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:Is tin foil paper the same as aluminum foil paper?

Q:What is the most important flaw of aluminum foil?
Pinhole major drawback of aluminum foil. Raw material, the upper roll, rolling oil, even to the dust in the air is about the size of 6μm enter the roll gap will cause pinholes, so 6μm foil pinholes is impossible, only the number and size of its evaluation. Due to improved foil rolling conditions, particularly dust and rolling oil effectively filter and convenient roll changing system settings, the number of aluminum foil pinhole increasingly dependent on the metallurgical quality of the raw material and processing defects due to pinholes often defects in materials shedding, it is difficult to find the correspondence between the original defects
Q:What is the difference between the tin foil and aluminum foil?
Metal tin foil rolling production, aluminum foil is rolled production. Aluminum foil can not be rolled out in the past so thin, and when aluminum prices are not cheap, long-term champion in foil and now the rise of the aluminum foil, foil relatively cheap price, most of the aluminum foil packaging has been generally used in food packaging composite film is a combination of a printed layer, a barrier layer of aluminum, heat-sealing layer up.
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:How many applications does aluminum foil have?
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:Is aluminum foil exactly aluminum foil paper?
Paper stuck with aluminum film made from aluminum can be moisture-proof.
Q:Does some one has ever used the aluminium foil paper to keep the house roof from overheat? How about the effect of this method?
if you consider the high compression capability, you can use the honeycomb pannel as your roof. It is environmental friendly, economically,anti- heat and anti-moisture.
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:How to ues aluminum foil container?
Aluminum Foil Container uses: easy to use, easy to shape, health and safety, no smell, no leakage; have good thermal conductivity and uniform heating effect, can be used for oven, oven, steamer and heat sources such as heating directly on the original packaging . Aluminum foil container can withstand temperatures of 240 tall, used in fast food restaurants, take-away match shops, family kitchen, luxury hotels, as well as civil aviation enterprises and packaging food-related service industries.
