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 patentshe filed between 1886 and 1903. It has consequently been suggested[by whom?] that the spelling reflects an easiertopronounce 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:Aluminium is used for the manufacture of?
Aluminum is good for saucepans because aluminum is a very good conductor of heat (and electricity as well, which is why it's sometimes used for cables/wires). Aluminum is also good for small boats and airplanes since it's a very lightweight (not very dense) metal yet still strong enough for many applications. Weight is a very important factor for airplanes and small boats. Not too sure about hospital blankets, unless you're talking about those reflective blankets but those are mainly to reflect your body heat back to you and minimize heat loss.
Q:What are two chemical reactions of aluminum?
2Al + 3H2O → 2Al(OH)3 Aluminum + Steam - heat - exothermic reaction causing aluminum hydroxide. 2Al + 3H2SO4 → Al2(SO4)3 + H2 Aluminum + Sulfuric Acid - exothermic reaction causing Aluminum Sulfate and Hydrogen Gas
Q:what's the dying temperature of aluminum-foil paper?
It depends on walking speed.If faster, 180 degree,otherwise 120 degree.
Q:Without the backing of aluminum foil and aluminum foil backing is what is the difference between what is their characteristics?
No backing: is the ordinary aluminum foil, a tin foil, such as high-grade aluminum bottle mouth. The surface has very tiny holes, easy to leak smell, but can be arbitrary shape covered in the surface of the object, very soft.A backing: in ordinary aluminum foil coated or pasted a layer of material, such as cloth, paint, paper etc.. In order to increase the intensity, reduce the leakage of aluminum foil surface caused by tiny holes. The most common is the layer inside the cigarette case. .
Q:Does the aluminum foil can be effective in the environment of temperature 430 degree?
It can endure 430℃
Q:Can aluminum foil be used in the microwave?
Aluminum foil in the microwave may not use, although supermarkets have special aluminum foil, but still be careful. Because the furnace when heating food in aluminum foil, aluminum foil in contact with the inner wall will give birth to a spark.
Q:Is it necessary to put damp proof aluminum foil in the cabinet?
The water is very necessary to foil, the other is not necessary. This is done in large cabinets, our home water tank.
Q:What is primary aluminum?
Aluminium that is produced from ore, as opposed to secondary aluminium which is produced from recycled aluminium products.
Q:Aluminum foil bag sterilization? (ADV ~ ~)
Ordinary aluminum foil bags should be cooked at high temperature, so that they can be sterilized later.
Q:How can the aluminum foil hose be connected with the toilet exhaust fan?
Use aluminum foil hose to catch the exit of exhaust fan, pay attention to the diameter must buy, right, buy small or buy too big is not good connection; and then use aluminum foil tape sealing the interface;
