The Aluminum Foil is a continuous web of aluminum metal rolled to thickness ranging from 0.005 mm to a maximum of 0.15 mm. Foil is available in many forms, Le., hard, soft (annealed), lubricated, non-lubricated plain, coated, colored, printed, embossed and laminated to a variety of paper and synthetic films.
As compared to other flexible packaging material, aluminum foil has proved to be the superior material as far as protection of material, convenience in usage and surface finish are concerned. However, in India, Aluminum Foil has proved to be costly because of higher price of basic material and higher excise duty. Many a time, it is not available in requisite quantity.
