Product Description:

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, it is used broadly in food and pharmaceutical packaging. The purpose of aluminium is to make long-life packs (aseptic processing|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.

Aluminium foil is widely sold into the consumer market, often in rolls of 500 mm (20 in) width and several metres in length.It is used for wrapping food in order to preserve it, for example, when storing leftover food in a refrigerator (where it serves the additional purpose of preventing odour exchange), when taking sandwiches on a journey, or when selling some kinds of take-away or fast food. Tex-Mex restaurants in the United States, for example, typically provide take-away burritos wrapped in aluminium foil.

Aluminium foils thicker than 25 μm (1 mil) are impermeable to oxygen and water. Foils thinner than this become slightly permeable due to minute pinholes caused by the production process.

Aluminium foil has a shiny side and a matte side. The shiny side is produced when the aluminium is rolled during the final pass. It is difficult to produce rollers with a gap fine enough to cope with the foil gauge, therefore, for the final pass, two sheets are rolled at the same time, doubling the thickness of the gauge at entry to the rollers. When the sheets are later separated, the inside surface is dull, and the outside surface is shiny. This difference in the finish has led to the perception that favouring a side has an effect when cooking. While many believe that the different properties keep heat out when wrapped with the shiny finish facing out, and keep heat in with the shiny finish facing inwards, the actual difference is imperceptible without instrumentation.The reflectivity of bright aluminium foil is 88% while dull embossed foil is about 80%.

Q:What is the lightest aluminum wheel set?
No, not Mavic, although they make some nice light wheelsets. The American Classic Sprint 350 is one of the lightest aluminum wheels you can buy at 1300 grams. The Easton EA90 SLX has a claimed weight of 1398 grams for the pair. I've owned both Easton (Velomax) and American Classic -- my daily rider wheels -- and have found them to both be very reliable. These weights are for clinchers. Aluminum tubulars are usually marginally lighter. Probably one of the best sources is here the Weight Weenies web site, link below. Note how much heaver the Mavic Ksyriums are than the wheels I've suggested. Oddly enough, the old SSC model weighs in slightly less than the new SL with the ground out rim. Weight isn't everything, but take it from an old guy who does a lot of riding in the mountains, it makes a lot of difference in climbing and sprinting. Stay off these ultra-light wheels if you are overweight. You'll only break them.
Q:steel motors and aluminum motors?
in a word, weight. you can loose 40% of the weight using alluminum vs steel.
Q:if you use aluminum foil for a home made pipe, why is the aluminum foil so bad for you?
Aluminum foil is coated with paint and other types of polish and what not so the stuff that is coating it melts and goes into the air so you would probably get bad fumes and get sick, I wouldn't recommend using an aluminum pipe I'd but one if I were you
Q:How aluminum foil developed in China?
Aluminum foil companies may cooperate with market research firm, the market for its full research and feasibility studies, the use of models of professional development, make the brand in the aluminum foil market segments. Although the new lateral aluminum foil market is small, but the longitudinal extension of industrial chain, will produce aluminum material into end products, relying on high-value-added products can offset the lack of professional capacity size of the market, relying on specialized brand competitive advantage, still to obtain better operating efficiency.
Q:How many times can aluminum,plastic and glass bottles be recycled?

Q:What are the differences among aluminum foil,pet,and hologaram paper
The aluminum foil is pressed and extended by pure aluminum;PET is a kind of plastic polyester film; hologram paper is made by PET film through processing and painting a layer and pressing,then the electroplated aluminum layer be composited with the paper and last remove the PET.
Q:what's the dying temperature of aluminum-foil paper?
It depends on walking speed.If faster, 180 degree,otherwise 120 degree.
Q:What exactly is the bright and foggy surface of the foil in the barbecue?
The foil is placed mist side barbecue food is high temperature resistant surface by electric degree is not high temperature baking emit metal toxin yc1962... Opinion...
Q:Are there any differences between the foil used for lithium-ion batteries and the aluminum foil for supercapacitors?
A lithium battery is a battery, and a supercapacitor is a capacitor. Batteries and capacitors are two entirely different electronic components, and there is no comparability.
Q:Aluminum Outlet/Receptacle?
Try marine supplies. The ships I worked on had aluminium alloy power outlets and light switches. The bodies need to be earthed though.
