Aluminium has been used commercially since nineteenth century. It is plentiful availability and its characteristics have changed our way of life. Aluminium is widely used for packaging, building, transportation and Electrical Devices.
Aluminium foil (Alufoil) is a very thin sheet of aluminium ranging from about 0.006 mm (6 µm ) to the upper ISO defined limit of 0.2 mm (200 µm). Aluminium foil can be used for various applications and economical, light, hygienic, non-toxic, and very conductive to heat as compared to other materials.
Aluminium foil provides highest barrier against moisture, oxygen, light and contaminant. It extends shelf life of products for many months while keeping the aroma inside and preserves the good content of food and beverages.
Supra Aluminium produces top quality of light-gauge aluminium foil that complies with US FDA requirements for direct food contact packaging material. The total lead, cadmium, mercury, magnesium and hexavalent chromium content in our aluminium foil complies with the requirement of European Council Directive 94/62/EC.
