The thickness of the aluminum foil
Variations may be divided in keeping with the thickness of aluminum foil thick foil, unmarried zero foil and double zero foil.
① foil thickness: zero.1 ~ zero.2mm thickness of the foil.
② unmarried 0 foil: the thickness of 0.01mm and less than 0.1mm / foil.(aluminum foil roll)
③ double 0 foil: the so-called double-zero when the foil thickness is in mm devices of measurement after the decimal two zero foil, commonly aluminum foil having a thickness of much less than 0.01, i.E., 0.0.5 ~ 0.009mm aluminum foil.
Aluminum foil characteristics
Aluminum foil having a easy, hygienic and vibrant look, it could be used with many other packaging substances manufactured from integrated packaging materials, aluminum foil and floor printing consequences than different substances are exact, further to aluminum foil in addition to the subsequent functions:
