| Clearflex H&T CMH 108 is an octene copolymer linear low density polyethylene (C8-LLDPE), with antioxidants, suitable for cast film extrusion. Stretch films obtained from Clearflex H&T CMH 108 show excellent optical properties, high puncture and tear resistance along machine direction together with excellent performances in automatic wrapping machines (prestretch). Main Application Clearflex H&T CMH 108, for its rheological behaviour, is recommended in all special applications where ease of processing is a key issue. Moreover, thanks to a optimum combination between fracture mechanical properties (mainly puncture and MD Elmendorf tear resistance) and pre-stretch performances, Clearflex H&T CMH 108 is suggested to manufacture super power stretch cast film.&& |
