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:When baking, what is the difference between aluminum foil and oil on paper?
The role of aluminum foil is heat and fast, even heat, so that the food will not be scorched, can prevent food grilled dirty oil tank at the same time, with aluminum foil wrapped food can be lost by reducing food and nutrition, water loss. So often when things oven with aluminum foil. But remember, the general will add lemon juice to enhance the flavor when baked, but citric acid will react with these metals, carcinogenic at high temperatures. So, you can add lemon juice after baking to eat.
Q:How does tin foil act in the aluminum foil rock wool board?
Tin foil in the aluminum foil rock wool board is anti-dust, moisture proof and water proof, for the insulation will be greatly reduced if rock wool absorbs water and with water weighing on it, the rock wool will fall off. Rock wool board made of basalt is an artificial inorganic fiber. It has low heat conductivity. It is light and can not burn. It is inorganic substance and will not turn yellow after absorbing water.
Q:What's the difference between singled-sided conductive aluminum tape and double-sided conductive aluminum tape?
Double-sided conductive aluminum tape: Double-sided conductive aluminum tape. Dual-beam bridge erecting machine is composed of double main beams, landing leg, hanging beam trolley, ambulatory and transverse gadget, electronic control system, etc. Main beams often adopt triangle truss style, Bailey truss style or box structure. Single-sided conductive aluminum tape: Single-sided conductive aluminum tape. Bridge erecting machine is composed of single main-beam, landing leg, hanging beam trolley, ambulatory and transverse gadget, electronic control system, etc. The main beam usually uses box-structured launching nose with light self-weight and high stability which can move up and down, flex front and back, and transverse left and right so as to seat the whole beam and is suitable for straight, skew or curvilinear bridging. Introduction to guide-beam bridge erecting machine: With launching nose as traversing bracket, guide-beam bridge erecting machine uses hauling-up device and
Q:What's the application of double-sided conductive aluminum tape?
1. Aluminum tape is rolled tape by compounding anti-sticking paper and quality aluminum foil which is coated with acrylic adhesive, thus featured by strong adhesion high temperature resistance and aging resistance. It is used for fixing evaporating pipes of refrigeration equipment such as air conditioner, freezer, etc. 2. By padding a layer of glass wool, it is used for thermal insulation of automobile. Generally speaking, it is the less reflective material used in air-conditioning refrigerator.
Q:What's the aluminum sheet and its features?
After been hot-rolled and cold-rolled, aluminum slabs with a thickness of above 0.3mm can be called as aluminium plate or aluminium strip(with a rolled shape); with a thickness of less than 0.3mm can be called as aluminium foil or aluminium foil strip(with a rolled shape). Aluminium foil is usually made of the type 1 or type 2 industrial aluminum. Aluminiym foil has all features of metal aluminium. Heat conduction, gasproof, light insulation and electromagnetic radiation shield are all important features.
Q:Is aluminum foil paper heat-proof?
Yes, it has certain effect on heat insulation because aluminum foil has high radiant reflectance and can reflect some of the solar radiant. However, it’s not practical due to the complicated construction and being easy to be damaged. You can consider using thermal insulation coating which has advantages of simple construction, obvious effect and long service life and doesn’t need special maintenance in latter period.
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:Can aluminum foil insulate heat?
Qualitatively, to ensure shading, not fall, opaque, non-polluting, inexpensive, for advanced cigarettes, candy and other food from moisture and decorative packaging. Extensive use of aluminum foil, for example: Aviation food packaging, general packaging meat, cigarette packaging. Experts according to the different characteristics of the application, it will be divided into more than 20 varieties.
Q:How to prevent foil wrinkling?
Wrinkles: fine foil surface display, vertical or diagonal locally raised, one or several rounded grooves tip, said wrinkles. The main causes of wrinkles: excessive pressure, resulting in uneven deformation during rolling or coiling tension is not enough; inappropriate or rolling roll control pressure is too low; the uneven thickness of the blank, the plate-shaped transverse or bad; lack of precision winding shaft, the sleeve is not round; platen roller pressure properly controlled.
Q:How to test the withstand voltage of capacitance?
Simple test:the two aluminium lead wire rolled up like the electrician high-voltage shaking unit(produce high voltage)and voltmeter and capacitance connected in parallel like revolving unit to the measurement and read the voltmeter. The voltage should be higher than withstand voltage. take the advantage of capacitance aluminium of restoring and measurement.
