Abstract: A tie layer composition comprising from 60 wt. to 95 wt. % of a first polyethylene composition comprising a first molecular weight ethylene-based polymer component and a second molecular weight ethylene-based polymer component, wherein the polyethylene resin has a density from 0.940 to 0.960 g/cc and a melt index (I2) from 0.01 to 5 g/10 min; and from 5 wt. % to 40 wt. % of a second polyethylene composition comprising: (i) a high density polyethylene having a density greater than or equal to 0.940 g/cc; and (ii) a maleic-anhydride grafted polyethylene.
