This invention relates to cast films prepared from interpolymer compositions comprising; (A) a substantially linear ethylene/&agr;-olefin interpolymer present in the composition in an amount of from about 10 to about 100% by weight based on the combined weight of Components A and B; and (B) a heterogeneous interpolymer present in the composition in an amount of from about 0 to about 90% by weight based on the combined weight of Components A and B; and wherein said interpolymer composition has an I10/I2 value of −1.2−1.3* log(I2) The interpolymer compositions are useful in cast stretch film manufacture with the resulting cast films having an excellent balance of strength and processability.
