Aluminum foil

The aluminum foil is a thin sheet of approximately 0.02 mm thickness made up of Aluminum. Because of this thinness and Ductilité of metal, paper is very flexible, which enables him to practically marry all the forms.

Description

In the trade intended for the private individuals, it generally comes in the form from a rectangular sheet rolled up on a Tambour, the whole being in a box equipped with a knife notched on an outside.

Paper generally has a very reflexive side and the other chechmate. The manufactoring process is the cause, because a sheet alone being very easy to tear, they are treated in pair, the common side becoming chechmate by friction.

Consumption

It is sold several thousands of tons of aluminum foil at each year, because it is an inexpensive, changeable product and which is degraded very slowly if it is preserved in its packing of origin.

The great consumption of the aluminum paper is criticized by certain ecologists because of the high cost of extraction of the Bauxite, mainly the great quantity of necessary electricity to break up it. However, paper makes it possible to protect from the food to the room temperature, which would be differently damaged without refrigeration. Several recycled aluminum papers take only approximately 5% of initially necessary energy to produce them.

Uses

Paper is used to pack and protect from the Aliment S, the Cosmétique S and the chemicals. Used such as it is, it is in general used to pack food which will be cooked in a closed enclosure (examples: potatoes with the Furnace, onions with BBQ). If it is not used such as it is, it is bound by Laminage to other materials, such of the plastic in sheet and plain paper. Thus the tetrabrik make it possible to preserve food over one long period. Under these conditions of use, the aluminum foil is used at the same time as barrier with the Lumière (which degrades the fats), with the Odeur S, water (preventing the variations of moisture) and with the Bactérie S.

The aluminum containers are used to cook tarts, pies and other dishes with the furnace. Some are conceived to contain Loan-with-to eat and food with animals.

The aluminum paper, easy to work, is also used at the same time like thermal Isolant , electromagnetic insulator and conducting electric. Its conducting properties of heat make of it an object of choice when it is a question of heating a product without putting it in direct contact with the source of heat, in particular for the consumption of some Drogue S.

Metal aluminum, usually of color money, can take another color by electrolysis. This treatment creates an oxide coating on the surface of the sheet, sleep which accepts metal dyes or salts, according to the process used. Thus one can create a sheet, inexpensive, of color gilded. These sheets, inter alia, are used to pack chocolate. Aluminum foil says extremely thus treated is useful in art, Décoration and Artisanat.

Paper is also used to involve the Chat S. Indeed, they hate at the same time its texture and its noise. By depositing a sheet on the pieces of furniture has to protect, of the people manage to correct the cats.

Certain people believe that paper is able to block the cerebral waves which are used to control the Cerveau X. They thus paper of it the interior of their hat.

Like any other metal, aluminum reacts violently when exposed to the microwaves. Those cause the accumulation of electric charges close to the defects in material. For an aluminum foil, they are generally cracks or lips created following the packing of a food. So sufficient loads accumulate, then spark S appear on the surface of the sheet, which can light a Feu.

People crumple in ball a length of paper and cut it using a scissors. It would seem that the knives are sharpened thus.

History

At the end of the 19th century and at the beginning of the 20th century, tin in sheets was of everyday usage. Thereafter, the aluminum paper replaced it.

Anecdotes

This paper is sometimes called “paper of Plomb”, “paper of tin” or “paper of money”, although it is not consisted of the one of these chemical elements or Alliage. Indeed, lead is toxic in the environmental conditions, whereas tin and the money are notably more expensive to produce.

In North America, it is sometimes called Reynolds Wrap , of the name of the company which introduced it for the first time on the market.
