Blown Film Extrusion of LLDPE/LDPE Blends
Journal of Reinforced Plastics and Composites, 1999 An experimental study was carried out to investigate the effect of LLDPE/LDPE blend compositions on the physical properties of blown films and processing properties during extrusion. Spiral mandrel die analysis was also performed by FAN method and its results were compared with measured die pressure. Positive synergy effects of LDPE addition into LLDPE
