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 the food grade aluminum-foil paper concretely mean?
Aluminum-foil paper used in barbecue is namely aluminum foil. It can not only be used in barbecue, but also can be used to hold food in service plate. Some jerky's vacuum package is also aluminum foil.
Q:What are good brands of aluminum tape?
There are many brands of aluminum tape. The features vary with manufacturers. We cannot say which is best, but say which is better.
Q:What are the advantages of aluminum foil?
Aluminum foil material is soft metal film, the main advantages of which are as follows: 1.It is moisture-proof, air sealing, light shading, wear resistant, fragnance-holding, non-toxic and tasteless; 2.It has a silvery luster and is easy to print all kinds of beautiful patterns of all colors; 3. After aluminum foil composited with plastic and paper, it integrates shielding of the aluminum foil, strength of paper and thermal insulation of plastic, and further improves the shielding function of aluminum foil tape as packing material from moisture, air, ultroviolet rays and bacterial, which has greatly expanded the application market of aluminum foil.
Q:What is carbon coated aluminum foil?
Original aluminum conductive properties of the metal itself is already good, but for the greater enhance its conductivity, people invented a carbon-coated aluminum foil. Carbon-coated aluminum foil is referring to the conductive graphite and carbon nano-coated tablets, uniform, delicate coated on aluminum foil, aluminum foil once put on such "nano coat", it will be able to collect micro-current of the active substance and greatly reduce negative resistance between the poles, the static conductivity to maximize the performance.
Q:What are the types of aluminum tape?
There are two types: specifications (0.05 mm to 0.08 mm) and width (48 mm, 58 mm). Customization for other specifications are available. The length of each volume ranges from 20 to 30. The aluminum foil is single-sided conductive single-sided conductive aluminum foil with the thickness of 10-40! It is also the necessary material for the sales department of thermal insulated material. Aluminum tape is widely used in refrigerator, air conditioning, automobile, petrochemical, bridge, hotels and so on.
Q:What's the aluminum foil coiled material?
The aluminum foil coiled material is a layer of aluminum. If thinner, it is called aluminum film used for SBS or APP. If thicker, it is called aluminum foil used for self adhesion. Actually it is a layer of aluminum film. Manufacturers can produce according to the requirements of customers.
Q:Can I use dyne pen to test the wetting tension in the appearance of aluminum foil? What's the standard?
What kind of dyne pen imported from America enjoy the highest cost performance? The method can accurately measure the surface tension of the base material, surface wet strength and determine the surface factors of base material. Relative humidity should not exceed the standard since high humidity is easy to aggravate the variability of data.
Q:What’s the use of aluminum foil glass wool felt ?
It can also be used in such industries as central air conditioning, architecture, chemical engineering, light textile, metallurgy, ship, auto mobile and appliance to absorb noise and resist heat. Aluminum foil glass cotton serves to preserve heat, prevent moisture and radiation. It is also nice-looking.
Q:Is aluminum foil exactly aluminum foil paper?
Paper stuck with aluminum film made from aluminum can be moisture-proof.
Q:What are the trends of foil sealing technology?
Future of food packaging equipment will be accompanied by automatic industry trend toward the efficient, versatile, low consumption of food packaging equipment development, so as to realize improve our overall level of food sealing machine equipment.
