1. An ethylene polymer composition comprising(A) from about 10 percent (by weight of the total composition) to about 95 percent (by weight of the total composition) of at least one ethylene interpolymer having:

  • (i) a density from about 0.89 grams/cubic centimeter (g/cm3) to about 0.935 g/cm3,(ii) a melt index (I2) from about 0.001 grams/10 minutes (g/10 min.) to about 10 g/10 min.,(iii) a slope of strain hardening coefficient greater than or equal to 1.3, and(iv) a Composition Distribution Branch Index (CDBI) greater than 50 percent; and

    (B) from about 5 percent (by weight of the total composition) to about 90 percent (by weight of the total composition) of at least one ethylene polymer characterized as having a density from about 0.93 g/cm3 to about 0.965 g/cm3 and comprising a linear polymer fraction, as determined using a temperature rising elution fractionation (TREF) technique.
