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.

Aluminium (or aluminum; see spelling differences) is a chemical element in the boron group with symbol Al and atomic number 13. It is a silvery white, soft, ductile metal. Aluminium is the third most abundant element (after oxygen and silicon), and the most abundant metal in the Earth's crust. It makes up about 8% by weight of the Earth's solid surface. Aluminium metal is so chemically reactive that native specimens are rare and limited to extreme reducing environments. Instead, it is found combined in over 270 different minerals.The chief ore of aluminium is bauxite.

Aluminium is remarkable for the metal's low density and for its ability to resist corrosion due to the phenomenon of passivation. Structural components made from aluminium and its alloys are vital to the aerospace industry and are important in other areas of transportation and structural materials. The most useful compounds of aluminium, at least on a weight basis, are the oxides and sulfates.

Despite its prevalence in the environment, no known form of life uses aluminium salts metabolically. In keeping with its pervasiveness, aluminium is well tolerated by plants and animals. Owing to their prevalence, potential beneficial (or otherwise) biological roles of aluminium compounds are of continuing interest.

Q:if you use aluminum foil for a home made pipe, why is the aluminum foil so bad for you?
Aluminum foil is coated with paint and other types of polish and what not so the stuff that is coating it melts and goes into the air so you would probably get bad fumes and get sick, I wouldn't recommend using an aluminum pipe I'd but one if I were you
Q:In case a bright paper is aluminum foil or foil with what method can distinguish and what with aluminum foil.
A layer of bright in cigarette paper are not foil foil, the foil is a call before, because of the high cost of tin actually no one can do it.
Q:What is the advantage of Cast Aluminium Cookware?
forged aluminum concts warmth with out postpone and is usually slightly thicker tan much less costly SS for greater even warmth distribution. Stailess will stay bright and you may use greater abrasive scrubbers while mandatory. no longer all cookware has Al. previous post is possibly refering to laminated cookware. some are Al. clad on the backside and a few like my wifes Kitchenaide form are SS with Al. coated in SS. The thicker the backside the greater even the warmth combating warm spots.
Q:Are carbon arrows that much better than aluminum arrows?
In the long run you will find it is much cheaper to use carbon arrows even though the initial cost of them is higher then aluminum. And don't be frightened by the videos of carbon arrows breaking when shooting them. The odds of lightning striking you would be about the same. In most incidences of arrow breakage when being shot, it was with a heavy draw compound and using carbon arrows that were much too light weight to be shot from a bow that they were not designed to be shot from. People sometimes use the lightest weight carbon arrows they can find to make their bow shoot faster then anyone Else's. Sometimes they pay a price for it.
Q:What are two chemical reactions of aluminum?
2Al + 3H2O → 2Al(OH)3 Aluminum + Steam - heat - exothermic reaction causing aluminum hydroxide. 2Al + 3H2SO4 → Al2(SO4)3 + H2 Aluminum + Sulfuric Acid - exothermic reaction causing Aluminum Sulfate and Hydrogen Gas
Q:Do subs sound better with aluminum or metal cones?
Aluminum is a type of metal, so if I had to guess, the metal ones you are seeing are aluminum as well.
Q:Will you keep the foil in the fridge after opening?
Because of its soft texture and good ductility, it has a silvery luster. If the rolled sheet is made of sodium silicate on the offset paper, the foil can be printed.
Q:What are the differences between the cold aluminum and the plain foil used in packaging in the pharmaceutical industry? How do you distinguish them?
Cold aluminum is cold formed aluminum foil, which is cold rolled. At this time, aluminum foil has a lot of stress.
Q:What measures do you take to avoid absorbing aluminum?
I buy bottles rather than cans. I never refridgerate/store anything in cans. I went to the dentist (yikes) and had my fillings changed from old metal mix to new white?, whatever. I have heard that all autopsies on alzheimer's patients had high amounts of aluminum.
Q:FIBERGLASS BATT vs REFLECTIVE ALUMINUM SHEET?
This has already been answered in great detail. I thought I would be able to add the ventilation. I can add that there is a temperature controlled attic fan. You set it for the temperature you want the fan to come on and it comes on and shuts off above or below the setting. Good job.
