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:what's the difference between the knocking voice of aluminum sheet and stainless steel?
The voice of aluminum sheet is toneless, and the voice of stanless steel is more crisp.
Q:why can't aluminum sheet burn after polishing?
because aluminum will rapidly formulate dense oxide film once being exposed in air, oxide film will generate after polishing, it can't burn.
Q:How does aluminum foil tube specifications can be classified?
It is a kind of building materials,using thin steel as skeleton, packaging with aluminum foil.It can be used in the ventilation of fhigh-rise buildings like used in central air-conditioning. The other kind is made by stuffing glass wool between the two layers of alumnium foil on both sides to preserve the internal heat. So, it is also called heat preservation tube. It can be divided into 10 centimetres, 15 centimetres and 20 centimetres.
Q:Which is better, tin foil anti-moisture pad and aluminum foil anti-moisture pad?
It is suggested to bring PVC anti-moisture pad in cold and damp places instead of aluminum foil anti-moisture pad. But aluminum foil anti-moisture pad is enough when you go to such places as park with cement Floor.
Q:What's the application of double-sided conductive aluminum tape?
Aluminum foil tape with all the seams of the aluminum foil composite paste, the seal and insulation nails puncture wounds repair. Aluminum tape is widely used in refrigerator, air conditioning, automobile, petrochemical, bridge, hotels and so on. Application: 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.
Q:As for the use of aluminum foil paper,which side is the front side?which side do we use when using the baking oven?
My mouth is watering when having teppanyaki.The back side(bright side) faces the outside to wrap the food.when cooking some dishes(fried cod fish),you need to punch small holes with toothpick in case of the aluminum foil broken and the liquor splashing.Hope you enjoy cooking.
Q:What causes the pinholes of the aluminum foil?
Generally believed that the main pinhole and gas content, inclusion, segregation and related compounds. Take effective molten aluminum purification, filtration, helps to reduce grain refinement are pinholes. Of course, using other means to improve the alloying material hardening properties also help reduce pinholes. High-quality hot-rolled aluminum foil rolling 6μm pinhole in 100 / m or less. When the casting material when better purification, 6μm foil pinholes 200 / m or less.
Q:Is aluminum foil rubber & plastic thermal insulated material expensive?
Aluminum foil rubber & plastic thermal insulated material is expensive. 1: Huamei B1 Aluminum Foil Rubber & Plastic Thermal Insulated Material 980 yuan/m³. 2: B2 Aluminum Foil Rubber & Plastic Thermal Insulated Material 550 yuan/m³, factory price 3: Shenzhou B1 Aluminum Foil Rubber & Plastic Thermal Insulated Material 9000 yuan/m³ 4: B2 Aluminum Foil Rubber & Plastic Thermal Insulated Material 550 yuan/m³. The above prices are from Internet and for your reference only.
Q:How many companies have used aluminum coil?
Too many. All the companies who make the aluminum products you have seen in daily life have used it. So it is hard to explain.
Q:Aluminum foil and fold thickness difference is caused by what?
A roll of aluminum foil rolling up to tens of meters, rolling up to about 10h, with time, the difference between thick, very easy to form, and the means for adjusting the thickness of only tension speed. These factors have caused difficulties controlling the thickness of aluminum foil rolling, so the real difference in thickness control less than 3%, a number of conditions need to ensure, rather difficult.
