So hard foil in the printing, bonding, coating must be degreasing before treatment, if used for forming can be used directly.

2.Semi-hard foil: aluminum foil hardness (or strength) between the rigid foil and soft foil foil, usually used for forming processing.3.Soft foil: after rolling through the full annealing and soften the aluminum foil, soft material, the surface without residual oil. Most applications, such as packaging, composite, electrical materials, etc., use soft foil.
