Versalis Clearflex® CHH 196 Film Grade LLDPE
Categories:	Polymer; Thermoplastic; Polyethylene (PE); Linear Low Density (LLDPE); Linear Low Density Polyethylene (LLDPE), Film Grade; LLDPE/Hexene, Film Grade
Material Notes:	Clearflex® H&T CHH 196 is a hexane copolymer linear low density polyethylene (C6-LLDPE), with antioxidants, suitable for cast film extrusion. Stretch films manufactured with Clearflex® H&T CHH 196 have outstanding fracture mechanical properties, mainly Elmendorf tear strength along machine direction (MD) and puncture resistance. Moreover, the holding force is the key property of these films when used in automatic wrapping machines. Application: Clearflex® H&T CHH 196 is recommended for production of super-power stretch films. Its properties, especially in terms of holding force and puncture resistance, make Clearflex® H&T CHH 196 the ideal choice for packaging goods of irregular shape and for applications requiring a superior mechanical strength. Property data reported for cast film extruded between 220°-270°C, line speed between 150-300 m/min and thickness 23 µm. Information provided by Versalis.
