The aluminum foil can be divided into a rolled aluminum foil and a sheet aluminum foil according to the shape. Most of the aluminum foil deep-processing wool is supplied in rolls, and only a few hand-made industrial packaging uses sheet-like aluminum foil.
Aluminum foil can be classified into hard foil, semi-hard foil and soft foil according to the state.
1 Hard foil: Aluminum foil that has not been softened (annealed) after rolling, and has no residue on the surface without degreasing. Therefore, the hard foil must be degreased before printing, lamination, coating, and can be used directly if it is used for forming.
2 semi-hard foil: aluminum foil hardness (or strength) between the hard foil and the soft foil, usually used for forming.
3 soft foil: aluminum foil which is softened after being fully annealed after rolling, the material is soft and there is no residual oil on the surface. Soft foils are used in most applications, such as packaging, composites, and electrical materials.
