Aluminum Foil Application

Aluminum foil is nothing more than a sheet of aluminum alloy with a thickness between 0.004 and 0.24 mm. Aluminum foil is 8 times thinner than banknotes, yet it provides perfect protection against light, liquids and germs. Because of these properties, many groceries packaged in materials including aluminum foil typically have a shelf life of more than 12 months.

Aluminium foil is widely used in industrial markets due to its versatility. They can be used to manufacture various products in different fields. Aluminum is very common because of its properties: light weight, durability, electrical and thermal conductivity, machinability, aesthetics, corrosion resistance. Furthermore, this material can be recycled infinitely without losing its properties.

Aluminium foil is made on a rolling mill, a process that involves pulling a sheet of aluminium under pressure between two rotating rolls. The resulting ultra-thin sheet or foil is then cut into rolls using a special cutter. The most common materials used in foil production are pure primary aluminium or 1xxx, 3xxx and 8xxxx series alloys, including iron, silicon, manganese and occasionally copper if higher strength is required. The heated aluminium is rolled into sheets (hot rolled) 2 to 100 mm thick. They are then cold rolled into foil of the desired thickness.

The aluminum foil thickness is less than 0.20mm, and the cross section is rectangular and uniform. Including capacitor aluminum foil, hydrophilic aluminum foil, composite aluminum foil, etc. Because of its excellent characteristics, it is widely used in food, beverages, cigarettes, medicines, photographic plates, household daily necessities, etc., and is usually used as its packaging materials; electrolytic capacitor materials; thermal insulation materials for buildings, vehicles, ships, houses, etc.; Decorative gold and silver threads, wallpapers, and all kinds of stationery prints and decoration trademarks of light industrial products, etc. Among the above-mentioned various uses, the one that can exert the most effective performance point of aluminum foil is as a packaging material. Aluminum foil is a soft metal film, which not only has the advantages of moisture resistance, air tightness, shading, abrasion resistance, fragrance preservation, non-toxic and tasteless, etc., but also because of its elegant silver-white luster, it is easy to process beautiful patterns and patterns of various colors. pattern, so it is more likely to be favored by people.
