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: USA main battle tank has 5 inch thick aluminum armor.U.KAluminum naval vessels burned after explosive impactsdelivered by South American military.
- Aluminium is classified as a class 4 flammable solidWhen oxidation occurs Al releases a lot of energyThis is not usually an issue with solid Al but Al powers can become explosive when they start to oxidise; this is due to the higher surface area of powdered AlHowever, I would expect that there is a possibility that this could occur with solid Al, if enough energy was present; ie when attacked by an explosive armament; esp if it was a high temp incendiary device.
- Q: My daughter's 1st Birthday Party is Saturday, and this is my first time baking a birthday cakeI won't have a lot of time on the day of the party to bake her cake and 40 cupcakes, so I want to do all of the baking tonight (Thursday) and decorate everything on Saturday morningDo I need to freeze the cake and cupcakes or will 2 nights in the refrigerator be ok? If I do need to freeze them how long will it take for them to defrost before I can ice and decorate them?
- i think its aluminum Al and the charge on it is +3
- Q: I have three questions this is only for people that know what I am talking aboutFirst can I make the Volksplane using aluminum tubes? Second should I build a two seat or one and would it cost more for a two seat? Lastly where can I get the plans for free?
- Plans for free are not likely unless, like the other guy said, you can find a friend that doesn't want/need theirs any moreOne or two seats is the ultimate homebuilder questionIf you build it with tubing, it's not the Volksplane any more but your own designFind your local EAA chapter and try those questions there.
- Q: Its the one that is aluminumit has 500gb and the screen is 17in.My friend is selling it for 600 .is it a good deal? if so how much can i resell it for?
- Had a sniff round and there's one going for $2300 on Amazon so you could take a gamble.
- Q: Used in aluminum foil and foil barbecue that better?
- Unofficial Forum on Hongkong Youth Award Program welcomes all friends to share exam notes. Director of Taipei Chang Gung Memorial toxicology Lin Jieliang pointed out that the tin or aluminum metal material may cause damage to the human body, such as tin will stimulate the stomach, causing similar symptoms of gastroenteritis; have been found that aluminum may be a key cause of senile dementia, some of the more kidney patients may cause anemia and bone lesions in animal; body experiments confirmed that aluminum can cause nerve poison. Lead to a rise in metal content in food
- Q: Every time I make them I use a low heat and they just end up strinking and REALLY crunchyI don't want crunchy I want chewy but well doneHow do resteraunts do it?

- Q: what are some easy ways to make a solar cooker for a science project? it needs to be relatively easy and actually able to bake somethingi can't use a magnifying glass.
- make a parabolic reflector out of aluminum foil and put the hot dog at the focusParabolic reflectors are difficult, but a hemisphere is a good approximationImagine a sphere and chop off 1/3 of itForm a piece of Al foil to this shapeUse a bowl or a beach ball as something to form the Al foil onUse heavy foil or use 3 or 4 layers so it holds it's shapePut it in the sun, pointing towards the sun, and put a marshmallow at the focal point, which you can find by trial and errorIf you formed it from a beach ball, think of where the center of the beach ball is, that would be the focus.
- Q: I have a survival knife that came coated, but I'd rather have it be bare and polished metal, so that the blade could be used as a reflective signaling deviceAs far as how to achieve that, I know it would be fairly simple using a dremel tool- sanding off the coating then using the polishing brush and polish paste to bring the metal to a shine, but I want to make sure thats not going to affect my knife in any other way I can't imagine loss of the coating would weaken the metal at all, and yea I guess it would show dirt and such easier but that doesn't hugely concern me.And I know the coating isn't too thick and will come off easily b/c its already starting to wear off on parts on the blade that tend to rub going in and out of the sheath
- No, I wouldn'tIf you polish off coating from a knife blade it will probably rust more easily.carry a small mirror or aluminum foil for a reflective signaling device.
- Q: A 2.0 mm diameter aluminum ball is charged to +58 nCWhat fraction of its electrons have been removed? The density of aluminum is 2,700 kg/m3.
- Since the atomic weight of aluminum is also very close to 27, the 2700 kg is very close to 100,000 molesTherefore, each 1 m^3 of aluminum is 100,000 times Avogadro's number of atomsNumber of atoms in each 1 m^3 will be 6.0 x 10^23 x 100000 6.0 x 10^28Number of electrons in each 1 m^3 of aluminum will be 27 x 6 x 10^28 1.6 x 10^30Volume of a 2.0-mm-diameter ball is (4/3)(pi)(0.002 m)^3 3.35 x 10^(-8) m^3 Number of electrons in this volume will be (3.35 x 10^(-8) m^3)(1.6 x 10^30/m^3) 5.36 x 10^22 How many electrons are required for a charge of -58 nC? That would be 58 x 10^(-9) C/(1.6 x 10^(-19) C) 3.6 x 10^11 So the fraction removed is 3.6 x 10^11/(5.36 x 10^22) about 7 x 10^(-12), that is to say, 7 trillionths, or 1 out of every 150 billionNot a whole lot!!!
