Generally speaking, according to the different thickness of aluminum foil, 8011 aluminum foil can be divided into: thick foil, single zero foil and double zero aluminum foil.
② Single Zero Foil: foil having a thickness of 0.01 mm and less than 0.1 mm.
③Double Zero Foil: the so-called double-foil is in its thickness in mm units of measurement when the decimal point after the two zero foil, usually less than 0.01 thickness of aluminum foil, 0.005 ~ 0.009mm aluminum foil. In English, the thick foil is called heavy gauge foil, the single piece of foil is called medium gauge foil and the double foil is called light gauge foil. Foreign sometimes the thickness of ≤ 40ltm aluminum foil called light gauge foil, and the thickness of> 40btm aluminum foil collectively referred to as heavy gauge foil.
