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: Buying Schwinn 564 qwerty?
The bike has Biopace chainrings which are not supposed to be round, nothing to worry aboutThe price is still a bit high, the components on the bike were a couple of notches below 105 at that time, but reliable and serviceableIf the chain has a stiff link, check it and the cassette very carefully, if you have to replace them it could cost you an extra $60-$70 in partsI had a bike with similar components back about then and it stood up through many years of heavy use.
Q: We are a factory in China,Our main products are aluminium profilesSuch as aluminium door,aluminium window,aluminium heat sink for electricial products,aluminium tube pipe, aluminium balustrade,etc!We can produce aluminium products with different kinds of surface treatments and different colours!
A chicken is not going to brown in 30 minutes, and you are using way too much heatMore heat doesn't mean faster cooking; sometimes it only means that you burn the outside while the inside isn't done yetTry 350F for 20 minutes per pound, and baste with the melted butter from the bottom of the pan every 10 minutes or soDid your recipe say to roast, or did it say to broil for 5 to 7 minutesbroiling probably would brown the skin in 5 to 7 minutes, because it's top heat onlyRoasting or baking uses bottom heat.
Q: Hey guys, so last year my friend of mine tried an experiment to increase the range of his usb wireless cardThe basic concept was to get the usb card and basically turn it into a mini Satellite as in he drilled a hole into he bottom of a large plastic bowl, coated the inside in aluminum foil, and super glued the usb card inside so that the the back chord would come out the other endhe then mounted it on a tripod he foundthe end result was that he was able to get signals from networks about a mile awayi don't remember the exact way he did it, so if any of you have experimented with something like this or something similar can you please tell me? I'm looking for a way to get some sort of internet access at my school form my laptop, thanks again ]
You can do a Google search for cantenna and find all sorts of interesting ways to make point-to-point unidirectional wi-fi antennasAs an experiment, some workers in our electronic maintenance shop used a big baked beans can, calculated the proper length from the back of the can and proper length of the probe inside the can, and got pretty good range (two bars at three blocks) from an 802.11B network card.
Q: I have plans for a picnic in the summer in central parkI will be preparing a fruit salad that may be out of the fridge but wrapped up for 4 hoursI already have a thermal bag, aluminum foil and i can make ice packsIs this adequate protection? I will be on the train for 2 hours, than taking a 10 minute subway ride than probably be outside for an hour and a half before unwrapping the fruit saladIs there anything i can do to make this fruit as fresh and cold as possible?
I wrap my head of lettuce w/ aluminum foil for lettuce in the fridge and it lasts me super long!
Q: I need to get butcher paper for this project I'm working on, but everywhere i called they only have it sold by the rollDoes anyone know where I can buy it locally by the yard/ foot? I live in Fremont, California.
You want the white slick stuff? If 12-18 wide, you should be able to buy it in most grocery stores with the aluminum foil as freezer wrap If you want it wider, go to the butcher shop in the grocery store and ask politely if you can get a couple of yards of the paperMost places will pull off 6 feet or more and roll it up and hand it to you If you mean the brown paper, go to package mailing places in office supply and free standing (Mailboxes, Etc.) and they will usually have a 3' wide roll on a huge tear off dispenser and will give or sell you yardsThis is sold in narrower rolls in packaging/shipping supplies in office stores.
Q: I have aluminum and chlorine to form a compound.Aluminum loses 3 electronsDoes the chlorine gain 3 or just 1?
Both atoms in the compound must gain the octet and become stable fo it to become a compoundFor Aluminum to react Chloride there must be 3 chloride atoms for every Aluminum atomBecause Aluminum has a valency of 3, so it needs 3 electrons to fill its outer shellAnd Chloride needs one electron to fill its outer shellSo To make Aluminum Chloride there must be 1 Aluminum and 3 Chloride atoms per molecule.
Q: Aluminum reacts with chlorine gas to form aluminum chloride2AL(s)+3CL2(g)arrow2ALCL3(s)You are given 19.0g of aluminum and 24.0 g of chlorine gas.1 If you had excess chlorine, how many moles of aluminum chloride could be produced from 19.0g of aluminum?2 If you had excess aluminum, how many moles of aluminum chloride could be produced from 24.0g of chlorine gas,CO2?
