The present invention provides for a polymer composition comprising a blend of from about 25 to about 90% by weight of a very low density ethylene polymer having a density on the range of from about 0.88 to 0.925 g/cm.sup.3, a melt index of from about 0.5 to about 7.5 dg/min, a molecular weight distribution not greater than about 3.5 and a compositional distribution breadth index greater than about 70%, and from about 10 to about 75% by weight of a low to medium density ethylene polymer having a density of from about 0.910 to about 0.935, a melt index of from about 0.5 to about 20, a molecular weight distribution greater than about 3.5 and a compositional breadth index less than about 70%. The invention also provides for films prepared from this blend having single layer construction or having laminar ABA construction wherein the A or skin layers comprise the blend of this invention and the B or core layer comprises a different olefin polymer such as high density polyethylene. Films of this invention exhibit excellent elongation, tensile and impact properties and also softness, feel and noise properties which render them eminently suitable for use as back sheet components in the fabrication of absorbent articles such as diapers, bed pads and like articles where such properties are desirable.
