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.

Q:What is the effect of aluminum on electronics?
Placing aluminum near almost any electrical device should have no effect. Placing aluminum ON an electrical device (not on the plastic housing etc.) may cause problems (short circuits.) Really, you shouldn't worry. Many electronic devices are housed in aluminum enclosures (Everything from DVD players to computers are usually housed in aluminum structures.)
Q:What is the international standard of aluminum foil tape ?
Single lead, a kind of thermal insulation material, is a must buy to the distribution department. It is widely used in refrigerator, air-conditioner, automobile, petrifaction, hotel and electronic industry.
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:Aluminum foil composite film which good quality?
Suzhou Heng Tuo packaging materials Co., Ltd. is located in Suzhou Industrial Park, is a research and development, production and sales of plastic packaging materials professional company. The company has advanced production technology, with strong product development capabilities and production technology, currently has wide extrusion machine, dry compound machine, automatic bag making machine, high-speed slitting machine and other sets of advanced production equipment and testing instruments.
Q:What’s the advantages of aluminum foil thermal insulation materials. There are as follows:
Aluminum foil thermal insulation material is an advanced rubber composite product. It uses the latest rubber modified technology in the world and aluminum foil composite technology and equipment ensuring permanent usage
Q:The difference between pure aluminum foil bag and aluminized foil bag
The pure aluminum bag is made by the aluminum foil, the aluminized foil bag is made by the aluminized film.The pure aluminum metal can be closed by hot-press.
Q:were can i buy paint for an aluminum boat?
dtm is the way to go it lasts just as long as the expensive stuff that you can buy at any marine store and you can get it at your local hardware store dtm=direct to metal. save your money for more expensive parts you may need in the future.
Q:Is the aluminum-foil paper flame retardant?
The aluminum-foil paper is a bond paper made by aluminum foil backing paper and aluminum foil.The main material is aluminum.The pure oxygen of aluminum is 550 degree. When burning aluminum, an oxidation film will form in the air,making the burning become difficult.
Q:Why aluminum foil should be used in capacitor material of distributors?
The normal metal capacitor, especially CBB21/,DV/, impulse current of its turn-off voltage is very high. The capacitor material of distributors, if the distributors of ignitor can't bear such high impulse current. Using CBB28 or CBB8,in which the capacitor can bear a higher impulse current.The ratio of DT is higher.
Q:Which is stronger, lexan or aluminum?
Aluminum alloy is much stronger. I didn't know about Lexan but a google search for lexan mechanical properties shows tensile strength of 9000 psi. You can easily get 6061-T6 aluminum at 42,000 psi tensile strength. It's probably the most common aluminum alloy, more common than pure aluminum. Probably more expensive than Lexan. Lexan is 40% lighter. Also of course you can see through Lexan. The actual working strength depends a little on what you are doing, because bending depends a lot on thickness. If you are stopping bullets, .4 inches of aluminum is probably not as good as 1 inch of Lexan.
