Development And Types Of Aluminum For Food Packaging

- Dec 29, 2018-

Aluminium for packaging 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, and since the 50 's, the rise of composite materials has triggered a revolution in the field of packaging, 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 greater. 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, speeding up the modernization of people's food and life. In developed countries, food and beverages mainly use soft packaging, and China's flexible packaging development 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.

Judging from the trend of market development, fresh agricultural products and natural food will become an important development market for Chinese packaging aluminum. Used in food packaging aluminum foil has some special requirements, packaging can be re-sealed after opening, and to have heating, preservation, anti-corrosion and moisture-proof characteristics. In meeting the requirements of these characteristics, aluminum foil has become the optimization of food packaging materials. In addition, according to foreign statistics can also achieve about 70% of the recovery rate of packaging products. The raw materials for aluminum foil for food packaging are mainly 1 series, 3 Series and 8 series products, mainly including models of 1060, 1100, 3003, 8011, 8021 and so on.

According to the demand of the packaged food to choose the degree of soft and hard alloy, that is, the state of the alloy, commonly used in the state of H14, H16 and H18 these three kinds. In terms of aluminum for packaging, the equipment uses Andritz plate rollers and Honeywell thickness gauges to achieve good plate type while ensuring precise control of outlet thickness. First-class equipment and high-quality instruments to ensure the printing effect and mechanical properties of food packaging foil, improve the product air separation performance and temperature resistance performance.
