According to EN standard, foil thickness ranges from 0,006 mm to 0,200 mm, thicker foil is referred as strips and sheet metal. Impol Foil Plant manufactures foils of different purity or from different alloys, harmonized with international standards.
Most of foils are made according to EN standards, where EN 573-3 standard determines chemical composition, EN 546-2 mechanical properties, EN 546-3 dimensional tolerances, and
EN 546-4 other properties.
Alloys used in manufacturing raw aluminium foil are presented in the table below, compared also with other standards:
