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:Does the waterproof effect good if the SBS roll of aluminum foil used in conjunction
The same material should be used in conjuction and the waterproof should be applied to the the construction.
Q:can use aluminum foil to shield the loudspeaker box wire?
It does little help. According to experts, the noise of replaying results from external RF electromagnetism frequency. Therefore, using aluminum foil to shield louder speaker box wire will make the music quieter. Actually after listening to LP record, vinyl record or CD, you will find the background of vinyl record is quieter than that of CD. This is because the error during reading CD causes the noise. However, the noise after being amplified and replayed is considered to be resulted by RF. Another proof is that the conduction of silver is quicker than that of copper and the noise of silver loudspeaker wire is more obvious than that of copper loudspeaker wire. Of course, the noise of loudspeaker produced by multifilament is something else.
Q:Performance of aluminum foil and how does it insulate heat? Describe it precisely and in detail and better give the source
Aluminum foil is widely used in fields like food, beverage, cigarette, medicine, photographic plate and family daily necessities as packaging material; electrolytic capacitor material; insulation material for building, automobile, ship and house; and decorating metallic yarn, wall paper, all kinds of stationery and printings as well as decoration and trademark of light industrial products for its nice properties. Among all these applications, aluminum foil used as packaging material can maximize its characteristics. Aluminum foil material is soft metal film, which is not only moisture-proof, air sealing, light shading, wear resistant, fragnance-holding, non-toxic and tasteless but also has a silvery luster and is easy to print all kinds of beautiful patterns of all colors, so it is easier to be favored. Especially after aluminum foil composited with plastic and paper, it integrates shielding of the aluminum foil, strength of paper and thermal insulation of plastic, and further improves the shielding function of aluminum foil tape as packing material from moisture, air, ultroviolet rays and bacterial, which has greatly expanded the application market of aluminum foil. The packaged items are perfectly protected because the light, moisture and air are completely insulated by packaging material. Especially the package for some steamed food use a kind of composite aluminum foil material which can ensure the food does not spoil for more than a year. Besides, it is easy to be heated and opened up, which is very popular with customers.
Q:Does the aluminium paper can be used in the micro wave oven?
Yes. Any kinds of aluminium foil can be used in the micro wave oven.The aluminium foil used in the micro wave oven is selled in the supermarket! Control the temperature! The food should be heated balancedly and prevent nutrients loss.I usually use the aliminium foil when cooking the beer fish. Aluminium foil:high temperature cooking aluminium foil、low temperature aluminium foil,ect. The aluminium foil wrapped food should be put into the oven for heating. The use should be avoided if the aluminium foil have the spark when contact to the interior wall of the oven.
Q:Does some one has ever used the aluminium foil paper to keep the house roof from overheat? How about the effect of this method?
if you consider the high compression capability, you can use the honeycomb pannel as your roof. It is environmental friendly, economically,anti- heat and anti-moisture.
Q:Why the double-sided self-adhesive foil easily layered and very smelly.
Generally speaking, both sides of double-sided self-adhesive are usually isolating membrance, not aluminum foil. Both sides need to be uncovered to use as pre-installed and inverted adhered. If one layer is aluminum foil, it's one side self-adhesive. If it's smelly, it is must made of inferior raw material with one industrial waste as self-adhesive material. This kind of raw material has strong cancerogenic effects.It's also very smelly in the making process. Campus surrounding plants also die because of the smell. What's more, its waterproof effect is also decreased. You would better not to use it.
Q:Whether abandoned aluminum foil has recovery value?
Waste aluminum foil can be produced PAC. PAC is commonly used inorganic polymer flocculant. The sources for developing a wide range of raw materials to produce PAC of a foundation. In particular, the production process is varied, the development of a PAC for the convenience. International and domestic inorganic polymer flocculants has a larger scale production and application of theoretical research has also made in-depth development.
Q:Adhesion of aluminum and glass
Firstly, clean them up and then use bi-component polyurethane structural adhesive to spice them. Make the appearance of fiberglass polished and clean.The appearance of aluminum foil would better be anodized to make it have good tenacity and strength.
Q:What's the minimum length of aluminum foil a roll?
A roll of aluminum foil is 12000meters and the aluminizer is 6000meters.
Q:How to use aluminum tape?
Aluminum tape is suitable for all kinds of transformers, mobile phone, computer, PDA, PDP, LED displays, notebook computers, copiers and other electronic products in which electromagnetic shielding is required. Decorative aluminum foil is an aluminum-plastic composite material used for decoration by taking advantage of good colorability and high heat reflectivity of aluminum foil. It is mainly used in building, furniture decoration and part of gift box packaging.
