An aluminum alloy plate is stretched between two rollers under high pressure to form a foil. Very thin foils are converted using roller-cut machines. For the production of aluminum packaging, most often used are pure aluminum or xxx1, xxx3 and xxx8 alloys containing iron, silicon, manganese and copper. The heated aluminum is wrapped in sheets with thickness between 2 and 10 mm. Then these sheets are converted into aluminum foil with the required thickness.
