Samkvæmt lögun, álpappír má skipta í rúlla álpappír og álpappír. Flest djúpvinnsluefni úr álpappír eru afhent í rúllum, and sheet aluminum foil is only used on a few handicraft packaging occasions.
According to the state, álpappír má skipta í harða álpappír, hálfharð álpappír, and soft foil.
①Hard foil: The aluminum foil that has not been softened (annealed) after rolling, without degreasing treatment, has residues on the surface. Þess vegna, hörðu álpappírinn verður að fita fyrir prentun, lagskiptum, 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. Efnið er mjúkt og engin leifar af olíu á yfirborðinu. Most of the current application areas, such as packaging, lagskiptum, electrical materials, o.s.frv., use soft foils.
