Aluminium foil is a kind of hot stamping material that is directly rolled into a thin sheet with aluminum. Its hot stamping effect is similar to that of pure silver foil, so it is also called a false silver foil. Because of its soft texture, good ductility, and silvery-white luster, aluminum foil can also be printed if the calendered sheet is mounted on offset paper with sodium silicate and other substances. However, aluminum foil itself is easy to oxidize and darken and will fade when rubbing and touching, so it is not suitable for the long-term preservation of books and periodicals cover.
Everything You Need To Know About Aluminium Foil
Because of its excellent characteristics, aluminium foil supplier is widely used in food, beverage, cigarette, medicine, photographic base plate, household goods, etc., and is usually used as its packaging material; electrolytic capacitor material; thermal insulation material for buildings, vehicles, ships, houses, etc.; it can also be used as decorative gold and silver thread, wallpaper, and decoration trademark for various stationery printing products and light industrial products. Among all the above applications, the most effective one is as packaging material.
Aluminum foil is a soft metal film, which not only has the advantages of moisture-proof, airtightness, shading, abrasion resistance, fragrance preservation, non-toxic and tasteless, but also has elegant silver-white luster, and is easy to process beautiful patterns and patterns of various colors, so it is more easily favored by people. In particular, after aluminium foil is compounded 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, which is necessary for packaging materials, and greatly expands the application market of aluminum foil.
Because the packaged goods are completely isolated from the outside light, humidity, and gas, the packaged goods are well protected. Especially for the packaging of cooked food, the use of this composite aluminum foil material can ensure that the food will not deteriorate for at least one year. Moreover, heating and unpacking are very convenient, which is very popular with consumers.
With the improvement of living standards and the development of tourism, the demand for beer, soda and other drinks and canned food is increasing day by day. All these need modern packaging and decoration in order to facilitate the competition in the international market. In order to meet the requirements of the market, packaging materials such as plastic film and spray foil with good shielding properties have been developed. However, their comprehensive properties are not as good as those of over-coating and laminating. 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, the modern aluminum foil rolling mill develops in four directions: large coil, wide width, high speed, and automation. The roll width of the modern aluminum foil rolling mill has reached more than 2200mm, the rolling speed has reached more than 2000m / min, and the coil weight has reached more than 20t. The automation level of the rolling mill has been greatly improved. AGC and AFC are widely installed. Aluminum foil industry is facing a period of rapid development.
