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%.

Aluminium (or aluminum; see spelling differences) is a chemical element in the boron group with symbol Al and atomic number 13. It is a silvery white, soft, ductile metal. Aluminium is the third most abundant element (after oxygen and silicon), and the most abundant metal in the Earth's crust. It makes up about 8% by weight of the Earth's solid surface. Aluminium metal is so chemically reactive that native specimens are rare and limited to extreme reducing environments. Instead, it is found combined in over 270 different minerals.The chief ore of aluminium is bauxite.
Aluminium is remarkable for the metal's low density and for its ability to resist corrosion due to the phenomenon of passivation. Structural components made from aluminium and its alloys are vital to the aerospace industry and are important in other areas of transportation and structural materials. The most useful compounds of aluminium, at least on a weight basis, are the oxides and sulfates.
Despite its prevalence in the environment, no known form of life uses aluminium salts metabolically. In keeping with its pervasiveness, aluminium is well tolerated by plants and animals. Owing to their prevalence, potential beneficial (or otherwise) biological roles of aluminium compounds are of continuing interest.
The earliest citation given in the Oxford English Dictionary for any word used as a name for this element is alumium, which British chemist and inventor Humphry Davy employed in 1808 for the metal he was trying to isolate electrolytically from the mineral alumina. The citation is from the journal Philosophical Transactions of the Royal Society of London: "Had I been so fortunate as to have obtained more certain evidences on this subject, and to have procured the metallic substances I was in search of, I should have proposed for them the names of silicium, alumium, zirconium, and glucium."
Davy settled on aluminum by the time he published his 1812 book Chemical Philosophy: "This substance appears to contain a peculiar metal, but as yet Aluminum has not been obtained in a perfectly free state, though alloys of it with other metalline substances have been procured sufficiently distinct to indicate the probable nature of alumina."[69] But the same year, an anonymous contributor to the Quarterly Review, a British political-literary journal, in a review of Davy's book, objected to aluminum and proposed the name aluminium, "for so we shall take the liberty of writing the word, in preference to aluminum, which has a less classical sound."
The -ium suffix conformed to the precedent set in other newly discovered elements of the time: potassium, sodium, magnesium, calcium, and strontium (all of which Davy isolated himself). Nevertheless, -um spellings for elements were not unknown at the time, as for example platinum, known to Europeans since the 16th century, molybdenum, discovered in 1778, and tantalum, discovered in 1802. The -um suffix is consistent with the universal spelling alumina for the oxide (as opposed to aluminia), as lanthana is the oxide of lanthanum, and magnesia, ceria, and thoria are the oxides of magnesium, cerium, and thorium respectively.
The aluminum spelling is used in the Webster's Dictionary of 1828. In his advertising handbill for his new electrolytic method of producing the metal in 1892, Charles Martin Hall used the -um spelling, despite his constant use of the -ium spelling in all the patents[58] he filed between 1886 and 1903. It has consequently been suggested[by whom?] that the spelling reflects an easier-to-pronounce word with one fewer syllable, or that the spelling on the flyer was a mistake.[citation needed] Hall's domination of production of the metal ensured that aluminum became the standard English spelling in North America.
- Q: What is the material of aluminum foil roll?
- Aluminum foil roll is a kind of common rollThe roll is an important part of a rolling mill on a steel mill, rolled and rolled by the pressure produced by rolling a pair or a set of rolls. It is mainly affected by static and dynamic loads, wear and temperature changes during rolling.According to the general manufacturing process, due to the chilling effect of metal layer is white tissue (substrate + carbide) roll called chilled cast iron roll; with the above method, but increasing the iron carbon equivalent and mottled structure (substrate + carbide + graphite) roll called infinite cold and hard cast iron roll."Infinity" - derived from the English word "indefinite", is originally defined as "indefinite". It means that the quench layer has no definite boundary on the fracture surface and has been misinterpreted as "infinite". By using the sand lined metal mold and continuing to increase the carbon equivalent, the roll of coarse hemp can be obtained, which is called semi chilled cast iron roll. In all the tissues of the above-mentioned varieties, the graphite is spherical, called the spheroidal graphite cast iron roll, and the compound cast roller is compounded with the word "compound".
- Q: What's the difference between hot rolled aluminum foil and cold rolled aluminum foil?
- The aluminum foil mill only consists of rough rolling, medium rolling, finishing rolling, without hot rolling and cold rolling.
- Q: I've been trying for a while to think of ways to make a good deal of money, but i can't think of anything that would work.(car-wash, moving lawns, and walking dogs won't work)
- Pointy' is correct except when you divide over the 1 minute, it's supposed to be in secondsSo divide by 60!
- Q: what is oxides means?
- No, because the foil is a vapor barrierIf you add insulation on top you will gather moisture which will cause dripping and moldSon is in insulation business.
- Q: What material is the best insulator: paper, cotton or aluminum foil? Does all this do something with density?
- Density is not directly linked to conductivityThey're both innate properties of a materialIt's true that denser materials tend to be better conductors but not alwaysAluminum happens to be way denser than paper or cottonWhat makes metals so great is that they don't hang on to their outer electrons very wellThere's this sea of loose electrons just naturally sitting there in any metal and their looseness makes them easy to push around with a battery.
- Q: do you think it would be ok if i made my christmas banana bread now and froze it until until i gave them as gifts? thanks soo much!
- yes you should be okay to freeze your breadI would the loaves really well with cling wrap (saran wrap.some form of cling wrap!) and then wrap them with aluminium foilIf they will fit, you could go an extra step and put them in one of those gallon sized freezer bags that has freezer lock that is supposed to keep the food from getting frost bite.

- Q: Is my microwave OK to use? I tore off that cardboard inside cover?There was a piece of cardboard on the right side inside wall of my microwave (and every one i have ever seen) and it covers a vent that I think the cooking tube is behind.Anyway I tore that off and now I am worried that it may not be safe anymore.babasicallyhe reason i tore it off was because out of nowhere sparks came out of the microwave and it came from the cardboard bitthe cardboard was cocoatedith alALUMINIUMnd i think the that outside coating of plastic got eaten away from all theses years of use and i think it finally reached the aluminium coated side.
- i could recommend calling your vet, and he/she would be able to be waiting that might assist you get him on the outstanding supplements, and the outstanding feeding time tableThe vet might recommend many things, so i could additionally attempt to maintain up some money in simple terms in case it quite is costlyWith older age, horses are on occasion stressful to maintain weight onin case you reside in a less warm climate, get a blanket for him to be sure he would not get the chills.
- Q: Please help me explain why this meal wont work.
- Simple one time bottle bowl, where you take a bottle take off the cap and put aluminum foil on in the cap spot and poke like 10 little holes with a toothpick in the foil, then make two holes in the middle of the bottle(one mouthpiece, and once choke)Then Put your mouth on one hold and put a finger on the other and light the weedDon't use that method too often because it's not good for your heath to smoke out of aluminumYou tube simple weed bowls, you will get a lot of nice ways like this one, apple pipe, water bong, etcI would recommend buying a glass bowl though.
- Q: which stores most heat and holds it the longestfor example if you heat any of the below which will release the heat that it holds the slowestmore explicitly stated Which takes the longest to return to room temperature and please explain whycotton paper aluminum
- water is one of the highest specific heat of water is 4.186 kJ/kgC or 4186 J/kgC metals are not nearly as high, for example specific heat of Aluminum is 900 J/kgC and paper and cotton are even lower specific heat is a measure of how much energy (heat) it takes to raise the material in temperatureThermal conductivity is how it moves heat from one end to the other.
