What is the Aluminium

Aluminum is a very active metal. It is prone to oxidation when exposed to natural environment for a long time. Therefore, aluminum foil should be protected from moisture. The finished double-zero aluminum foil is very soft and is prone to plastic deformation. The slight collision or scratching and pressing will deform the aluminum foil, and the performance will be degraded. Serious collision or scratching or pressing may cause the aluminum foil to be scrapped. Therefore, the aluminum foil should be suspended or placed in softness. On the surface of the water platform, the aluminum foil box can not be tilted or inverted, and the aluminum foil roll can only be lifted horizontally and cannot be tilted or moved vertically. Aluminum foil should be protected against deformation of the core during transportation and use.
Aluminum is the most abundant metal in the earth's crust. It was discovered in the early eighteenth century and is one of the most widely used metals in non-ferrous metals. The aluminum foil produced by remelting aluminum ingot after molten aluminum or liquid electrolytic aluminum is processed by composition adjustment, refining, casting hot rolling or casting, cold rolling, annealing, foil rolling, slitting and finish annealing, etc., has the following characteristics: :
Small specific gravity, larger than surface, low cost of use; high electrical conductivity; good thermal conductivity of contact, strong radiation and heat insulation;
Good air tightness; high strength ratio; more corrosion resistant in daily environment; good cold deformation performance;
The aluminum foil produced by aluminum not only has the advantages of moisture-proof, air-tight, light-shielding, abrasion-resistant, fragrant, non-toxic and tasteless, but also because of its elegant silver-white luster, it is easy to process beautiful patterns and patterns of various colors. Therefore, it is more likely to be favored by 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.
