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%

Q:Which kind of machine can produce aluminium tinfoil?
There are special machines with different exteriors and diferent names, which can called as tinfoil container punch.
Q:Does the aluminum foil bag prevent x-ray
The aluminum foil bag can prevent the X-ray.The common indusrial (LED,mask packaging,audio card,food packaging,ect.,the kinds of aluminum foil bag have the function of anti-static and radiation.The common aluminum bag can't prevent the static and radiation,only the special aluminum foil bag can prevent the X-ray)doesn't have such function.The common aluminum bag and PCB board,like the package of tea leaves,can't prevent static and radiation. there are many kinds of aluminum bag.
Q:When baking, what is the difference between aluminum foil and oil on paper?
The role of aluminum foil is heat and fast, even heat, so that the food will not be scorched, can prevent food grilled dirty oil tank at the same time, with aluminum foil wrapped food can be lost by reducing food and nutrition, water loss. So often when things oven with aluminum foil. But remember, the general will add lemon juice to enhance the flavor when baked, but citric acid will react with these metals, carcinogenic at high temperatures. So, you can add lemon juice after baking to eat.
Q:Is there any way to prevent corrosion oxide coated aluminum coil?
Although color coated aluminum coil is widely used, but many companies realize such a problem, a long time will be pre-painted aluminum coil corrosion and oxidation, to solve this problem, what's a few suggestions may help you.
Q:Does the aluminium paper can be used in the micro wave oven?
Yes. Any kinds of aluminium foil can be used in the micro wave oven.The aluminium foil used in the micro wave oven is selled in the supermarket! Control the temperature! The food should be heated balancedly and prevent nutrients loss.I usually use the aliminium foil when cooking the beer fish. Aluminium foil:high temperature cooking aluminium foil、low temperature aluminium foil,ect. The aluminium foil wrapped food should be put into the oven for heating. The use should be avoided if the aluminium foil have the spark when contact to the interior wall of the oven.
Q:Why use aluminum foil packaging of cigarettes?
Eighties, as the inner liner of cigarette aluminum foil and aluminum foil rolling main Metallized, now, composite aluminum foil material has become a development potential, which has light, high barrier and gas, water corrosion resistance, when the temperature changes rapidly, without any material deformation.
Q:What are the advantages of aluminum foil?
Aluminum foil material is soft metal film, the main advantages of which are as follows: 1.It is moisture-proof, air sealing, light shading, wear resistant, fragnance-holding, non-toxic and tasteless; 2.It has a silvery luster and is easy to print all kinds of beautiful patterns of all colors; 3. After aluminum foil composited with plastic and paper, it integrates shielding of the aluminum foil, strength of paper and thermal insulation of plastic, and further improves the shielding function of aluminum foil tape as packing material from moisture, air, ultroviolet rays and bacterial, which has greatly expanded the application market of aluminum foil.
Q:Overview of aluminum foil
Q:What are the advantages of decorative aluminum foil?
Decorative foil insulation, sound insulation, fire protection and easy to clean, etc., but the appearance of luxury, easy processing, construction and installation speed. At present China's construction, home improvement industry has formed a decorative foil application boom.
Q:What are the advantages of a decorative foil?
Quality decorative foil in China's construction industry application from the beginning of the 1990s, with the rapid development of China's construction and decoration industry and real estate, new building decoration materials continue to emerge, in which a large number of applications are high-quality decorative foil, aluminum foil is its the main processing materials. According to the survey, the rapid development of high-quality decorative foil, huge market potential.
