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:Does the waterproof effect good if the SBS roll of aluminum foil used in conjunction
Generally speaking, the effect of SBS waterproof roll used in conjuction is better than a single laye.rwhen having the construction, the roll is playing the role of light-reflecting and heat-insulation.when the roll is used in conjuction, the second time should use the PE.
Q:How aluminum foil is uesd in food packaging?
Depending on the purpose of the use of flexible packaging. Flexible packaging not only with moisture, fresh effect, but a variety of printable patterns and text, is an ideal material for modern commercial packaging. With the improvement of people's living standards, as well as flexible packaging foil much room for development.
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:What is the value of scrap aluminum recycling?
Waste aluminum foil wide range of sources, mainly from cigarettes, food and pharmaceutical packaging, the main ingredient is aluminum, with high economic and social value of recycling. The experimental study, the use of waste aluminum foil PAC optimal conditions and scope, has a certain practical significance in improving resource utilization, environmental protection and other aspects.
Q:What specification does air hose of aluminum foil have?
The specification and dimension of aluminum foil air hose: 1.2Ф- 16Ф. 2. thickness of pipe: 0.03mm. 3. temperature: -30℃+150℃ 4. steel wire: 0.8-1.4mm 5.flow velocity: aluminum foil fiexible air hose 28M/S. Good weather fastness, suitable for damp place and moderate cost. Galvanized steel pipe is fireproofing and easy to make. The inwall of air hose is smooth and with good air tightness resistance and bearing strength. The field fabrication of air hose is convenient. It's with high strength, strong ability to resist static pressure and is easy to carry. It won't be damaged after being collided. Generally aluminum foil telescopic air hose is vacuum exhaust, usually used in the bathroom defend bath to exhaust air.
Q:Can aluminum foil paper be put in microwave oven?
Carbon-coated aluminum foil is an technology innovation which conducts surface treatment of conductive substrate of battery by using functional coating. Carbon-coated aluminum foil/ copper foil refers to evenly coat aluminum foil/ copper foil with predispersed nano conductive graphite and carbon coated particles. It has good static conductivity and collects micro current of active material, thus reducing the contact resistance between the positive/negative electrode material and flow concentration, enhancing the adhesion to each other and significantly improving the battery performance. The coating can be divided into water-borne coating (water system) and oil-borne coating (organic solvent system).
Q:What's the minimum length of aluminum foil a roll?
A roll of aluminum foil is 12000meters and the aluminizer is 6000meters.
Q:Aluminum foil and fold thickness difference is caused by what?
Difficult to control the thickness difference is a feature of aluminum foil rolling, 3% of the difference between the thick plate production when maybe difficult, but they are enormously difficult in aluminum foil production. The reason is that thin, other trace conditions can be affected, such as temperature, oil, and gas concentration.
Q:which one, aluminum foil or tin does well in heat insultaion and with a lower cost?
There is no distinct difference between them in heat insultation. Aluminum foil is cheaper than tinfoil.
Q:How to do with damage in aluminum foil packing for lithium battery?
1. Generally only the aluminum surface of lithium battery can be damaged. However, its chemical compounds are quite active. Once exposed to air, it may react violently, but it will not explode. 2. It is not recommended to throw it in the garbage in case of contacts with others or reaction with other matters due to its corrosion. 3. It is recommended to wash the battery with ample water. For one thing, instead of elements of heavy metal or heavy toxicity, lithium battery contains many chemical compounds which can be hydrolyzed into salts with lower toxicity or without toxicity. For another thing, because of less amount, throwing it in the sewage has little impact on the environment. 4. You can throw it away because of its little pollution. it is aluminum sheet, copper foil and plastic layer that cannot be dissolved.
