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. We manufacture in compliance with the main international specifications, and tighter tolerances or custom tempers are available upon request. We offer various surface conditions, custom finishes (painting, anodizing, embossing), special processing, and multiple packaging options to meet our customer's unique requirements. The following is a summary of our capabilities.

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.

Hengfeng aluminum foil corrosion-resistant thermal insulated tile, thermal insulated tile, composite aluminum foil tile, aluminum plastic tile, fireproof energy-saving tile. The price is about 38 yuan. 2. Bnagte fireproof aluminum foil cloth, roof color steel tile, thermal insulated sun-proof thermal insulated film/board. The price is about 4 yuan. 3. Nano environmental and energy-saving tile, aluminum foil, thermal insulated soundproof and fireproof tile used in chemical plant, pig farm, chicken farm. The price is about 32 yuan. The above prices are from Internet and for your reference only. Prices may vary according to specific circumstances.
Q:How about the specifications and prices of aluminum foil thermal insulated hose?
Aluminum foil hose is made by winding aluminum foil glass fiber cloth and steel wool on both sides. It has several types including square hose, circular hose, composite hose and thermal-insulated hose. Since it has good fire resistance and flexibility, it can be used in the ventilation o high-rise buildings. Aluminum foil thermal-insulated hose is made by stuffing glass wool between the two layers of aluminum foil on both sides to preserve the internal heat. Coated with aluminum foil Mylar, aluminum foil hose is internally supported by spiral steel wires. By bonding the aluminum foil Mylar on the steel wires and reinforcing the adhesion and tension in the basement layer, aluminum foil hose is characterized by good resilience, fire resistance and safety, thus it is easy for construction. aluminum foil hose is used in dust absorption and air exhaustion such as air exhaustion of public baths.
Q:How many does one square meter of steel structure of the aluminum foil glass wool lap blanket cost?
It depends on thickness and unit-weight of glass wool and the type of aluminum.
Q:What’s the use of aluminum foil glass wool felt ?
We choose the glass cotton lap felt from three aspects: Size: the thickness can be 50mm, 75mm, 80mm…200mm. Glass cotton felt is a product for large-area coverage. It has such properties as preserving heat, reducing shock and absorbing sound especially at low and medium frequency. It can reduce the noise and improve the working environment.
Q:What are the differences among aluminum foil,pet,and hologaram paper
The methods to distinguish the pureness of aluminum foil paper:The color of 99.9% pure aluminum and hologram papershould be processed to the color like aluminium oxide.
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:Who knows the price of 3m conductive aluminum foil tape?
Q:Aluminum foil paper and tin foil paper
The difference between aluminum foil and tin foil, which are mainly used to wrap cigarette, is their thickness and control of high temperature resistance! “Tin foil” and “aluminum foil” are produced respectively by metal tin and aluminum through calendaring. Aluminum foil paper mainly use offset printing, for example, the disposable meal box on the plane which is made from aluminum foil and can be heated in micro-oven, some fried food and aluminum foil for hairdressing like so called tin foil perm. Besides, aluminum foil is applicable to many fields like packaging, printing, medicine, electronic, food, and building.
Q:How to classify aluminum foil according to shape?
Aluminum foil can be divided according to the shape of a roll of aluminum foil and a sheet of aluminum foil. Aluminum foil deep processing wool was rolled supply most, only a few handicraft packaging occasions with a sheet of aluminum foil. Aluminum foil can be divided according to the state of a hard foil, semi-rigid foil and soft foil.
