Abstract: The instant invention provides an ethylene/alpha-olefin interpolymer composition suitable for blown film applications, and blown films made therefrom. The ethylene/alpha-olefin interpolymer composition suitable for blown film applications according to the present invention comprises greater than 80 percent by weight of units derived from ethylene and 20 percent or less by weight of units derived from one or more alpha olefin co-monomers, wherein said ethylene/alpha-olefin interpolymer has a density in the range of from 0.910 to 0.918 g/cm3, a melt index I2 in the range of from 0.5 to 1.1 g/10 minutes, a melt flow ratio I10/I2 in the range of from 8 to 10, a melt strength in the range of from 3 to 6 cN, a highest temperature fraction in the range of from 11 to 14 percent determined by CEF, a highest peak temperature fraction by CEF in range of from 96 to 100° C., and a lowest temperature fraction from CEF in the range of from 2 to 5 percent, and a DSC heat curve having three melting peaks with a highest temperature melting peak in the range of from 120 to 124° C., a crystallinity in the range of from 40 to 50 percent.
