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%.

Q:Songs about aluminium?
Aluminum, a song by The White Stripes from their 2001 album White Blood Cells Aluminum (album) a music and art project based upon the White Stripes' music; also an album released by that project Aluminum, a song by Barenaked Ladies from their 2003 album Everything to Everyone Aluminum, the title track from an album by the metal group Sundown Aluminium, a song by Damon Albarn
Q:Does the aluminum foil bag prevent x-ray
The aluminum foil bag can prevent the X-ray.The common indusrial (LED,mask packaging,audio card,food packaging,ect.,the kinds of aluminum foil bag have the function of anti-static and radiation.The common aluminum bag can't prevent the static and radiation,only the special aluminum foil bag can prevent the X-ray)doesn't have such function.The common aluminum bag and PCB board,like the package of tea leaves,can't prevent static and radiation. there are many kinds of aluminum bag.
Q:How much is nine thick aluminum foil bag?
The household bags are different in size.I'm a producer here. Contact: the mouse moves to my user name above, stays for 2 seconds, appears the telephone
Q:why do aluminium bikes cost so much?
Also Aluminum to Aluminum or to steel contact in moving parts tend to seize, so there will need to be bushings for any moving areas such as hubs and brakes.
Q:what are the uses for the isotope aluminum-27?
You'll need to learn about the element Aluminum first and then work your way to the Isotope thing.
Q:What is carbon coated aluminum foil?
Original aluminum conductive properties of the metal itself is already good, but for the greater enhance its conductivity, people invented a carbon-coated aluminum foil. Carbon-coated aluminum foil is referring to the conductive graphite and carbon nano-coated tablets, uniform, delicate coated on aluminum foil, aluminum foil once put on such "nano coat", it will be able to collect micro-current of the active substance and greatly reduce negative resistance between the poles, the static conductivity to maximize the performance.
Q:What are the advantages of aluminum foil?
Compositing aluminum foil thermal insulation material uses the latest international technology of rubber and plastic modification and introduces world-leading technology and equipment of permanent aluminum foil composite, which is rubber and plastic compositing thermal insulation material of international advanced level.
Q:What is performance advantages of carbon-coated aluminum foil?
2. To improve the adhesion of the bonding of the active material and current collector, the material is soft, easy to process and reduce manufacturing costs pole piece. Such as: • improve the use of water-based systems and adhesion of the positive electrode material collector; • improve the adhesion of nanometer or submicron cathode material and a collector; • improve the adhesion or other high-capacity lithium titanate anode material and a collector; • Increased pole pieces made of qualified rate, lower pole piece manufacturing costs.
Q:Performance of aluminum foil and how does it insulate heat? Describe it precisely and in detail and better give the source
Aluminum foil is widely used in fields like food, beverage, cigarette, medicine, photographic plate and family daily necessities as packaging material; electrolytic capacitor material; insulation material for building, automobile, ship and house; and decorating metallic yarn, wall paper, all kinds of stationery and printings as well as decoration and trademark of light industrial products for its nice properties. Among all these applications, aluminum foil used as packaging material can maximize its characteristics. Aluminum foil material is soft metal film, which is not only moisture-proof, air sealing, light shading, wear resistant, fragnance-holding, non-toxic and tasteless but also has a silvery luster and is easy to print all kinds of beautiful patterns of all colors, so it is easier to be favored. Especially after aluminum foil composited with plastic and paper, it integrates shielding of the aluminum foil, strength of paper and thermal insulation of plastic, and further improves the shielding function of aluminum foil tape as packing material from moisture, air, ultroviolet rays and bacterial, which has greatly expanded the application market of aluminum foil. The packaged items are perfectly protected because the light, moisture and air are completely insulated by packaging material. Especially the package for some steamed food use a kind of composite aluminum foil material which can ensure the food does not spoil for more than a year. Besides, it is easy to be heated and opened up, which is very popular with customers.
Q:Bought three side sealed aluminum foil bags, how to seal the four sides at home?
If only the seal is not vacuum, you can buy a heat sealing machine, very cheap,If you don't understand, keep asking me, thank you.
