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.

Q:What's the difference between PET gold card paper and aluminum foil gold card paper film?
Aluminum foil gold card paper is used in base materail(paperboard) 1:It is easy to compare the appearance when you know the making process. Aluminum foil is made by pressing vaporized aluminum into slice and then print or thermoprint. Stick to PET thin film and shake it under ray of light. You will find that it is highly reflective. 2: Burning test: PET belongs to transparent plastic. PET gold card paper and aluminum foil have different appearence and making process. 3.PET gold card paper is printed on base materail(paperboard) previously,however, some printing layer don't have good reflective performance. PET thin film is very bright. When aluminum foil gold card paper burn to a cinder, the remained metal aluminum foil is thermoprinted. PET gold card paper can be burned into cinder totally. Aluminum foil is with metallic lustre.
Q:Is it bad to burn aluminum foil?
No. The aluminum will usually not burn. At a temperature in excess of 1150 degrees, and being exposed to an open flame at the same time, will result in the aluminum burning. On a barbecue, you will only have a few hundred degrees. When aluminum burns, it will naturally produce aluminum dioxide, which is not toxic. You don't have anything to worry about. Aluminum only burns in fine powder form, or when it is melted (exceeding 1150F)
Q:What are the important features and advantages of aluminum foil food packaging bags?
It is non-toxic, tasteless, healthy and safe, and conforms to the national hygienic standardAluminum foil material thickness of 70-180 microns, can according to different uses, the size of the products made in different packaging technology, aluminum foil food packaging bags are as long as the process technology of three side sealing bag, portable bag, zipper bag, self-supporting zipper bag, bag of yin and YangCangzhou hannuo plastic packaging Co. Ltd is a professional design and manufacture of aluminum foil bags, food bags, aluminum foil bags, aluminum foil food packaging bag, vacuum aluminum foil bag, aluminum foil bag, aluminum foil bag stand. Companies adhere to the "mutual benefit, customer service" principle, through your joint cooperation between us, you and I realize the common development of the cause!Hope to adopt!
Q:Does aluminum foil bag have property of X-ray proof?
Lead is the best material of property of X-ray proof.
Q:Why clear plate aluminum metal?
Aluminum alloys in general have good corrosion resistance in certain environments and poor corrosion resistance in other environments. Anodizing is a process option for some Al alloys, used to built up thicker oxide surface layer. By controlling the anodizing process, the layer can be made porous so that it accepts dyes. Therefore, some Al alloys can be coated to almost any color of the rainbow. In electrical connections, Al is not generally used because the oxide layer is an insulator. Consult your friendly neighborhood metallurgist for more details.
Q:Are aluminum foil container poisonous?
Light weight aluminum foil products, the products meet the national food hygiene standards. And recycling convenient, no 'harmful substances in the process, and does not pollute renewable resources. Aluminum lunch boxes for aviation product line more food and retail food cake, update speed consume larger quantities. For a bulk sale. Cake cooking food store and finished food packaging are multiple use foil container. Market wide, wide popularization.
Q:is it a bad idea to use aluminum foil wen it comes to store food?
i store all my food in glass containers. vegetables and fruits do not necessarily need to be stored in closed containers, unless they,ve been cooked. i avoid aluminum foil for most things,as it is unnecessary to use it. covering acidic , cooked foods (chili) with foil will cause the foil to corrode.
Q:Aluminum ????????????
Cooking in aluminum pots has been linked to alzheimers, also mining and smelting it does cause pollution....water, air, and toxicity in the soil.
Q:is prestone coolant good for Aluminum radiator coolant ?
Prestone Radiator Coolant
Q:Why it needs to use the diluted alkalito have an reaction with aluminum foil.
Al first has reaction with the alkali and produces aluminium hydroxide.Then aluminium hydroxide has a reaction with four hydroxyl aluminum acid radical{[Al(OH)3]-},which write as (AlO2). Al first have a racction with H2O producing aluminium hydroxide and then have a reaction with alkali.
