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.

Coal (from the Old English term col, which has meant "mineral of fossilized carbon" since the 13th century)is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers or veins called coal beds or coal seams. The harder forms, such as anthracite coal, can be regarded as metamorphic rock because of later exposure to elevated temperature and pressure. Coal is composed primarily of carbon along with variable quantities of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen.

Throughout history, coal has been used as an energy resource, primarily burned for the production of electricity and/or heat, and is also used for industrial purposes, such as refining metals. A fossil fuel, coal forms when dead plant matter is converted into peat, which in turn is converted into lignite, then sub-bituminous coal, after that bituminous coal, and lastly anthracite. This involves biological and geological processes that take place over a long period. The Energy Information Administration estimates coal reserves at 948×109 short tons (860 Gt).One estimate for resources is 18 000 Gt.

Coal is the largest source of energy for the generation of electricity worldwide, as well as one of the largest worldwide anthropogenic sources of carbon dioxide releases. In 1999, world gross carbon dioxide emissions from coal usage were 8,666 million tonnes of carbon dioxide.In 2011, world gross emissions from coal usage were 14,416 million tonnes.Coal-fired electric power generation emits around 2,000 pounds of carbon dioxide for every megawatt-hour generated, which is almost double the approximately 1100 pounds of carbon dioxide released by a natural gas-fired electric plant per megawatt-hour generated. Because of this higher carbon efficiency of natural gas generation, as the market in the United States has changed to reduce coal and increase natural gas generation, carbon dioxide emissions have fallen. Those measured in the first quarter of 2012 were the lowest of any recorded for the first quarter of any year since 1992.In 2013, the head of the UN climate agency advised that most of the world's coal reserves should be left in the ground to avoid catastrophic global warming.

Coal is extracted from the ground by coal mining, either underground by shaft mining, or at ground level by open pit mining extraction. Since 1983 the world top coal producer has been China.In 2011 China produced 3,520 million tonnes of coal – 49.5% of 7,695 million tonnes world coal production. In 2011 other large producers were United States (993 million tonnes), India (589), European Union (576) and Australia (416).[9] In 2010 the largest exporters were Australia with 328 million tonnes (27.1% of world coal export) and Indonesia with 316 million tonnes (26.1%),while the largest importers were Japan with 207 million tonnes (17.5% of world coal import), China with 195 million tonnes (16.6%) and South Korea with 126 million tonnes (10.7%).

Q:Can aluminum foil be put in microwave oven?
Aluminum foil can be used in the microwave oven. Since chicken wing tip, chicken breast or fish head, fishtail or cake edges are easy to overcook, wrapping them with aluminum foil can be helpful to evenly cooking. Tips for microwave oven: 1. Use aluminum foil paper. Since chicken wing tip, chicken breast or fish head, fishtail or cake edges are easy to overcook, wrapping them with aluminum foil can be helpful to evenly cooking. 2. Use vessel cover or fresh-keeping film cover. When cooking or stewing food, to keep the original flavor, prevent evaporation and speed up cooking, vessel cover or fresh-keeping film cover are recommended to use. 3. Use tissue or napkin. Putting a tissue under the food such as baked bread, biscuit, chicken/pork pieces with bread crumbs can keep the food dry and crisp. Covering or wrapping the steamed bun or cakes with wet gauze or tissue can prevent evaporation. 4. Stirring the soup to reset the sliced meat, beefsteak and so on can help improve the cooking. 5. Lay the food aside or add seasoning after heating (for example, add emulsified oil or sauce and then sprinkle chili powder or bread crumbs )can achieve an effect that cooking does not achieve.
Q:why does the hardness of 2024 aluminum sheet not increase but decrease after thermal treatment?
The hardness of 2024 aluminum sheet will decrease after thermal treatment(solution treatment), and it will increase after aging treatment.

Q:how to process 0.3mm hole on aluminum material?
punching wire-electrode cutting
Q:Which kind of material does aluminum sheet(aluminum oxide) belong to?
it's metal and belongs to hardware
Q:how to separate the aluminum sheet in plastic?
Put them into clean water if both of them won’t react with water, and aluminum sheet will sink into the bottle, then fish up them separately.
Q:If the aluminum coil is 220 kg, 0.3 thick and 500 wide, how much is the coil diameter?
With the outer diameter and inner diameter, you can know the volume. With the density and volume, we can calculate the weight. And with weight, we can know the length.
Q:The specification of thermal insulating aluminum coil
4-0 In general, the chemical engineering products for thermal insulation is 0. According to the International standard, the thickness tolerance is +-5%.02MM. according to industrial standard, it is +-0. The production crafts are embossed and plain sheet.
Q:Why the double-sided self-adhesive foil easily layered and very smelly.
Generally speaking, both sides of double-sided self-adhesive are usually isolating membrance, not aluminum foil. Both sides need to be uncovered to use as pre-installed and inverted adhered. If one layer is aluminum foil, it's one side self-adhesive. If it's smelly, it is must made of inferior raw material with one industrial waste as self-adhesive material. This kind of raw material has strong cancerogenic effects.It's also very smelly in the making process. Campus surrounding plants also die because of the smell. What's more, its waterproof effect is also decreased. You would better not to use it.
Q:What is foil bags vacuum cooking?
High-temperature sterilization of meat due to high heating temperature and excessive shrinkage fibers so that the meat taste better than low-temperature sterilization products, but because of the removal of all bacteria, eliminating internal rot, can significantly extend shelf life.
