    The heart of blown film extrusion is screw part, the screw and barrels for blown film extrusion machine Nan Yun designed is 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.
