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.
It's 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.

It'sthicker 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.

Aluminiumhas 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 alloys with a wide range of properties are used in engineering structures. Alloy systems are classified by a number system (ANSI) or by names indicating their main alloying constituents (DIN and ISO).

The strength and durability of aluminium alloys vary widely, not only as a result of the components of the specific alloy, but also as a result of heat treatments and manufacturing processes. A lack of knowledge of these aspects has from time to time led to improperly designed structures and gained aluminium a bad reputation.

One important structural limitation of aluminium alloys is their fatigue strength. Unlike steels, aluminium alloys have no well-defined fatigue limit, meaning that fatigue failure eventually occurs, under even very small cyclic loadings. This implies that engineers must assess these loads and design for a fixed life rather than an infinite life.

Another important property of aluminium alloys is their sensitivity to heat. Workshop procedures involving heating are complicated by the fact that aluminium, unlike steel, melts without first glowing red. Forming operations where a blow torch is used therefore require some expertise, since no visual signs reveal how close the material is to melting. Aluminium alloys, like all structural alloys, also are subject to internal stresses following heating operations such as welding and casting. The problem with aluminium alloys in this regard is their low melting point, which make them more susceptible to distortions from thermally induced stress relief. Controlled stress relief can be done during manufacturing by heat-treating the parts in an oven, followed by gradual cooling—in effect annealing the stresses.

The low melting point of aluminium alloys has not precluded their use in rocketry; even for use in constructing combustion chambers where gases can reach 3500 K. The Agena upper stage engine used a regeneratively cooled aluminium design for some parts of the nozzle, including the thermally critical throat region.

Another alloy of some value is aluminium bronze (Cu-Al alloy).

Q:a chunk of aluminum is at 220degees C is thrown into water that is initially 50degrees C?
(A) Let the aluminum is of m kg, than :- =Q(gain) by water = Q(loss) by aluminum =m x s(water) x delta t*C = m x s(aluminum) x delta t*C =50 x 4187 x (100 - 50) = m x 897 x (220 - 100) =m = 97.25 kg (B) Let the amount of water boiled off is m kg =Q(loss) by aluminum = Qwater(50*C to 100*C) + Q100*C(water to vapor) =500 x 10^-3 x 897 x (220 - 100) = 50 x 4187 x (100 - 50) + m x 2257 x 10^3 =m x 2257 x 10^3 = -10413680 =No water will be boiled off as the energy provided by aluminum is less than required to raise the temperature of water to 100*C.
Q:Aluminum foil burns on an alcohol lamp flame but melts, but does not drip. Why?
The three aluminium oxide two is an ionic compound with the properties of atomic crystals.
Q:What need to use aluminum foil?
1.Flexible package. Flexible package is a bag container made from composite packaging material. It is the ideal packaging material of modern commercial which is not only has functions of moisture-proof and fresh-keeping but also can be printed on many patterns and words. With improvement of people’s live standard, there is still a great space for the development of aluminum foil for flexible package. 2.Medicine foil. Aluminum foil for medicine package mainly includes the easy open bottle cap of water aqua and injection as well as medical PTP aluminum foil. Since PTP aluminum foil is moisture-proof, convenient to carry, safe and health, it is widely applicable to the international medicine industry. 3.Composite aluminum foil for automobile.
Q:Is aluminum foil harmful to the human body?
barbecueSome foods (such as sweet potato, Enoki mushroom etc.) must be wrapped with aluminum foil to avoid burning, burning. With foil wrapped to cook seafood, Enoki mushroom, can retain the flavor. Electric hairSome hair stylists wrap their hair in foil paper to heat their hair, which gives better heat transfer. Improper use of aluminum foil leads to problems such as burns and poor hair quality. oil absorptionTurn the foil into a ball and open it to absorb the oil in the soup. The principle is the process of crumpled aluminum foil, the foil surface tension amplification. chemical reactionAluminum foil, like aluminum cans and aluminum pots, reacts with acids (usually organic acids), while the salts produced by aluminum and organic acids react with acid to form aluminium chloride (AlCl3). Acquisition and manufactureIs the use of aluminum foil rolling press by aluminum block out, and then cut into required length, width, and then roll up, packaging and selling. Ordinary aluminum foil and foil trays can be purchased at supermarkets, department stores and home stores, while industrial aluminium foil can be purchased at hardware stores and industrial materials companies. FunThere are some organized criminals had tried to use aluminum foil bag to package the stolen items, the intention of how had anti-theft machines, but eventually was arrested by the police. SeePlastic wrap - the same as aluminum foil - is a common tool in kitchen cooking
Q:If aluminium is mixed with another metal can it still be a superconductor?
Aluminum by itself is very weak superconductor. If I recall it correctly, its critical temperature is 150 mK. Usually alloys of two or more superconductors are better superconductors than each of the components. Aluminum will probably improve as semiconductor a great deal if something like Sn is mixed in.
Q:What are the types of aluminum tape?
There are two types: specifications (0.05 mm to 0.08 mm) and width (48 mm, 58 mm). Customization for other specifications are available. The length of each volume ranges from 20 to 30. The aluminum foil is single-sided conductive single-sided conductive aluminum foil with the thickness of 10-40! It is also the necessary material for the sales department of thermal insulated material. Aluminum tape is widely used in refrigerator, air conditioning, automobile, petrochemical, bridge, hotels and so on.

Aluminum foil sealing machine packaging systems in the diagnosis and exclusion of the production process control and detection, fault will achieve full automation.
Q:What will happen when aluminum foil mirror is folded in half?
Aluminum foil is rolled aluminum sheets, similar to rolled aluminum foil sheets. As aluminum is soft and ductile, rolled aluminum sheets can be made into aluminum foil by pasting up on the offset paper using substances as sodium silicate. It can also be used for printing. As aluminum itself tarnishes easily with oxidization, friction and touches, it will not be used as covers of books and magazines that usually preserves long.
Q:The difference between pure aluminium foil bags and aluminium plated bags
Aluminum foil bags are divided into pure aluminum bags and aluminized bags, then how to distinguish between aluminum bags and pure aluminum bags in daily life? How many points are summarized?:First, from the material, pure aluminum bags are pure aluminum, high purity, is a soft material; aluminum plated bag mixed with composite materials, is brittle materials.Two, in terms of cost, the price of pure aluminum bags is higher than that of aluminized ones.Three, from the performance point of view, pure aluminum bags moistureproof, cooling effect better than aluminum bag, pure aluminum bag completely avoid light, aluminized bag is shading effect.Four, from the use, the pure aluminum bag is more suitable for vacuum pumping, such as food, meat and other products, while the aluminum plated bag suitable for tea, powder, electronic and other pieces.Five, the inside of the bag facing the light or sunlight, can see through the bag of light is plated aluminum foil, invisible is pure aluminum foil
Q:Aluminum Lab Question?
You have to start with the mass of your aluminum foil so weigh it out, let's call it m. Then find the molecular weight in g/mol from the periodic table, we'll call this MW. Next, calculate how many mols of Al are in your foil: # mols = m / MW Then calculate the number of atoms using Avogadro's Number. # atoms = # mols * Avogadro's Number Finally, divide the # atoms by the population of the world to see how many atoms each person could get from your sample. -trickshottim
