Introduction of aluminum foil

Date: 2019-06-10 14:01
 A hot stamping material which is directly calendered into a sheet by metal aluminum, and its hot stamping effect is similar to that of pure silver foil stamping, so it is also called a fake silver foil. Since aluminum has a soft texture and good ductility, it has a silvery white luster. If the calendered sheet is smashed on an offset paper with a material such as sodium silicate, an aluminum foil sheet can be formed. However, the aluminum foil itself is easily oxidized and the color is darkened, and friction, touch, and the like are discolored, and thus it is not suitable for hot stamping of a book cover that has been preserved for a long time.
 
Aluminum coil
   Due to its excellent properties, aluminum foil is widely used in food, beverages, cigarettes, pharmaceuticals, photographic bases, household daily necessities, etc., and is usually used as its packaging material; electrolytic capacitor materials; thermal insulation materials for buildings, vehicles, ships, houses, etc.; As a decorative gold and silver wire, wallpaper and various types of stationery printed matter and light industrial products, decorative trademarks. Among the above various applications, the most effective performance of the aluminum foil is as a packaging material. Aluminum foil is a soft metal film, which not only has the advantages of moisture-proof, air-tight, light-shielding, abrasion resistance, fragrance preservation, non-toxic and tasteless, but also because it has an elegant silver-white luster, it is easy to process beautiful patterns of various colors and The pattern is thus 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 improving the shielding performance for water vapor, air, ultraviolet rays and bacteria which are necessary as packaging materials. , greatly expanded the application market of 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 composite aluminum foil material 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 packaging material with various excellent properties and perfect, and it has fully demonstrated its broad application prospect in many fields.
