Why is aluminium foil is used in packing food.
Aluminium is used for packaging as it is highly malleable: it can be easily converted to thin sheets and folded, rolled or packed. Aluminium foil acts as a total barrier to light and oxygen (which cause fats to oxidise or become rancid), odours and flavours, moistness, and germs, and so it is used broadly in food and pharmaceutical packaging, including long-life packs for drinks and dairy goods, which allows storing without refrigeration. Aluminium foil containers and trays are used to bake pies and to pack takeaway meals, ready snacks and long life pet foods.Because of its brilliant impermeability to water vapour and water, aluminium foils help to store food for prolonged time periods. Moreover, because of this wonderful property, aluminium helps to maintain the freshness of foods over long time periods.
