The state of the aluminum foil

Aluminum foil can be divided by state hard foil, semi-hard foil, a quarter soft foil, foil and three-quarters foil. 1, hard foil ( H18 state) : after rolling without softening ( Annealing) And aluminum foil, not by the degreasing process, there are residual oil on the surface. So hard foil must be degreased before printing, composite, the coating processing, if used for shaping is used directly. Applications have medicinal foil processing aluminum foil containers, decorative foil, etc. 2, semi-hard foil ( H14, H24 condition) Aluminum foil (hardness: Or intensity) In hard foil and soft foil between the aluminum foil, usually used for processing. Applications such as air conditioner foil, cap material. 3, soft foil ( O state) : after full annealing after rolling and soft aluminum foil, material is qualitative soft, surface without residual oil. Most current applications, such as packaging, composite, electrical material, use soft foil. Applications have any food, cigarettes and other composite packaging materials, electrical equipment industry, etc. 4, a quarter of hard foil ( H12, H22 state) : when the tensile strength of the aluminum foil between soft state foil and semi-rigid foil aluminum foil. Applications such as air conditioner foil. 5, three-quarters of hard foil ( H16, H26) : when the tensile strength of the aluminum foil between the hard foil and semi-rigid foil aluminum foil. Applications such as air conditioner foil, works for aluminium foil.
