Parametric Performance Analysis of LLDPE Blown Film for Tensile Strength, Gauge and Yield with Calcium Carbonate Filler

The blown film machine is design to manufacture blown film from HDPE, LLDPE, LDPE. Over past few year, much intrest has been placed in to the investigation of increased mechanical properties of blown film via multitude approaches. In this work use LLDPE O19010 base polymer grade and calcium carbonate use as a filler. To evaluate the cross linking effect of ca+2 cation film made from caco3. The production of blown film is carried out in two steps. First thermoplastic pellet are processed in dryer then they transferred in to thin film using a classic film blowing machine. In this study use taguchi method with 3 level of factor which are caco3 %, dryer temperature, motor rpm, inflation pressure, die exit temperature and produce the film from this factor. After this bubble diameter, BUR, gauge, tensile strength, elongation and yield measurement is carried out.
