Description/ Specification of Aluminium Foil
Aluminium Foils are very thin metal leaves up to thickness of 0.2 mm. In the lower side thickness can be as low as 6 micrometers. To make the thin foil more stable, it may be laminated to materials like paper or plastic. Aluminium foil is produced by rolling ingots cast from molten aluminium and further re-rolling is done to achieve the required thickness. Aluminium foils have several desirable properties like resistance to light, moisture and bacteria. It also prevents ingress of Oxygen. Food wrapped or packed in it stays fresh and does not become rancid due to oxidation of fats. It also prevents the odour from spreading. It is nontoxic and can withstand a wide range of temperatures spanning that in deep freeze to the temperature in microwave oven. Other useful properties are light weight. corrosion resistance, ease of lamination, and flexibility. All these makes it the perfect choice in food and pharmaceutical industry for packaging. It is also used in doing aseptic packaging for storing food material for a long time without refrigeration. It is used in packing of chocolates, instant snacks, pet foods, dairy products, cakes etc. Aluminium foil rolls are used for packing cooked foods to take them in work place or outdoors. Apart from the above applications, aluminium foils find wide use in heat insulation, radiation shield and cable liners. Heavier foils are used in forming bright metallic coloured foils through a process called anodization and subsequently used in art and craft and also in decorative packaging. Aluminium foils are also used to protect the rock samples collected from field by geochemists as they prevent ingress of organic solvents or traces of plastics from contaminating the samples
