Polyethylene as the material for marking tapes
or stretch foil
Its primary use is in packaging (plastic bags, plastic films, geomembranes, containers including bottles, etc.).
Polyethylene or polythene (PE) is the most common plastic. PE is usually a mixture of similar polymers of ethylene with various values of n. Polyethylene was first synthesized by the German chemist Hans von Pechmann, who prepared it by accident in 1898 while investigating diazomethane. When his colleagues Eugen Bamberger and Friedrich Tschirner characterized the white, waxy substance that he had created, they recognized that it contained long –CH2– chains and termed it polymethylene.
The properties of polyethylene can be divided into mechanical, chemical, electrical, optical, and thermal properties. Polyethylene is of low strength, hardness and rigidity, but has a high ductility and impact strength as well as low friction. It shows strong creep under persistent force, which can be reduced by addition of short fibers. It feels waxy when touched.
