This invention pertains to polyethylene extrusion compositions. In particular, the invention pertains to ethylene polymer extrusion compositions having high drawdown and substantially reduced neck-in. The compositions comprise from 40 to 90% by weight of the composition of a first polyethylene composition, said first polyethylene composition comprising a linear low density polyethylene having a density in the range of from 0.90 to 0.96 g/cm3, and a melt index (I2) of from 5 to 15 g/10 min; and from 1 to 10% by weight of the composition of a second polyethylene composition, said second polyethylene composition comprising a high pressure low density polyethylene having a density in the range of from 0.915 to 0.930 g/cm3, and a melt index of from 0.1 to 3 g/10 min; and from 10 to 50% by weight of the composition of a third polyethylene composition, said third polyethylene composition comprising a high pressure low density polyethylene having a density in the range of from 0.915 to 0.930 g/cm3, and a melt index of from 5 to 15 g/10 min.
