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:Which is better, tin foil anti-moisture pad and aluminum foil anti-moisture pad?
Aluminum foil anti-moisture pad is more stable and causes no harm. Tin and aluminum are widely used by us and years have seen no security incidents. But tin is unstable at low temperatures, turning into powders. Aluminum foil moisture proof pad is EVA processed. It is user friendly and cost effective. The shortcoming is easily damaged.
Q:What are the advantages of aluminum foil?
Compositing aluminum foil thermal insulation material uses the latest international technology of rubber and plastic modification and introduces world-leading technology and equipment of permanent aluminum foil composite, which is rubber and plastic compositing thermal insulation material of international advanced level.
Q:What's the meaning of 13*18 4 of aluminum bag
The width should be shorten 1-2CM,the self-styled self-reliance aluminum foil bag should be 13cm*18cm+4cm.the calculation of length should be shorten 2,including the pressing seal.
Q:What is called soft canned?
Insufficient retort: The volume of the bag is limited, capacity is generally 50 ~ 1000g. Loading slow, low production efficiency. High cost, applicability broad enough.
Q:Can aluminum foil be put in microwave oven?
Aluminum foil can be used in the microwave oven. Since chicken wing tip, chicken breast or fish head, fishtail or cake edges are easy to overcook, wrapping them with aluminum foil can be helpful to evenly cooking. Tips for microwave oven: 1. Use aluminum foil paper. Since chicken wing tip, chicken breast or fish head, fishtail or cake edges are easy to overcook, wrapping them with aluminum foil can be helpful to evenly cooking. 2. Use vessel cover or fresh-keeping film cover. When cooking or stewing food, to keep the original flavor, prevent evaporation and speed up cooking, vessel cover or fresh-keeping film cover are recommended to use. 3. Use tissue or napkin. Putting a tissue under the food such as baked bread, biscuit, chicken/pork pieces with bread crumbs can keep the food dry and crisp. Covering or wrapping the steamed bun or cakes with wet gauze or tissue can prevent evaporation. 4. Stirring the soup to reset the sliced meat, beefsteak and so on can help improve the cooking. 5. Lay the food aside or add seasoning after heating (for example, add emulsified oil or sauce and then sprinkle chili powder or bread crumbs )can achieve an effect that cooking does not achieve.
Q:What need to use aluminum foil?
1.Flexible package. Flexible package is a bag container made from composite packaging material. It is the ideal packaging material of modern commercial which is not only has functions of moisture-proof and fresh-keeping but also can be printed on many patterns and words. With improvement of people’s live standard, there is still a great space for the development of aluminum foil for flexible package. 2.Medicine foil. Aluminum foil for medicine package mainly includes the easy open bottle cap of water aqua and injection as well as medical PTP aluminum foil. Since PTP aluminum foil is moisture-proof, convenient to carry, safe and health, it is widely applicable to the international medicine industry. 3.Composite aluminum foil for automobile.

Q:What's the characteristics of aluminum shielded twisted-pair?
There are four types of twisted-pair cable shielding: 1. Wrapping four pairs of wires only with aluminum foil; 2. Wrapping each pair of wires with aluminum foil and no metal net outside the four pairs. Since there is only one layer of shielding in outer sheath, it is called single shielded twisted-pair cable. 3. Wrapping four pairs of wires with aluminum foil and meal net; 4. Wrapping each pair of wires with aluminum foil and then add a metal net outside the four pairs. Since each wire has a layer of shielding and there is one layer of shielding in outer sheath, it is called double shielded twisted-pair cable.
