1. A polymer blend composition comprising:

  • a plurality of linear ethylene interpolymer components comprising ethylene and at least one alpha-olefin comonomer, each component having a different average molecular weight, a Mw/Mn≦

    3, a composition distribution breadth index of at least 50% and a density greater than or equal to 0.900 g/cm3 ;

    the composition having a density greater than or equal to 0.900 g/cm3 and a Mw/Mn>

    3;

    wherein the composition is essentially free of components having a higher average molecular weight and a lower average comonomer content than that of any other components.
