Abstract

Cast films were prepared using a Killion single screw extruder, from a range of metallocene PEs of varied comonomer types (hexene, octene), using different haul off speeds (8-4m/min) and die gaps (700-250µm). It was found that samples with greater orientation in one direction had increased tensile strength and shrinkage in that direction. DSC analysis showed crystallinity to decrease with
decreasing haul off speed
