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%.


We provide a full range of precision aluminum strip for almost any application. We produce aluminum strip in a wide variety of alloys, including clad composites. Our aluminum strip can be produced in standard dimensions or custom made to your special requirements. We produce both imperial and metric units.

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:Does the ID card placed in the aluminum foil packing bag protect against demagnetization?
The foil is not anti degaussing function, I suggest you go to the Public Security Bureau accreditation department or the bank and other places, with special anti degaussing small plastic bags. Thanks for taking it!
Q:Why is Aluminum so reactive?
aluminum reactive
Q:Which fields need to use aluminum tape?
Aluminum tape is used to joint paste all kinds of aluminum composite material like sealing of puncture site of insulation supporting pin and restoration of damaged area, which is the main raw and auxiliary material of freezer manufacturer and the must-have material of distribution departments for thermal insulation material. The product is widely used in fields like refrigerator, air conditioner, automobile, petrochemical industry, bridge, hotel and electronic industry. Copper foil.
Q:Professional chefs: Does copper-bottom cookware pair better with a stainless or aluminum cooking surface?
The only aluminum cooking surfaces are ANODIZED aluminum, which means the aluminum has had a chemical bath, making it stroner than steel. Calphalon One is an example of this. Stainless cooking surfaces are usually preferred by chefs because a) it is nonreactive with acidic foods like tomato sauce b) nonporous and fairly easy to clean and c) stainless surfaces are lighter than the black anodized aluminum, making it easier to see the fond developing in the bottom of the pan. The pan you received is of the highest quality and the kind used by top chefs all over the world. If you want a curable pan, get a couple cast iron pieces. They are super cheap and perfect heat conductors. A well stocked kitchen has stainless, cast iron, and non stick pieces. The right tool for each job.
Q:Aluminum to copper wiring?
yes pigtailing is the proper term. yes it is the best solution for a bad situation. we have personally pigtailed hundreds of homes and have never had any problems. i would feel comfortable with this
Q:Adhesion of aluminum and glass
Firstly, clean them up and then use bi-component polyurethane structural adhesive to spice them. Make the appearance of fiberglass polished and clean.The appearance of aluminum foil would better be anodized to make it have good tenacity and strength.
Q:As for the use of aluminum foil paper,which side is the front side?which side do we use when using the baking oven?
The non-bright side is used to wrap the food while the bright side is used to spread over the plate.
Q:What are the key features and advantages of the aluminum foil food bags?
5, the production of aluminum foil material into the food bags to pack food non-toxic tasteless, health and safety in line with national health standards Aluminum foil material thickness between 70-180 microns, according to different purposes, the size of packaging products made into different processes, aluminum foil food bags long process trilateral envelope, self-reliance bags, zipper bags, standing zipper different craft bags, bags of yin and yang.
Q:Will 1 gram water or 1 gram aluminum have the biggest increase in temperature upon the addition of 4.184 J?
aluminum if something has a high specific heat, it takes more energy to increase its temperature and vice versa. if you add the same amount of energy to two substances, the one with lower specific heat will have a greater increase in temperature.
Q:How should Aluminium react with Hydrochloric Acid?
It will dissolve like ZINC.
