Abstract: Provided are bimodal medium density polyethylene compositions, and microirrigation drip tapes including the same. The bimodal medium density polyethylene compositions can be extruded at higher lines speed while maintaining other desirable properties. The bimodal medium density polyethylene compositions include a high molecular weight (HMW) polyethylene component and a low molecular weight (LMW) polyethylene component. In some embodiments, the bimodal medium density polyethylene composition has a density of from 0.937 to 0.949 g/cm3; a high load melt index (I21) from 12 to 30 g/10 min: a crossover G′=G″ of from 30 to 45 kPa; and a calculated LMW density of the LWM polyethylene component of less than or equal to 0.974 g/cm3.
