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 the aluminum foil bellows insulated or thermally conductive?
It depends on the intention of using the pipe! Aluminum foil has good thermal conductivity! But he can reflect the heat of radiation! His bellows also have a few points, one is corrugated tubes, heat exchange area much larger than the light pipe, and there is bellows flexibility is better! It is not easy to break in thermal expansion and cold contraction! So this kind of pipe is widely used in the field of heat conduction!
Q:How do the foil? Foil is what to do?
Use:Insulation foil is very good.If the summer is covered with a layer of reflective material as the foil on the roof of the sun can solve problems 60%. The rest is to think about this layer of metal. The reflecting film itself will become very hot and heat will continue to pass to the floor.If this layer of reflective film overhead, between the membrane and floor to retain 150 ~ 200mm of the air flow layer, the effect will be very good.The foil has good smoothness and heat reflection, the protection of the foil, the taste of cigarettes is not affected by external stimuli and stale, the more important is that it is not affected by air and humid environment and taste of tobacco in cigarettes, not bad, make their shelf life longer! There are also insulation, beauty factors in it. So the inside of the cigarette case has platinum paper.Barbecue can also be used when used foil. Wrapped in the outer layer of food, cooked quickly and rich in fragrance, not cold. The restaurant Roast Lamb Leg outside generally have a layer of aluminum foil.
Q:What's the function of aluminum foil glass wool felt?
Glass wool belongs to one category of glass fiber and is a kind of manmade inorganic fiber, using quartz sand, limestone, dolomite and other natural mineral as the main raw material, and chemical raw materials like soda, borax, etc, as auxiliary material. Then in the melt state, it is flung into cotton-like entwined O-fibers with external blow.
Q:What ribbon with aluminum foil label
Hello, with resin ribbon for printing, so... The effect will be good. In general the ribbon will print up.We're here for this
Q:What are the uses of aluminum foil?
Three. Automotive composite foilWith the rapid development of automobile and aluminum rate of China's automobile industry continues to improve, the rapid increase in foil market demand for automotive vehicles, there are two kinds of foil, a composite foil is used for automobile air conditioner, automobile air conditioner China has aluminum, aluminum foil on the annual demand of 15 thousand tons; the other a composite foil for auto radiator, used in the manufacture of automobile radiator, condenser and evaporator, the auto radiator aluminum rate reached 40%, the annual demand of 3 thousand tons.
Q:What are the features and advantages of aluminum foil bags?
Aluminum foil bag features:(1) obstructing air, strong performance, anti oxidation, waterproof and dampproof.(2) strong mechanical performance, high explosion resistance, strong puncture resistance and tear resistance.(3) high temperature (121 DEG C), low temperature (-50 DEG C), good oil resistance and good incense retention.(4) non-toxic, tasteless, in line with food, drug packaging hygiene standards.(5) good heat sealing property, softness and high barrier property.
Q:Used in aluminum foil and foil barbecue that better?
Because many seasonings will add some juice, citric acid or acetic acid, but whether it is vinegar (vinegar or vinegar), are acidic substances, if contact with tinfoil or aluminum foil under high temperature metal release, so that the metal content of food rose. Lin Jieliang believes that the single use of tin foil or aluminum foil, separated by high temperature charcoal, can prevent food from burning caused by carcinogens, is more healthy food, but do not recommend adding seasonings containing acidic substances. He added that the roast meat may be baked with the meat and seafood, and the meat is cooked early, the roast time is shortened, and the food is also healthy. Hongkong Eastern Hospital senior doctor Lu Guorong pointed out that in the past did have kidney disease, due to excessive water containing dialysis effect of bone and brain, but the patient is daily inhaled a lot of aluminum directly from the belly, to the barbecue through inhalation of aluminum components, can be high enough to damage the brain, the more study is needed of forensic science.
Q:How to wash away the oil of aluminum foil products after being pressed?
I suggest that you can use the volatile punching oil since it won't be rudimental.
Q:What's the difference between aluminum foil paper and tin foil paper?
Tin foil paper is a filmed metallic paper coated with something like silver, such as the metallic paper used for cigarette packaging. The color is silver. aluminum foil paper is a metallic paper by bonding the slip sheet of aluminum foil and aluminum foil paste. It is used for food damp proof and packaging. Both can be used for cooking and package.
Q:When baking, what time do you use foil paper and blotting paper?
Oil absorption paper is barbecue paper, barbecue paper is made of wood pulp, double coated with silicone resin composition. It has the characteristics of non stick, waterproof, oil proof, and high heat resistance (230 DEG C). It is suitable for baking, roasting, steaming and freezing food. It can be laid on the oven to avoid direct contact with direct fire. Easy to clean without cleaning.
