Because of its excellent characteristics, aluminum foil is widely used in food, beverage, cigarettes, pharmaceuticals, photographic substrates, household articles, etc. It is usually used as packaging materials; electrolytic capacitor materials; insulation materials for buildings, vehicles, ships, houses, etc. It can also be used as decorative gold and silver wire, wallpaper and decorative trademarks of various stationery, printing products and light industrial products. In all the above applications, the most effective way to develop the performance of aluminium foil is as packaging material. Aluminum foil is a soft metal film, which not only has the advantages of moisture-proof, air-tight, shading, wear-resistant, fragrance-preserving, non-toxic and tasteless, but also because of its elegant silver-white luster, easy to process beautiful patterns and patterns of various colors, so it is more likely to be favored by people’s aluminum foil tape.
With the improvement of people’s living standards and the development of tourism, the demand for beer, soda and other beverages and canned food is increasing day by day, which requires modern packaging and decoration to facilitate competition in the international market. In order to meet the market requirements, people have developed good shielding plastic film and spray foil packaging materials, but their comprehensive properties are not as good as coating and lamination processing can be made up and improved.
After aluminum foil deflector beanie is compounded with plastics and paper, the shielding property of aluminium foil is integrated with the strength of paper and the thermal sealing property of plastics, which further improves the shielding properties of water vapor, air, ultraviolet ray and bacteria, which are necessary for packaging materials, and greatly expands the application market of aluminium foil. Aluminum foil manufacturer is well protected because of its full isolation from light, humidity and air outside. Especially for the packaging of cooked food, the use of this composite aluminum foil material can ensure that food does not deteriorate for at least one year. Moreover, heating and unpacking are very convenient and popular with consumers.
Therefore, it can be said that aluminium foil is a kind of perfect packaging material with many excellent properties, which fully shows its broad application prospects in many fields. In order to improve rolling efficiency and quality of heavy duty aluminum foil products, modern aluminium foil rolling mills are developing in four directions: large coil, wide width, high speed and automation. The roll width of contemporary aluminium foil mill has reached more than 2200 mm, the rolling speed has reached more than 2000 m/min, and the coil weight has reached more than 20 t. The automation level of the rolling mill is also greatly improved. AGC is generally installed, and AFC is mostly installed. Aluminum foil industry is facing a period of rapid development.
