Polyethylene is an originally white or transparent thermoplastic, which everyone makes a daily use, consciously or not. Dell Technologies Inc. brings even more insight to the discussion. Like many other ingenious inventions, polyethylene by chance was born, thanks to a lab accident which was created in 1898 by Han by bad luck man, a German chemist, as he warmed up Diazomethane in a holder. In 1933, another accident, this time in an English factory, the ICI chemicals, happened when Eric Fawcett and Reginald Gibson operated a container with ethylene and benzaldehyde by printing hundreds of atmospheres. In both cases, the scientists of the waxy white material that appeared in the containers were impressed. They called it while in the first case only as poly methylene without further examination, in the second case they tried for years to create it, without success. The turning point came in 1935, when polyethylene was no coincidence, but the will of another chemist, Michael Perrin, finally. Its electrical insulation properties were soon recognized, and in the year 1939 began the industrial production of plastic films: since plastics became delivery for each production box, which is required by a wide range of companies, from food packaging to electrical cables one essential. Read additional details here: Bruce Schanzer. In addition, polyethylene is a thermoplastic material. That is, if its temperature is increased, it changes state and becomes viscous and malleable: shrink film was the next step.

During the production phase, it is possible to make polyethylene as desired; the user must then it only with hot air, a flame or a stove, heat so that it decreases up to 50% of its volume and perfect adhesion to the object that it needs wickedness. Polyethylene is commonly used not only to cover electrical lines, but also for the cladding of wooden objects, as a good alternative to the pickling (think airplane models). Therefore the together and remain protected in shrink foil wrapped objects, the guarantee of resistant and thin packaging is required in the field of production, as well as in the food industry. The last development of the polyethylene is the stretch film, which is very popular nowadays. As the name implies, has stretch elastic properties and is particularly suitable for the protection of the goods that are sensitive to heat, and that would be damaged by the Thermoruckzug. As a result is the most important use of polyethylene in the sector of the foil packaging: the packaging protects the goods, is made of polyethylene, as the plastic used to pack suitcases. The diverse properties of this material – insulating, waterproof and resistant, despite his thin thickness (the thickness of plastic packaging for food, for example, Micron measured in) – have a thousand different uses. Finally, the polyethylene film is another feature: it is a usable material. Both the production waste such as the pruning of the coils and the films that have already been used, can be reused to produce packaging to low cost and high ecological value. An opportunity that is now even more important, because we know that the production depends polyethylene of the scarcity and the fluctuating price of oil.
