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:How to use aluminum tape?
Aluminum tape is suitable for all kinds of transformers, mobile phone, computer, PDA, PDP, LED displays, notebook computers, copiers and other electronic products in which electromagnetic shielding is required. Decorative aluminum foil is an aluminum-plastic composite material used for decoration by taking advantage of good colorability and high heat reflectivity of aluminum foil. It is mainly used in building, furniture decoration and part of gift box packaging.
Q:Are high-temperature aluminum foil?
The role of aluminum foil: The first is to prevent food sticking baking sheet; The second is to prevent food tainted dirt; The third is easy to brush the pan; The fourth is when there is some grilled food seasoning, stuffing and other fear dissipated with aluminum foil on the package; The fifth is to prevent moisture loss and keep fresh.
Q:What's the highest temperature resistance of the aluminum foil ?
Aluminum foil is directly pressed by aluminum. Melting point: 660.37, fire point: 550℃. I’m not sure whether it can be installed, but since it is exhaust duct, the temperature may not be too high. It will not be much higher than 100℃ anyway as the boiling point of water is just 100℃.
Q:Aluminum foil bag, VCI plastic bag,
Shenyang anti rust packaging materials Co., Ltd. (hereinafter referred to as Shenyang rust prevention), through unremitting efforts, for the first time in the country put forward the concept of thixotropic rust preventive oil. Thixotropy is an object (such as paint) by shearing, consistency becomes small, stop shear, consistency and increased or subjected to shear, consistency becomes large, stop shear, properties of consistency and becomes small, the nature of a touch change. One of the remarkable characteristics of rust proof oil is to form the most suitable oil film on the vertical surface through effective methods to reduce the flow of the facade. At present, globally, there are a handful of manufacturers who have mastered the production of thixotropic rust preventive oils. And Shenyang rust prevention technology team eventually developed a thixotropic agent, becoming the only domestic manufacturer of thixotropic agent. Thixotropy rust proof oil general characteristics, the industry's new approach.
Q:Find a weld and riveting machine to connect the two roll of aluminum together. the width of aluminum is 40-60cm,because the surface of aluminum has a layer of oxidation film,so...
I am a high voltage professional welder. I can't endure the current surge,even the spot welding. the surface oxidation film can be baked by the cutting knife,or polish by the abrader. no matter how big the welding rod is useless.The aluminum is too thin.
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:Oak barrel aluminum foil liner or well logs
Of course, the log is good, some ingredients in the log can serve as a better direction for the development of wine, and aluminum foil can not.
Q:Compare "foil, wooden ruler, cotton, the best sound effect of what kind of material is nylon rope
The best foil transmission effect, because the metal sound effect is the best
Q:How can the aluminum foil hose be connected with the toilet exhaust fan?
Interface must be more winding a few laps, and after installation, to open the exhaust fan test whether the exhaust is normal, that is complete installation.
Q:Can I use the foil to steam the fish in the microwave?
Do not recommend the use of aluminum foil, this is one kind of metal, the microwave oven heated by microwave, microwave reflection effect of the metal will encounter, cooking, microwave cooking materials can be selected: A, B, C, glass ceramic, plastic film D.
