Aluminum foil: its properties and application

A few words about the production of foil

In fact, the foil is a thin layer of aluminum with a thickness of about 0.2 mm. There are opinions and scientific evidence that the production and use of products containing this metal, contribute to the emergence of cancer. However, despite this, aluminum foil is very popular. As the manufacturers themselves say, it becomes sterile in the manufacturing process and therefore completely harmless.

It was first released in 2004 in Europe. It was then that its sales amounted to about 831,000 tons. Today, about 75% of all aluminum is used for the production of foil for the packaging of all kinds of goods and goods. And approximately 25% is spent on construction( with thermal insulation of houses, for the manufacture of cables and pipes), as well as electronic and aerospace industries.

By the way, in addition to the usual, there is even thinner foil( its thickness is 0.006 mm).

Types of foil

As already mentioned, this material is used in various spheres of life. In this regard, different types are distinguished, for example, in the field of application: aluminum foil technical, food, tape. The former is used to a greater extent in the electrical industry, auto and aircraft building. It is also used as a thermal insulation material for the erection of buildings and structures.

Aluminum construction foil is often used for warming baths, steam rooms, saunas, creates the so-called "thermos" effect. Heat is stored indoors and does not go outside. It is also used for insulation of ventilation systems, pipes, roofs and floors. This material does not create an additional thick layer.

The same group includes food foil, which is used for packaging cosmetic, pharmaceutical, food, tobacco products. The tape is used in the manufacture of wall panels.

The foil is also divided according to the state of the surface into reinforced, corrugated, laminated. The first is made on the basis of a polymer mesh or fiberglass. Provides a slightly rough surface for better adhesion. Aluminum reinforced foil is used for insulation of external pipelines.

Corrugated foil has a reinforced structure. It is used for oil pipeline, water supply, gas pipeline. The corrugated aluminum foil protects against corrosion, ignition and reflects more than 97% of the thermal radiation. Laminated covered with an additional layer. Aluminum laminated foil provides better protection against penetration of moisture and has a greater thickness.

Well, and the last kind, about which it is necessary to tell is a self-adhesive. Widely used for covering joints, as well as for flexible structures. Aluminum self-adhesive foil has a small thickness.

Properties of foil

So, this material is so popular due to its performance properties. We list only a few of them. First, the ability to maintain and acquire the necessary form. You can cover it with absolutely any surface. It can be bent, folded an infinite number of times in all kinds of configurations. Secondly, resistance to corrosion.

The top is covered with a special protective layer, which also prevents the impact of aggressive components. Thirdly, the opacity. This is very important, because under the influence of UV rays, the surface state can deteriorate many times. Fourth, the lack of attraction, there is no static electricity, because of which the dust sticks. Such a problem usually exists on other film materials.
