8011 aluminum foils for beer bottles

8011 aluminum foils for beer bottles are used for beer and Champagne label after printed or embossed, the thickness is 0.010—0.0115mm. Whether it is made of hot-rolled or cast-rolled billets, the chemical composition of the beer is 8011 alloy. However, in the production, the actual control composition range of different manufacturers is different, and the chemical composition control range is mainly determined considered the tensile strength, elongation, pinhole and other technical indicators to meet the user’s requirements.

The use thickness of beer label aluminum foil is very thin, close to the lower limit of the thickness of the medium gauge aluminum foil. In order to obtain good deformation properties, the elongation index is relatively high in order to ensure suitable strength. Since the alloy composition, the casting process and the heat treatment process all have an important influence on the mechanical properties of the final product of the medium gauge aluminum foil, an 8000 series beer label aluminum foil having a certain strength and elongation and excellent formability is preferred. Such as the 8011 alloy with higher iron content than the industrial pure aluminum, the alloy has good rolling performance, the processed aluminum foil has less pinholes, does not crack when heat-sealed, and is also used for the production of pharmaceutical foil. 8011 alloy is generally used as aluminum foils for beer bottles, for air-conditioning foil fins, medical caps, non-air pressure drinks and anti-theft caps and wine bottle caps, and has good formability.
