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 dying temperature of aluminum-foil paper?
It depends on walking speed.If faster, 180 degree,otherwise 120 degree.
Q:How to produce aluminized paper?
Q:Which fields need to use aluminum tape?
Aluminum tape is used to joint paste all kinds of aluminum composite material like sealing of puncture site of insulation supporting pin and restoration of damaged area, which is the main raw and auxiliary material of freezer manufacturer and the must-have material of distribution departments for thermal insulation material. The product is widely used in fields like refrigerator, air conditioner, automobile, petrochemical industry, bridge, hotel and electronic industry. Copper foil.
Q:Aluminum corrosion resistance is mainly reflected in what areas?
Corrosion resistance is mainly reflected in three aspects: First, alkali resistance, since the surface of lubricating oil required alkaline cleaner to remove the punched sheet after the heat exchanger, the functional requirements of the aluminum foil surface coating must have a certain alkali resistance generally requires soaking in a 20% NaOH solution for 3 minutes without blistering;
Q:Introduction of aluminum foil
Friction. Hiphotos. Aluminum foil is a kind of thermoprinting material made by calendaring aluminum into sheet, Whose thermoprinting effect is similar to that of silver foil.
Q:What's the aluminum foil?
As a kind of decoration, if you make handicraft by yourself, it can broaden ideas, for example, it can serve as filler right hardness when making cross-stitch card pocket. Besides, it can also be used as cooking material, for example, you can wrap the chicken wings with aluminum foil after dipping enough sauce, and then roast the wings after you make sure that the oven can heat metal material.
Q:How to remove words on aluminium foil used in medicine package? Is there any easy way?
Words printed on it is organic matter and can be corroded by concentrated sulfuric acid. Since aluminium plate is protected by oxidation film in its appearance, it's ok to do so. But you should be careful when you operate for plastic plate may also be corroded. Only teflon and high density polyethylene are anti-corrosion, but they are with higher price and therefore won't be used in normal situation.
Q:How does aluminum foil bag should be heat-sealed?
Using the sealing machine.
Q:What are the key features and advantages of the aluminum foil food bags?
5, the production of aluminum foil material into the food bags to pack food non-toxic tasteless, health and safety in line with national health standards Aluminum foil material thickness between 70-180 microns, according to different purposes, the size of packaging products made into different processes, aluminum foil food bags long process trilateral envelope, self-reliance bags, zipper bags, standing zipper different craft bags, bags of yin and yang.
Q:Does the aluminum foil belong to metal material
Yes.
