A multilayer film is prepared from a high impact strength polyethylene (HI polyethylene); a Ziegler Natta catalyzed polyethylene (Z/N polyethylene) and a high pressure low density polyethylene (LD polyethylene) with i) at least one skin layer consists essentially of HI polyethylene and ii) at least one core layer comprises a blend of Z/N polyethylene and said LD polyethylene. The HI polyethylene has a density of from 0.915 to about 0.930 g/cc and a normalized impact strength of at least about 300 g/mil. The amount of HI polyethylene is from about 30 to about 55 weight % (based on the combined weights of the HI+Z/N+LD polyethylenes). The films described herein are readily prepared on blown film equipment and provide an excellent balance of mechanical properties.
