The so-called double zero foil is a foil with two zeros after the decimal point when its thickness is measured in mm, usually an aluminum foil with a thickness of less than 0.0075mm. When expressed in English, thick foil is called "heavy gaugefoil'", single zero foil is called "medium gaugefoil", and double zero foil is called "lightgaugefoil'". In foreign countries, aluminum foil with thickness ≤40ltm is sometimes called light gauge foil, and aluminum foil with thickness >40btm is collectively called heavy gaugefoil.
According to the different thickness of aluminum plates can be divided into thin plates and medium thick plates. The GB/T3880-2006 standard stipulates that the thickness less than 0.2 mm is called aluminum foil.
Aluminum foil is a hot stamping material that is directly rolled into thin sheets with metal aluminum. Its hot stamping effect is similar to that of pure silver foil, so it is also called fake silver foil. Because aluminum has a soft texture, good ductility, and silver-white luster, if the rolled sheet is mounted on offset paper with sodium silicate and other materials to make aluminum foil, it can also be printed. However, the aluminum foil itself is easy to oxidize and the color becomes dark, and the color will fade when rubbed or touched, so it is not suitable for hot stamping of the covers of books and periodicals that have been stored for a long time. According to the difference in thickness, aluminum foil can be divided into thick foil, single zero foil and double zero foil. The aluminum content of double zero aluminum foil is above 99%.
