Now keep your food fresh from your kitchen to your fridge to your office by using this amazing aluminum foil that prevents your food from getting cold. Perfect for party use where you can protect your food from dust by covering it with this aluminum foil and keeps it warm for a long period. The aluminum foil can be used for baking purposes, so grease it with oil and bake your cakes, muffins or lasagna.
Chocolates in aluminium foil packaging 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 (aseptic packaging) for drinks and dairy goods, which allows storing without refrigeration. Aluminium foil containers and trays are used to bake pies and to packtakeawaymeals, ready snacks and long lifepetfoods.
Aluminium foil is widely sold into theconsumermarket, often in rolls of 500mm (20in) width and several metres in length.It is used for wrapping food in order to preserve it, for example, when storing leftover food in arefrigerator(where it serves the additional purpose of preventing odour exchange), when takingsandwicheson a journey, when baking, or when selling some kinds oftake-awayorfast food.Tex-Mexrestaurants in theUnited States, for example, typically provide take-awayburritoswrapped in aluminium foil.
Aluminium foil is also used forbarbecuingdelicate foods,such as mushrooms and vegetables. Using this method, sometimes called ahobo pack, food is wrapped in foil, then placed on the grill, preventing loss of moisture that may result in a less appealing texture.
As is the case with all metallic items, aluminium foil reacts to being placed in amicrowave oven. This is because of theelectromagnetic fieldsof the microwaves inducing electric currents in the foil and highpotentialsat the sharp points of the foil sheet; if the potential is sufficiently high, it will causeelectric arcingto areas with lower potential, even to the air surrounding the sheet. Modern microwave ovens have been designed to prevent damage to thecavity magnetrontube from microwave energy reflection, and aluminium packages designed for microwave heating are available.
Heavier foils made of aluminium are used for art, decoration, and crafts, especially in bright metallic colours. Metallic aluminium, normally silvery in colour, can be made to take on other colours throughanodisation. Anodising creates an oxide layer on the aluminium surface that can accept colored dyes or metallic salts, depending on the process used. In this way, aluminium is used to create an inexpensive gold foil that actually contains no gold, and many other bright metallic colors. These foils are sometimes used in distinctive packaging.
