For many years tea was mainly shipped in wooden ‘chests’ or boxes linedwith aluminium foil for protection. Now aluminium foil for food packing plays a big part inretail packaging – bringing fresh, aromatic teas to the discerning public.
Aluminium is used for packaging as it is highly malleable and can be easily converted to thin sheets and can be easily folded, rolled and packed. aluminium foil for food packing 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.
The purpose of aluminium foil for food packing is to make long-life packs (aseptic packaging) 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.
In addition other powdered or ‘instant’ drinks such as drinking chocolateare enjoyed in perfect condition despite a sometimes long storage period thanks to alufoil.
