Extruder-blown film-bag manufacturing

Ternary blends contained 87-96 wt% LLDPE (with either butene-1, hexene-1, or octene-1), 1-10 wt% isotactic polybutene, 1-10 wt% PS, and 0.01-10 wt% color and anti-blocking agents. The blends exhibited improved process efficiency in terms of extruder amps/ rpm ratio, while the terpolymer substantially retained the inherent strength of the LLDPE. The compositions were used for blown films and for the manufacture of waste bags ...
