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 national standard for aluminum tape?
Aluminum foil tape with all the seams of the aluminum foil composite paste, the seal and insulation nails puncture wounds repair. It is the main and accessory material of refrigerator or freezer and also the necessary material for the sales department of thermal insulated material. Aluminum tape is widely used in refrigerator, air conditioning, automobile, petrochemical, bridge, hotels and so on. Products description With purity of more than 99.95%, aluminum tape can eliminate electromagnetic interference (EMI), isolate electromagnetic wave to human body harm and unnecessary voltage or current that may influence its function. In addition, Electrostatic discharge after the ground has a good effect . Since its material is polyesters fiber, it is not easy to be damaged or cracked after multi using or bending. Due to its strong adhesion and good conductivity, it can easily fit in the wire winding and be cut according to customer requirements.
Q:Aluminium daily maintenance need to pay attention to what matters?
3.aluminum storage environment should be dry, bright, well-ventilated, non-corrosive climate; 4.aluminum in the handling process must be handled with care to prevent the bump caused by surface scratches, impact surface aesthetics;
Q:Where to buy aluminum tape?

Q:How is the multilayer-stacked aluminum waterproof roll?
Aluminum foil SBS waterproof roll is more effective when multilayer stacked. Aluminum foil SBS waterproof roll combines with SBS rubber modified asphalt with enhanced waterproof abilities through advanced manufacturing machines to produce a series of world-led SBS waterproof film, providing prolonged and reliable protection of architecture and civil engineering.
Q:Why is the aluminum foil in the lithium ion battery eroded ?
During reverse charging, capacitance works as primary cell with two other power supply shorted. This means aluminum as the negative pole will react with the electrolyte, thus being eroded. Aluminum foil can not work as the negative pole, for Li and Al will alloy with each other at low voltage. The hard oxidation film covering the surface of the aluminum product will prevent itself from further oxidizing. On the contrary, oxygen and water can still react with Iron through the rust. Therefore, aluminum is more active than Iron, but it has better anti-corrosion abilities.
Q:It is an alloy of aluminum foil?
Or thickness after rolling to form a sheet of aluminum in aluminum foil is 0.2mm or less. Aluminum is added to the aluminum other metals or non-metallic material, so that the metal strength.

Q:What causes the velocity effect of the aluminum foil?
During the aluminum foil rolling process, with the rise of the thickness of the foil rolling system and thinning phenomenon is known as speed effect. For speed effect mechanism has yet to be explained in-depth research, the cause is generally believed that the speed of effect the following three aspects:
Q:What refers to the mechanical properties of aluminum foil?
Mechanical properties mainly refers to the tensile strength of aluminum foil, elongation and Erichsen value. From the use of perspective, I hope these three indicators, the higher the better, but on the material itself, these three indicators and mutually contradictory, that is, when the tensile strength of the aluminum foil is relatively high elongation index will decline; and when improving the elongation of the aluminum foil, it will cause a decline in tensile strength.
Q:Does the aluminum has good thermal insulation
The theory of aluminium foil thermal insulation is reflecting the light. I suggest that you can use the professional thermal insulation and temperature preservation material(phenolic foam board,rock wool,EPSXPS.ect.) and choose the right material according to the requirements.
