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:What‘s the highest temperature aluminum foil can withstand?
Aluminum foil is flexible metal film, not only with moisture, air tightness, shading, abrasion resistance, Paul fragrance, non-toxic and tasteless, and other advantages, but also because of its elegant silver-white luster, ease of processing a variety of colors and beautiful patterns patterns, and thus more vulnerable to people of all ages.
Q:How to eliminate static in aliminum foil bag?
Aluminum foil bag can protect electrostatic sensitive components from electrostatic potential hazards to the highest degree. They unique four-layer structure can form an inductive cover to make things in bags isolate from static electric field. Furthermore, the inner layer is made low density polyethylene which can remove the static can avoid static generation inside the bag. This kind of hot sealable bag is translucence , so the good inside can be easily recognized outside and the product bar code can be read. It's mainly used in package of electronic elements and PC board. It can also be used in packaging industry.
Q:What causes the velocity effect of the aluminum foil?
1, the state of friction between the work rolls and the rolled material changes, with the increase of the rolling speed, into the amount of lubricating oil increases, so that the lubrication between the rolls and the rolled material changes. Reduced coefficient of friction, film thickening, followed by thinning the thickness of aluminum foil.
Q:The thickness of aluminum foil bag is 30 silks. Is it thick or thin?
It's very thick since the aluminum used in composite sluminum foil tape is 0.3mm.
Q:How dose air conditioning aluminum foil work?
Although this pair of natural "enemy" in nature exactly the opposite, but they play a role are the same, the purpose is to let in air conditioning condensate buildup hold together or let slip away quickly scattered and fled condensed water penetration into, to prevent condensation water heat exchanger occupy the site of the sheet surface.
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:What's the difference between tin foil and aluminum foil?
Tin foil paper and aluminum foil paper in the supermarket have no difference (You can read the material description). What used for barbecue is aluminum foil which is often called Tin foil paper in the past (People at that time have never seen foreign items and as the aluminum foil is similar to tin foil, so they believe it is tin foil. )
Q:what do aluminum 613 and 615 stand for?size? material or producing craft?
They are just the model numbers, no other meanings.
Q:It is an alloy of aluminum foil?
Or thickness after rolling to form a sheet of aluminum in aluminum foil is 0.2mm or less. Aluminum is added to the aluminum other metals or non-metallic material, so that the metal strength.
Q:What's the characteristics of aluminum shielded twisted-pair?
What's the characteristics of aluminum shielded twisted-pair? Shielded twisted-pair cable is wrapped with aluminum foil to reduce radiation, but it cannot completely eliminate the radiation. Shielded twisted-pair is more expensive because it is more difficult to install compared to UTP (Unshielded Twisted Pair). Similar to coaxial-cable, shielded twisted-pair should be equipped with shielding connector and corresponding installing techniques. But it has higher transmission rate of 155Mbps in 100m, higher than corresponding UTP.
