Aluminium plays a majorrole in the modern world through its innumerable forms of applications- fromkitchen ware to electric conductors and from railway wagon to Appollospacecraft. Because of its intrinsic and versatile properties of lightness,strength to weight ratio, corrosion resistance, electrical and thermalconductivity, non toxicity etc., a wide range of uses has opened up for thismetal. Aluminium as a packaging material is unmatched owing to its lightweight, hygienic and non-contamination which eventually results in longershelf-life of end products.
Aluminium foil is a thinsheet of metal. As such it can be an absolute barrier to moisture, gases,odors, bacteria and moulds. The high reflectivity of aluminium ensures goodprotection against radiant heat, whilst its opacity is important in preventingdeterioration of a very large range of foods and drinks which are affected bylight. It is used for packaging and non packaging uses. The growth of this industry has been in therecent past, owing to the growing application of foil in a variety of products.
