The Accident ! • Polyethylene was first synthesized by German chemist Hans von Pechmann who prepared it by accident in 1898, while heating diazomethane on the stove. When his colleagues Eugen Bamberger and Friedrich Tschirner investigated the white oily substance created, they discovered long chains composed of-CH2-and called it polymethylene. March 27, 1933, in England, was synthesized as we know it today, by Reginald Gibson and Eric Fawcett who worked for ICI Laboratories.

Characteristics • • • • • • • Excellent electrical insulator. . Transparent, opaque or attractive colors. . Resistant to low temperatures. . Hygienic and safe. . Inert to chemical attack. . Excellent moisture barrier. . Economic.

Its Uses • All sorts of bags : supermarkets, boutiques,bakery,frosts etc. • Coating ditches • Automatic food packaging and industrial products, such as Milk, water, plastics, etc. • Base for disposable nappies. • Serum bags. • Domestic airtight containers • Pipes and knobs: cosmetics, medicines and food • Irrigation pipes • Bottles , draws

Recycling ! The Polyethylene is recyclable,it means, that we can melt it again and transform it in new products such as plastic wood for sticks film for agriculture etc.
