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 is air conditioning aluminum foil?
Furthermore, in order to improve the life of air conditioning, reducing power consumption and improving the quality and increasing the ventilation cooling effect, and have developed a coating heat exchange fins having various functions, typically a corrosion resistant heat transfer sheet, surface hydrophilic properties change heat sink surface hydrophobicity heat exchanger plate and sheet, and mildew self-lubricating heat sinks.
Q:Is aluminum tape toxic?
Aluminum tape is nontoxic. It uses quality pressure-sensitive adhesives (PSAs) and has various characteristics such as good stickiness, aging resistance and enhanced thermal insulation. Aluminum foil tape with all the seams of the aluminum foil composite paste, the seal and insulation nails puncture wounds repair.
Q:How about the effect of aluminum foil thermal insulation roof?
The thermal insulation principle of aluminum foil film is the reflection of light. For better effect of thermal insulation, it is recommended to use professional thermal insulation material such as phenolic foam board, rock wool, EPS, XPS, etc. Suitable material should be chosen to satisfy different practical requirements. aluminum foil can be used in thermal insulation in high-temperature environment by taking advantage of good reflectivity of aluminum face. However, there is still little heat produced by the air convection between the aluminum faces. If absolute thermal insulation is required, multi-layer vacuum aluminum reflective thermal insulation structure can be used.
Q:Does the aluminum foil can be effective in the environment of temperature 430 degree?
It can endure 430℃
Q:How can aluminum foil classification?
First, according to the thickness Differences can be divided according to the thickness of aluminum foil thick foil, single zero foil and double zero foil. 1. Foil thickness: 0.1 ~ 0.2mm thick foil. 2. The single zero foil: thickness of 0.01mm and less than 0.1mm / foil. 3. The double zero foil: a so-called double zero foil after its thickness is in mm unit of measure of the decimal point two zero foil, usually aluminum foil of a thickness of less than 0.01, namely 0.005 ~ 0.009mm aluminum foil.
Q:Does Aluminum foil glass fabric air duct need thermal insulation?
Sox duct features large air flow and evenly blowing-in; Anti condensation; It is easy to maintain and environmentally friendly; It is light and easy to install; It is highly cost effective. Recently it has been used in a wide range of fields, especially the supermarket industry that develop rapidly.
Q:What is 1235 aluminum foil
Aluminum foil is the thin aluminum sheet which is widely used in the package of drug capsule and the milk seal. The 1235 aluminum foil brand number is the model number.
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:Is aluminum foil paper heat-proof?
It is easier to conduct heat than insulate heat.
Q:What's the material of aluminum foil roller
The aluminum roller the roller plant and the roller machine take the advantage of the pressure produced by the change of temperature.
