Thickness

Aluminum foil According to the thickness difference can be divided into thick foil, single 0 foil and double 0 foil.

① Thick Foil ("heavy gaugefoil"): foil with a thickness of 0.1~0.2mm.

② Single 0 Foil ("medium gauge foil"): foil with a thickness of 0.01mm and less than 0.1mm/. ③ Double 0 Foil ("light gauge Foil"): the so-called double 0 foil is in its thickness to mm as the unit of measurement when the decimal point has two zeros of foil, usually less than 0.01 thickness of aluminum foil, that is, 0.005~0.009mm aluminum foil.

Abroad sometimes refers to the thickness of ≤40LTM aluminum foil called "light gauge foil", and the thickness of >40BTM aluminum foil collectively referred to as "heavy gauge foil."

Shape Aluminum foil According to the shape can be divided into curly aluminum foil and flake aluminum foil.

Aluminum foil deep processing wool most of the roll supply, only a few handicraft packaging occasions with flake aluminum foil.

According to the state can be divided into hard foil, semi-hard foil and soft foil.

① Hard foil: After rolling without softening treatment (annealing) of aluminum foil, without skimming treatment, the surface of the residual shantou.

Therefore, hard foil must be skimmed before printing, bonding, coating, if used for forming processing can be used directly.

② Semi-hard foil: aluminum foil hardness (or strength) of aluminum foil between hard foil and soft foil, usually used for forming processes.

③ Soft foil: After rolling after full annealing and softening of aluminum foil, soft material, no residual oil on the surface. Most applications, such as packaging, compounding, electrical materials, etc., use soft foil.
