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 does aluminum foil tube specifications can be classified?
It's my pleasure to answer your queations. It can be divided into food grade pu and texture silica gel material. Specification of pu steel wire hose: Stainless steel hose manufacturer to reduce production costs and enhance the competitiveness of the hose, they usually use 212 rolled steel to replace 304 stainless steel to process production. Due to the quality of stainless steel pipe's heavy quality, not easy to bend, easy to produce retention, it is not easy to use. So that lighter pu texture that can meet the requirements of food grade is more favored by the customers. Pu texture food grade tube adopts food grade PU texture and high temperature extrusion process, taking stainless steel wire as skeleton. Hose is light, flexible and smooth inside and outside, which can prevent microbes from breeding. The diameter of hose varies from 25 mm to 100 mm, fully meeting the needs of various industries. It can be widely used in food processing, beverage, drinks, fruit juices, edible oil, spices and other industries.
Q:What is the difference between the tin foil and aluminum foil?
Aluminum layer not in direct contact with food. How much metal tin containing a little lead from food hygiene, it is better than aluminum foil.
Q:How about the effect of aluminum foil thermal insulation roof?
Aluminum foil for roof thermal insulation may have a little effect, but it is not durable. It is recommended to use foam glass as thermal insulating material which has better effect.
Q:Why use aluminum foil packaging of cigarettes?
Eighties, as the inner liner of cigarette aluminum foil and aluminum foil rolling main Metallized, now, composite aluminum foil material has become a development potential, which has light, high barrier and gas, water corrosion resistance, when the temperature changes rapidly, without any material deformation.
Q:Which kind of machine can produce aluminium tinfoil?
There are special machines with different exteriors and diferent names, which can called as tinfoil container punch.
Q:Can you tell me how to use aluminum foil grill ?
It’s wrong! Aluminum foil will melt into the food at high temperature. When cooking no bone cooked meat such as sauce beef, stewed pork with brown sauce, spiced dog meat or used for vacuum packaging of chemical raw material, we choose aluminum foil. Tin foil is usually used for grilling. There are several reasons. 1, to prevent the food from sticking to the baking tray 2, to keep the food clean 3, the baking tray is easy to wash4, to keep the seasonings and stuffing together 5,to keep the food fresh.
Q:How to do with damage in aluminum foil packing for lithium battery?
Carbon-coated aluminum foil is an technology innovation which conducts surface treatment of conductive substrate of battery by using functional coating. Carbon-coated aluminum foil/ copper foil refers to evenly coat aluminum foil/ copper foil with predispersed nano conductive graphite and carbon coated particles. It has good static conductivity and collects micro current of active material, thus reducing the contact resistance between the positive/negative electrode material and flow concentration, enhancing the adhesion to each other and significantly improving the battery performance. The coating can be divided into water-borne coating (water system) and oil-borne coating (organic solvent system).
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 difference between the cold rolling and hot rolling.
The aluminum foil has no hot rolling and the original billet isn't cold rolling.
Q:How aluminum foil is uesd in pharmaceutical packaging?
Another important market is the aluminum foil is easy to tear film (SP) production, currently there are more than 10 pieces of such production lines, aluminum demand is 3,000 tons / year. In addition salve packaging plastic composite hose, a liquid, injection two potential market cap is plastic composite packaging consumption of aluminum foil, aluminum foil current total demand of more than 1,000 tons.
