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:Does the waterproof effect good if the SBS roll of aluminum foil used in conjunction
Generally speaking, the effect of SBS waterproof roll used in conjuction is better than a single laye.rwhen having the construction, the roll is playing the role of light-reflecting and heat-insulation.when the roll is used in conjuction, the second time should use the PE.
Q:What's the difference between colored aluminum and coated aluminum foil?
According to your description, I suggest you adopt acid pickling process. The basic principle is that aluminum foil will conduct oxidation reaction after being put into the acid to change the color of aluminum foil, which will meet your requirement. The color belongs to aluminum itself not painted by people! This method can get many colors like golden and milky. Different acid ratio will lead to different color.
Q:How to produce aluminized paper?
Q:What are the characteristics of high-quality decorative foil is?
Quality decorative foil insulation, sound insulation, fire protection and easy to clean, etc., but the appearance of pro-China, to facilitate processing, construction and installation speed. At present, construction, home improvement industry has formed a decorative foil application boom.
Q:What temperature needed to keep the aluminium foil spray lacquer having the adhesive force
To judge the adhesive force of oil paint of aluminium paper,we should heat the double paint formulations and the curing agent of the lacquer to 80 degree and 150 degree.
Q:Aluminum corrosion resistance is mainly reflected in what areas?
Third heat-resistant properties, that at a certain temperature, a certain humidity place a long time corrosion sex. The performance is also an important indicator to measure the heat transfer sheet weathering capabilities.
Q:What's the shiny alluminum foil?
Rubber resin ink industry generally adopts two kinds of rubber resin, namely, chlorinated rubber and thermopren. Natural rubber can be considered as shiny alluminum foil. Unmodified epoxy resin can be used as a light cover and aluminum foil coating.The epoxy resin can react with amine or reactive polyamide,organic acid,carbimide,phenol,aldehyde, melamine and formaldehyde resin to generate a soft film.
Q:What is carbon coated aluminum foil?
In fact, we see the "nano" word, no doubt to be sure, coated carbon foil is an advanced breakthrough technology innovation, so easier to save battery power, power loss is smaller, significantly improving the overall performance of the battery .
Q:What defects may causes through the aluminum foil roll?
All the rolls can cause surface damage factors, can be formed on the aluminum foil rolling harm. Because aluminum foil rolling roll surface finish high, slight gloss surface unevenness will affect its status. Periodically clean mill, mill kept clean, to ensure the normal operation of roll clearance, roll change periodically, reasonable grinding, it is to ensure a uniform surface substantially aluminum foil rolling conditions.
Q:It is an alloy of aluminum foil?
Because aluminum is soft, ductile, with silver-white luster, if the sheet after the rolling, sodium silicate and other material mounted in offset paper made of aluminum foil, but also for printing. But the aluminum foil itself is easily oxidized and darkened, friction, touch, etc. will fade, so does not apply to long-term preservation of stamping book cover or the like.
