    The heart of the blown film extruder is the screw part, the screws and barrels for the blown film extruder designed by Nan-Yun are able to deliver optimally developed polymer melt, at rates that meet the throughput target of the processor. Furthermore, the screw and barrel we designed for blown film plant or inflation machine also can have outstanding performance on melt quality, meilt temperature and gauge uniformity.
