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%.

We provide a full range of precision aluminum strip for almost any application. We produce aluminum strip in a wide variety of alloys, including clad composites. Our aluminum strip can be produced in standard dimensions or custom made to your special requirements. We produce both imperial and metric units. We manufacture in compliance with the main international specifications, and tighter tolerances or custom tempers are available upon request. We offer various surface conditions, custom finishes (painting, anodizing, embossing), special processing, and multiple packaging options to meet our customer's unique requirements. The following is a summary of our capabilities.

Manufactured in compliance with the main international specifications and standards, including:  Aluminum Association, ASTM, EN, and DIN.
We can also manufacture in compliance with other international standards including:ASME, SAE, AMS, AWS, FED, MIL, QQ, ISO, BS, AFNOR, JIS and GOST.

Manufactured in compliance with the main international specifications and standards.
Tighter tolerances are available upon request.

Aluminium alloys with a wide range of properties are used in engineering structures. Alloy systems are classified by a number system (ANSI) or by names indicating their main alloying constituents (DIN and ISO).

The strength and durability of aluminium alloys vary widely, not only as a result of the components of the specific alloy, but also as a result of heat treatments and manufacturing processes. A lack of knowledge of these aspects has from time to time led to improperly designed structures and gained aluminium a bad reputation.

One important structural limitation of aluminium alloys is their fatigue strength. Unlike steels, aluminium alloys have no well-defined fatigue limit, meaning that fatigue failure eventually occurs, under even very small cyclic loadings. This implies that engineers must assess these loads and design for a fixed life rather than an infinite life.

Q:Aluminum foil and aluminum foil is not the same
The first really tin foil made of tin foil paper but because is hard, and has a tin taste retained in the food defect, which later decreased after the price of aluminum foil, foil instead of in their daily lives. However, because of the influence of aluminum on the brain, the surface of the existing aluminum foil is coated with aluminum to avoid the release of the metal.
Q:Why the wall insulation aluminum foil is put in the warm side
Putting in the warm side can save the energy and equal to the temperature preservation ratio: In winter,the temperature preservation aluminium is in the interior side of wall in the north.when the temperature of wall rises, the temperature of room is comfortable and the energy consumption is reducing. If putting in the exterior side of wall, the temperature in the room can be risen only after the wall temperature being rising, and the energy consumption is increasing.
Q:Does it hurt much to work in aluminum foil manufacturing enterprises? Ten
Life is so good...... In the company to work with computer damage, go on the road with air hazards, sleeping at home do not know what when the earthquake came, alas, xinjingziranliang factory has so many employee work, relax is good, what is a good job... :: does not affect the daily life, do not affect family reunion. Support one's family............
Q:Aluminum or cooper 1/0 thhn wire?
Juan, Although cheaper, aluminum wire is inferior to copper wire. I didn't think you could even use aluminum wire anymore. At any rate, copper wire is certainly a better choice. Good luck.
Q:Can aluminum foil isolate wireless signal?
Aluminum can nearly isolate all wireless signal, but it should be wrapt tightly. The shielding effect is also related to frequency.
Q:Is aluminum really unhealthy for you?

Q:Aluminum foil wrapped chicken wings, microwave oven, you want to poke holes?
No, just a few knives on the chicken wing, because it's so easy to cook
Q:can use aluminum foil to shield the loudspeaker box wire?
Aluminum foil paper is not easy for grounding. If you can connect the aluminum foil with the pre-stage ground wire of power amplifier and connect well, it surely can help.
Q:Aluminum metal and copper chloride experiment?
Aluminum metal is notoriously nonreactive due to a passivating layer of Al2O3. In the presence of chloride ions, the layer dissolves, producing AlCl4^-, and Al metal, which reacts with Cu2+ ions. Cu metal is produced. You may find Cu metal, and Al metal, plus Cu2+, Cl-, Al3+, AlCl4^- ions. The amounts at the end depend on the amounts you start with. Al2O3(s) + 8Cl- + 3HOH -- 2AlCl4^- + 6OH- 2Al(s) + 3Cu2+ -- 2Al3+ + 3Cu(s) ..... Cl- is a spectator ion
Q:A piece of aluminum foil is available and asked how to measure its thickness, such as the title, thank you
First, the relative value of the foil paper is measured with a scale. It can calculate the area of aluminum foil paper S.
