Aluminum foil is widely used in food, beverage, cigarettes, pharmaceuticals, photographic backplanes, household articles, etc., and is usually used as a packaging material; electrolytic capacitor materials; insulation materials for buildings, vehicles, ships, houses and the like; As decorative gold and silver lines, wallpaper, and various types of stationery printed matter and light industrial products and decorating trademarks. Among the above-mentioned various applications, the most effective performance of aluminum foil is the point of packaging material. Aluminum foil is a soft metal film, not only has moisture, airtight, shading, wear resistance, fragrance, non-toxic tasteless advantages, but also because of its elegant silver-white gloss, easy to process a variety of beautiful colors and patterns Pattern, and thus more vulnerable to people's

Favor. In particular, the combination of aluminum foil with plastic and paper combines the shielding properties of aluminum foil with the strength of the paper and the heat-sealing property of the plastic to further improve the shielding properties for water vapor, air, ultraviolet rays, bacteria and the like as a packaging material , Greatly expanding the application of aluminum foil market. As the packaging of goods and the outside light, wet, gas and other fully isolated, so that the packaging has been well protected. Especially for cooking food packaging, the use of such composite aluminum foil material, at least to ensure that food is not bad for more than a year. Moreover, the heating and unpacking are very convenient, by the consumers.

With the improvement of people's living standards and the development of tourism, beer, soft drinks and other beverages and canned food demand increasing, these need to have modern packaging and decoration, in order to facilitate competition in the international market. In order to meet the market requirements, people have developed a good shielding plastic film and sprayed foil and other packaging materials, but their overall performance than coating and laminating processing can be made up and improved. It can be said that aluminum foil is a variety of excellent performance, more perfect packaging materials, in many areas are fully demonstrated its broad application prospects.

In order to improve the rolling efficiency and the quality of aluminum foil products, modern aluminum foil rolling mill to the volume, wide, high-speed, automated four directions. Contemporary aluminum foil rolling mill roll width has reached more than 2200mm, rolling speed of 2000m / min or more, weighing more than 20t. The corresponding automation level of the rolling mill is also greatly improved. Thickness control system (AGC) is generally installed, most of which are installed with AFC. Aluminum foil industry is facing a period of rapid development.
