Application of aluminum foil

Because of its excellent characteristics, aluminum foil is widely used in food, beverage, cigarette, medicine, photographic plate, household commodities, etc., usually used as its packaging materials; Electrolytic capacitor material; Insulation materials for buildings, vehicles, ships, houses, etc.; It can also be used as decorative gold and silver thread, wallpaper and decoration trademarks of various stationery prints and light industrial products. Among these applications, the most effective use of aluminum foil is as a packaging material. Aluminum foil is a soft metal film, not only has the advantages of moisture-proof, air-tight, light shading, abrasion resistance, fragrance protection, non-toxic and tasteless, but also because of its elegant silver luster, easy to process a variety of colors of beautiful patterns and patterns, so it is easier to be favored by people. Especially after aluminum foil is combined with plastic and paper, the shielding property of aluminum foil is integrated with the strength of paper and the thermal sealing property of plastic, which further improves the shielding property of water vapor, air, ultraviolet and bacteria necessary for packaging materials and greatly broadens the application market of aluminum foil. Due to the packaging of the goods and the outside light, humidity, gas, etc. fully isolated, so that the packaging is intact protection. Especially for the packaging of cooking food, the use of this composite aluminum foil material, at least can ensure that the food does not deteriorate for more than a year. Moreover, it is convenient to heat and open the bag, which is very popular among consumers.

With the improvement of people's living standard and the development of tourism, the demand of beer, soda and other drinks and canned food is increasing day by day, which need to have modern packaging and decoration, in order to facilitate the competition in the international market. In order to meet the requirements of the market, people have developed good shielding plastic film and spray foil packaging materials, but their comprehensive properties can not be as good as over coating and lamination processing can be made up and improved. Therefore, it can be said that aluminum foil is a perfect packaging material with a variety of excellent properties, which fully shows its broad application prospects in many fields.
In order to improve the rolling efficiency and the quality of aluminum foil products, modern aluminum foil rolling mill is developing to four directions: large roll, wide width, high speed and automation. The width of the roll body of contemporary aluminum foil mill has reached more than 2200mm, the rolling speed has reached more than 2000m/min, and the rolling weight has reached more than 20t. The corresponding level of mill automation has also been greatly improved, and thickness control systems (AGCs) are commonly installed, most of which are plate shape meters (AFCs). Aluminum foil industry is facing a period of rapid development.
