Podle tvaru, hliníkovou fólii lze rozdělit na hliníkovou fólii v roli a hliníkovou fólii. Většina vlněných materiálů pro hluboké zpracování hliníkové fólie je dodávána v rolích, and sheet aluminum foil is only used on a few handicraft packaging occasions.
According to the state, aluminum foil can be divided into hard foil, semi-hard foil, and soft foil.
①Hard foil: The aluminum foil that has not been softened (žíhaný) after rolling, without degreasing treatment, has residues on the surface. Proto, the hard foil must be degreased before printing, laminace, and coating, and it can be used directly if it is used for forming.
②Semi-hard foil: Aluminum foil whose hardness (or strength) is between hard foil and soft foil, usually used for forming.
③Soft foil: Aluminum foil that has been fully annealed and softened after rolling. Materiál je měkký a na povrchu není žádný zbytkový olej. Most of the current application areas, such as packaging, laminace, electrical materials, atd., use soft foils.
