==== Metallocene polyethylene (PE-MC) ====
Metallocene polyethylene (PE-M) is prepared by means of [[metallocene catalysts]], usually including copolymers (z. B. ethene / hexene). Metallocene polyethylene has a relatively narrow [[molecular weight distribution]], exceptionally high toughness, excellent optical properties and a uniform comonomer content. Because of the narrow molecular weight distribution it behaves less pseudoplastic (especially under larger shear rates). Metallocene polyethylene has a low proportion of low molecular weight (extractable) components and a low welding and sealing temperature. Thus, it is particularly suitable for the food industry.<ref name="Kaiser" />{{rp|238}}<ref name="Vasile">{{cite book|last1=Pascu|first1=Cornelia Vasile: Mihaela|title=Practical guide to polyethylene|date=2005|publisher=Rapra Technology Ltd.|location=Shawbury|isbn=978-1859574935|edition=[Online-Ausg.].}}</ref>{{rp|19}}
