Abstract

LDPE (Low density Poly ethylene) was melt blended with micro clay (0.5, 1, 3 & 5 wt%) by using a twin screw compounding extruder. Tubular blown film was taken using a tubular blown film extruder. Mechanical, optical and barrier properties were evaluated.  The following trend was observed  as the micro clay concentration was increased: The tensile strength was increased by 18% in machine direction (M/D) and decreased by 36% in transverse direction (T/D). The Elongation at break was lowered in both Machine and transverse directions.    The tear strength was increased by 158 and 50%  in   M/D and T/D respectively. Dart impact strength was increased by about 95%.  MFI decreased and density increased. WVTR  decreased by  90% and oxygen gas permeability  80% decreased. Haze increased by 20% and clarity slightly decreased by 2%.
