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%.

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:Why is the second ionization of silicon less than that of aluminum?
In order to move aluminum to its second ionized state, an electron must be removed from a full and stable 3s orbitalWhen silicon is ionized a second time, an electron is removed from the 2p orbital leaving the 3s orbital filledThis requires less energy.
Q:How do I cook with aluminum foil?
Step 1: Place chicken in aluminum foil, make sure edges of foil are folded up so it doesn't drip all over the ovenStep 2: Place in oven Step 3: take it out when it is doneIt is literally just like cooking in a pan, but with less cleanupYou may want to season the chicken or whatever first.
Q:How to keep frozen currypuff fresh and still good for 2 months?
It's all in the freezer wrapping, wax paper so it won't stick to the puffs, cling wrap for freezer burn and then warp that inside aluminum foil or freezer paper, inside of a freezer baggyTwo months is a long time for puff's.
Q:Why should we recycle?
Sure, just be careful in the spacing.
Q:Chemistry help! I think the answer is A but dont know.?
not at all today most blue collar jobs take much more training than 40 years ago skilled trades even more so
Q:Aluminum foil boat building?
Here's my 2 cents, for what it's worth: I would make the boat with a shape similar to that of a juicer (the glass thing used to squeeze oranges) but with higher sides (and not as big a dent in the middle)Form the center of the foil into this shape, and roll up the edges to make a rimDon't flatten as you roll, you want the rim to be as rigid as possible(You may find that flattening the rim horizontally gives more strength; experiment!) You should wind up with a bowl that has a hump in the centerThe hump helps keep the weight of the marbles toward the edges, rather than in the center (where they would tend to collapse the ring)If you get to put the marbles in yourself, put the first ones in so they form a ring around the outer edge and build on thoseThis will also trap some air under the center cone which should help with buoyancy and stabilityTest your design and tweak it! Good luck!
Q:What the the dangers of microwaving food wrapped in foil?
Q:Passive cooler using layers of blackened foil and evaporative cooling.?
Although I'm familiar with what you are trying to do (and it does work) I don't know any way to do it light weight The clear sky is really cold and heat will radiate offBut if the air is warm you need a window to prevent convection (air circulation) from defeating your purpose If it gets cloudy and warm (as it will in some areas) you have a problemThere are naturally occurring ice caves where there is sufficient thermal mass that radiative cooling can keep water frozen year roundI think just super good insulation is the biggest keyIf you can open a box to the night sky when the air is cool and close it up during the dayEvaporative cooling is my favoriteIt does require that the air be reasonably dry - not good in humid climatesIt can be effective with something a simple as a wet towel, but a filter pad that air can flow through while wet is the best.
