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:Does the ID card placed in the aluminum foil packing bag protect against demagnetization?
The foil is not anti degaussing function, I suggest you go to the Public Security Bureau accreditation department or the bank and other places, with special anti degaussing small plastic bags. Thanks for taking it!
Q:What can an aluminum foil bag hold?
(2) food packaging: milk, rice, meat, fish, aquatic products, meat, Roasted Duck, Roasted Chicken, roast pork, frozen food, ham, bacon, sausage, cooked meat, pickled vegetables, bean paste, spices and incense, durability, security flavor, color retention.
Q:Aluminum foil bag, VCI plastic bag,
Shenyang anti rust packaging materials Co., Ltd. (hereinafter referred to as Shenyang rust prevention), through unremitting efforts, for the first time in the country put forward the concept of thixotropic rust preventive oil. Thixotropy is an object (such as paint) by shearing, consistency becomes small, stop shear, consistency and increased or subjected to shear, consistency becomes large, stop shear, properties of consistency and becomes small, the nature of a touch change. One of the remarkable characteristics of rust proof oil is to form the most suitable oil film on the vertical surface through effective methods to reduce the flow of the facade. At present, globally, there are a handful of manufacturers who have mastered the production of thixotropic rust preventive oils. And Shenyang rust prevention technology team eventually developed a thixotropic agent, becoming the only domestic manufacturer of thixotropic agent. Thixotropy rust proof oil general characteristics, the industry's new approach.
Q:Aluminum foil and aluminum foil is not the same
The first really tin foil made of tin foil paper but because is hard, and has a tin taste retained in the food defect, which later decreased after the price of aluminum foil, foil instead of in their daily lives. However, because of the influence of aluminum on the brain, the surface of the existing aluminum foil is coated with aluminum to avoid the release of the metal.

Mainly in order to distinguish between thickness, the international habit of more than 0.2mm thickness of --500mm, 0.2mm below, 200mm width of more than, length of less than 16m aluminum material called aluminum sheet or aluminum sheet; the following is called aluminum foil material
Q:How does aluminum foil bag should be heat-sealed?
If you don't vacuumize bags,heat-sealing machine is ok. Some heat-sealing machines have hand grips, some are pedaled or with belt wheels. Prices vary with different manufacturers. If you want to vacuumize bags, a vacuum machine is ok. After the vacuumizing process, the vacuum machine is directly sealed.
