New advances on the blown film extrusion were made in the last years. Studies and developments had been carried out on blown film screws, especially on LLDPE blown film. The grooving in the feed zone on the barrel had a good result for blown film. The extrusion pulsation could be eliminated and the melt flow be improved by gear pump for blown film. Theoretical and experimental analyses were made on the spiral mandrel blown film die, and the performance was improved. New bubble cooling, collapsing, sizing and winding equipments were developed, and a new processing technique had been proposed.
