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 specification does air hose of aluminum foil have?
The specification and dimension of aluminum foil air hose: 1.2Ф- 16Ф. 2. thickness of pipe: 0.03mm. 3. temperature: -30℃+150℃ 4. steel wire: 0.8-1.4mm 5.flow velocity: aluminum foil fiexible air hose 28M/S. Good weather fastness, suitable for damp place and moderate cost. Galvanized steel pipe is fireproofing and easy to make. The inwall of air hose is smooth and with good air tightness resistance and bearing strength. The field fabrication of air hose is convenient. It's with high strength, strong ability to resist static pressure and is easy to carry. It won't be damaged after being collided. Generally aluminum foil telescopic air hose is vacuum exhaust, usually used in the bathroom defend bath to exhaust air.
Q:Compare "foil, wooden ruler, cotton, the best sound effect of what kind of material is nylon rope
Record sound propagation in different objects, aluminum foil, wood ruler, cotton thread, nylon rope.
Q:How high can the aluminum foil tape be?
Mainly depends on the thickness of the aluminum foil with adhesive. High temperature tape and fiberglass tape, 200 degrees high temperature can withstand.
Q:Can foil paper be used in microwave ovens?
Aluminum foil can not be used in microwave ovens, although the supermarket has dedicated aluminum foil, but be careful. Because the aluminum foil packaging food into the furnace heating, aluminum foil and the inner wall contact will produce sparks.Microwave produced by microwave oven belongs to radio frequency band, usually around 2500MHz. This band of microwaves has the following features: 1) it can be absorbed by food and water, causing molecules to move violently and produce heat. 2) not absorbed by plastics, ceramics, or glass. 3) the metal conducts electricity under the influence of the electric field of the microwave. The electric field of thick metal can resist the microwave, and the microwave reflected out, so the inner wall of the microwave oven is made of thick metal; if the thick walled metal container in the microwave and metal containers will reflect the microwave so that the food is not heated. But the foil is too thin, so electrical conductivity can cause a catastrophic reaction. The process of conducting a thin metal so rapidly that its temperature rises linearly can cause a fire. At the same time, the tip produced by the heat contraction of the foil causes sparks, which can ignite any combustible material in the microwave oven.
Q:Tin foil and aluminum foil can stop / shielding electromagnetic signals?
Tin foil and aluminum foil blocking / shielding electromagnetic signals, regardless of frequency is M, G, or more, can be shielded.Harmless to the human body, you can rest assured that the use ofThe food sold in the supermarket is very good with foil, so you can try it
Q:Can foil paper be baked by fire?
canAskHave you tried it yourself?Chasing the answerTriedDon't overdo it. It shouldn't be too big
Q:How aseptic packaging aluminum foil bags?
Aluminum foil bag is a major cause of the two pollution products after sterilization, disinfection quality of packaging damage to chemical or physical methods of conventional microwave disinfection than conventional heating disinfection required low temperature, a great impact on the quality of the product will not. The use of microwave technology in soy sauce packaging bags to prevent halogen, can prevent soy sauce due to packaging caused by the two pollution problems, and prolong the shelf life of bagged products. In the case of plastic bag sterilization, mainly for sealed aluminum foil bags.
Q:What is the maximum use temperature of foil? Five
If there is no open flame, that is, an electric oven and the like can be more than 300 degrees, no problem, the aluminum foil in the production process through the annealing process, the temperature is over 400
Q:What's the difference between an anode pouch and an aluminum foil bag?
Of course, the first thing to consider is shading, or how about the limitation of shelf life?
Q:Does the aluminium paper can be used in the micro wave oven?
Yes. Any kinds of aluminium foil can be used in the micro wave oven.The aluminium foil used in the micro wave oven is selled in the supermarket! Control the temperature! The food should be heated balancedly and prevent nutrients loss.I usually use the aliminium foil when cooking the beer fish. Aluminium foil:high temperature cooking aluminium foil、low temperature aluminium foil,ect. The aluminium foil wrapped food should be put into the oven for heating. The use should be avoided if the aluminium foil have the spark when contact to the interior wall of the oven.
