the same time, to ensure the precise control of the export thickness. First-class equipment and top instruments to ensure that the food packaging foil printing and mechanical properties, improve the product performance and temperature performance.
