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's the use of aluminum tape?
Aluminum tape uses quality pressure-sensitive adhesives (PSAs) and has various characteristics such as good stickiness, aging resistance. and greatly enhanced heat preservation. Various width and length are available for 0.05mm-0.08mm specifications. Aluminum foil tape with all the seams of the aluminum foil composite paste, the seal and insulation nails puncture wounds repair. Taking aluminum foil as the base material and then coated with acrylic adhesive, aluminum tape is featured by high peel strength, excellent adhesion and oxidation resistance, corrosion resistance and flame resistance. Aluminum foil can be classified as common aluminum tape, conductive aluminum tape, high peel strength aluminum tape, reinforced aluminum tape, clip marine welding aluminum tape, aluminum tape for heater, etc., so the effects are different.
Q:Will aluminum foil boxes change color when exposed to high temperature?
If long steam fumigation, there may be a slight discoloration, but no problem!
Q:Is aluminum foil pure aluminum?
Not really, aluminum foil can be devided into pure aluminum foil and aluminum alloy foil.
Q:What's the aluminum foil?
To put it simply, it is ultra-thin aluminum sheet.
Q:How does aluminum foil bag should be heat-sealed?
Using the sealing machine.
