Aluminum foil characteristics

Due to its excellent properties, Aluminum foil is widely used in food, beverage, cigarette, pharmaceutical, photographic floor, household and daily necessities, etc., and is usually used as its packaging material; electrolytic capacitor materials; thermal insulation materials for buildings, vehicles, ships, houses, etc.; It can be used as a decorative gold and silver thread, wallpaper, and various decorative labels for stationery and light industrial products. Among the above various applications, the most effective performance of the aluminum foil performance is as a packaging material. Aluminum foil is a soft metal film that not only has moisture, airtightness, shading, abrasion resistance, aroma, non-toxic and tasteless, but also has an elegant silver-white luster, which is easy to process beautiful patterns of various colors. And the pattern, so it is more popular with people. In particular, after the aluminum foil is combined with plastic and paper, the shielding property of the aluminum foil is integrated with the strength of the paper and the heat sealing property of the plastic, thereby further enhancing the shielding of water vapor, air, ultraviolet rays and bacteria necessary as a packaging material. Performance has greatly expanded the application market for Aluminum foil. Since the packaged article is sufficiently isolated from the outside light, moisture, gas, etc., the package is well protected. Especially for the packaging of retort foods, the use of this food foil can at least guarantee that the food does not deteriorate for more than one year. Moreover, heating and unpacking are very convenient and are very popular among consumers.

With the improvement of people’s living standards and the development of tourism, the demand for beverages and canned foods such as beer and soda is increasing. These require modern packaging and decoration to facilitate competition in the international market. In order to meet the market requirements, packaging materials such as plastic film and spray foil have been developed, but their overall performance is not as good as that of overcoating and lamination. Therefore, it can be said that Aluminum foil is a perfect packaging material with a variety of excellent properties, and it has fully demonstrated its broad application prospects in many fields.

In order to improve rolling efficiency and quality of Aluminum foil products, modern aluminum foil rolling mills are developing in four directions: large volume, wide width, high speed and automation. The width of the roll of the contemporary aluminum foil rolling mill has reached 2200mm or more, the rolling speed has reached 2000m/min or more, and the coil weight has reached 20t or more. The corresponding level of rolling mill automation has also been greatly improved, the thickness control system (AGC) is generally installed, and most of them are equipped with a shape meter (AFC). The aluminum foil industry is facing a period of rapid development.
