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:Aluminum vs Wood?
Simply put, the risk of somebody incurring a serious injury or even death is starting to outweigh the financial benefits of using aluminum over wood. The increase of velocity of a pitched ball coming off a wooden bat compared to one coming off aluminum is tremendous. Specifically pitchers and corner infielders are put at major risk each and every time they play games against hitters using aluminum bats. Places that once thought of saving money by not having to replace broken bats are wisely chosing to put a higher price tag on a players health. It should be a universal thought, but sadly there are some who still endanger players everyday by allowing aluminum bats...they are the ones who should consider the cost of a wooden bat vs. the cost of an athletes health.
Q:What are the advantages of two-sided aluminum foil, phenolic resin and color coated phenolic resin?
Color steel phenolic board is to double 0.06mm foil, phenolic foil on one side of the aluminum foil into 0.2mm color steel plate, so as to increase the phenolic resin plate impact resistance, not easy to pierce.
Q:can a person absorb aluminum through the skin, by handling solid aluminum?
The food thing is true...don't do that If your talking about Aluminum like in can, rods, screws, etc. Your ok...its an alloy. Now If you talking about Lab quality refined pure Al+3... that oxidizes fast enough that you cam see it turn from silver to white before your eyes. I've seen Pure Al stored in oil filled glasses before, but I used it in small cubes that just had to have the outer layer of oxidized stuff shaved off in oxygen free glove boxes. That stuff might dry your hands a bit. So no worries.
Q:What is the so-called aluminum tube in the air conditioner?
Hello! Refers to the internal air conditioner and the external machine connecting pipe, the middle of the connecting pipe is an aluminum tube, both ends are made of copper, also known as the aluminum plastic pipe. At present, only GREE and the United States all use pure copper connection tube, other brands only high-end machine only use pure copper connection tube, the ordinary model is the aluminum plastic tube. I hope my answer can help you!
Q:Regarding the wall thickness of aluminum alloy profiles, are there any standards in the country?
For the main force components of aluminum alloy curtain wall, such as column, transverse material and so on. Such as closed hollow profiles, the wall thickness of not less than 3mm, if the solid section (or known as non closed profiles), the wall thickness of not less than 2.5mm. The state has standards for curtain walls.
Q:polish aluminum on my motorcycle?
MOTHERS okorder.com one to do the polishing....then use a fresh one to buff the aluminum. Trust me on this one.....this is the ONLY polish I use on custom bikes.....with this stuff, you can make aluminum look almost like chrome!!!
Q:Overview of aluminum foil
Q:What's the difference between laser cutting aluminum plate and stainless steel plate?
The aluminum plate is higher than the stainless steel reflectivity, the focal point, the power, the speed are not the same, the general carbon dioxide laser does not have the anti - reflection lens, then had better not cut the aluminum plate, easy to burn the laser internal lens.
Q:How many applications does aluminum foil have?
Q:Is it true that aluminum chloride causes Alzhaimer?
Aluminium has been established as a neurotoxin.[1] Aluminium chloride, an aluminum salt that is commonly used in antiperspirants, is also commonly used in studies on aluminium-induced neurotoxicity[2][3][4][5][6]. Aluminium itself adversely affects the blood-brain barrier, is capable of causing DNA damage, and has adverse epigenetic effects.[7][8] Research has shown that the aluminium salts used in antiperspirants have detrimental effects to a number of species such as non-human primates[9], mice[10], dogs[11] and others. An increased amount of Aluminium is also present in the brains of many Alzheimer's patients, although it is not yet known if this link is causal.[12][13] I found this for you I hope it helps. Alzhaimer is also genetic. As it says here there is a link. Among that there could be other links to this disease. The best way is to keep your mind active. Active meaning reading even as you get older. I have witness patients come in to a home facility alert and then they give up. They stop reading, interacting and using their mind. Do further research and talk to your doctor.
