摘要
LDPE (low-density polyethylene) was melt blended with microclay (0.5, 1, 3 and 5 wt%) by using a twin-screw compounding extruder. The 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 microclay concentration was increased: The tensile strength was increased by 18% in the machine direction (M/D) and decreased by 36% in the 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%.
