Development And Types Of Aluminum For Food Packaging
- Nov 26, 2018 -

Aluminum for packaging is one of the uses of aluminium 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 triggered a revolution in packaging field, which has a certain impact on the application of aluminum foil for packaging. Aluminum foil has a series of good properties, and its application is very wide. Among them, the demand for aluminum for packaging is the largest.

China's food industry is in an important period of vigorous development. The appearance of aluminium for food packaging has greatly improved the level of food processing and accelerated the modernization of people's dietary life. In developed countries, soft packaging is mainly used for food and beverage, while the development of soft packaging in China lags behind. There are two main applications of aluminium foil in video packaging: one is aluminium-plastic or aluminium-paper composite packaging; the other is multi-layer composite packaging of aluminium-plastic paper. The demand for food aluminum foil in China is about 30,000 tons per year. From the perspective of market development trend, fresh agricultural products and natural food will become an important development market of aluminum for packaging in China.

There are some special requirements for aluminium foil used in food packaging. The packaging can be re-sealed after opening, and it should have the characteristics of heating, fresh-keeping, anti-corrosion and moisture-proof. In order to meet these characteristics, aluminum foil has become the first choice of food packaging materials. In addition, according to foreign statistics, about 70% of the recovery rate of packaging products can be achieved. The raw materials of aluminum foil for food packaging are mainly products of series 1, 3 and 8, mainly including models 106, 1100, 3003, 8011, 8021, etc. The degree of hardness and softness of the alloy, i. e. alloy state, is selected according to the requirements of the packaged food. The commonly used states are H14, H16 and H18.
