How Does Aluminium Paper Foil Look Like
Aluminum foil production has a history of one hundred years. In 1890, the German Fürth (Fürth) produced small pieces of aluminum foil by hand hammering in its workshop in Nuremberg. In 1905, Swiss industrialists A. Gautsh and Jaguler used block stack rolling to obtain sheet-shaped aluminum foil with a thickness of 0.05 mm. In 1910, Swiss Nehrer (R.V.Nehrer) and others used the coil rolling method to make aluminum foil, which made the aluminum foil enter the stage of industrial production. At that time, a two-high rolling mill was used, the rolling speed was only 10-20m/min, and the coil weight did not exceed 50kg. Since then, the rolling equipment and process technology have been continuously improved, especially after the Second World War, there have been new developments almost every 10 years
Thickness and width of aluminum foil The thickness range of rolled aluminum foil is 0.004:～0.20mm, but different countries have different regulations
The varieties of aluminum foil include roll foil and sheet foil, which are divided into hard foil and soft foil. The aluminum foil directly rolled by the rolling mill is called plain aluminum foil, and the plain aluminum foil processed by different deep processing is called embossed aluminum foil material, composite aluminum foil material, coated aluminum foil material, color aluminum foil and printed aluminum foil material (see coated aluminum foil). From the purity And alloy varieties: industrial pure aluminum foil (purity 99.7%-98.8%), iron-containing pure aluminum foil (containing Fe about 1%), high-purity aluminum foil (purity 99.85%-99.99%) and aluminum alloy foil (aluminum manganese) alloy Foil, aluminum-magnesium alloy foil and hard aluminum foil, etc.). From the use, it can also be classified and named, such as packaging aluminum foil, capacitor aluminum foil and so on.
The mechanical and physical and chemical properties of aluminum foil take into account the use and deep processing requirements of aluminum foil, and the requirements for tensile strength, rupture strength, tear strength and elongation of aluminum foil are put forward. They are related to the purity, thickness, heat treatment state and the used blank of the aluminum foil. And other factors. The reflectance of aluminum foil is 60%-95%. The thinner the aluminum foil, the more rolling passes and the higher the reflectivity. When aluminum foil is used for packaging food, medicines and other items, the moisture permeability and corrosion resistance should be assessed. The unit of moisture permeability is g/(m2•d). The smaller the value, the better.
