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:What are chemical and physical properties of Aluminum, Iron, and Chromium ?
Chemical Properties Of Aluminum
Q:What exactly is the bright and foggy surface of the foil in the barbecue?
Before that with foil matte is food placed on the original side bright bright surface will better reflect heat so at the barbecue, will light up, can be reflected to the heat on food will repeat if the fog reflecting surface roughness of gas kinetic energy loss is bigger,
Q:How to use aluminum foil sunshade board?
That's easy. When you open it, just turn the aluminum foil out of the way. Suck the sucker onto the car glass. This product is used in the car!
Q:What's the difference between singled-sided conductive aluminum tape and double-sided conductive aluminum tape?
The differences between single-sided aluminum tape and double-sided aluminum tap: Single-sided aluminum tape only has one side of conductive aluminum foil while the double-sided aluminum tape has two sides. Single-sided conductive aluminum tape. Bridge erecting machine is composed of single main-beam, landing leg, hanging beam trolley, ambulatory and transverse gadget, electronic control system, etc. Double-sided conductive aluminum tape. Main beams often adopt triangle truss style, Bailey truss style or box structure.
Q:how much aluminum can be produced?
4Al + 3O2 === 2Al2O3 Aluminum and oxygen are of their elemental states, they usually react to type a compound. So it is a redox reaction. Mentioned a different way, the oxidation numbers of aluminum and oxygen start at zero and alter to +3 for aluminum and -2 for oxygen, and that is oxidation and reduction.
Q:Aluminum Outlet/Receptacle?
Aluminum outlets don't exist. Aluminum conducts electricity so it wouldn't work. Did you mean aluminum outlet box? You can buy those about anywhere that sells electrical supplies. Buy a grey one and paint it black.
Q:How to use the bright surface and non-bright surface when having a barbeque.
The non-bright surface is heat-resistant and the bright surface may release metal toxins yc1962……
Q:What's the function of aluminum foil
It can be used to wrap the food to cook(by pot), like barbeque.
Q:is it a bad idea to use aluminum foil wen it comes to store food?
As everyone says, you can use it to wrap something dry or fatty, as the aluminum will not dissolve or corrode. If the food is moist and/or acidic, don't use aluminum foil. You can use it to cover cups of pudding in the fridge, since it does not touch the food. But it is generally not air-tight. You can use plastic film to wrap anything that will dry out, such as cheese or smoked fish. If you are nervous about anything being in contact with your food, wrap it in a bit of wax paper first and then the plastic film. That is pretty much the way your deli wraps things.
Q:The network structure of aluminum foil and separate line together with differences
This structure can prevent the wire broken insulation, and can be fixed easily through the internal structure, test.
