{HEAD ~ The aggregate polymer throughput} of the nozzle system 1 is more than about 1 kg/hr/m, particularly may range from 1 to 200 kg/hr/m, more particularly from 10 to 200 kg/hr/m, and most particularly between 25 and 70 kg/hr/m. Per orifice, the polymer throughput can be more than about 1, particularly more than about 50, and more particularly more than about 1000 gram per minute per {TAIL ~ orifice}
