Abstract

A multilayer film is disclosed, having at least two layers. A first layer includes a first interpolymer of ethylene and at least one alpha-olefin. The first interpolymer has a density of less than 0.925 g/cm3, and an average Mand a valley temperature between the interpolymer and high crystalline fraction, T, such that the average Mfor a fraction above Tfrom ATREF divided by average Mof the whole polymer from ATREF (M/M) is less than about 1.95 and the first interpolymer has a CDBI of less than 60%. At least one other second layer includes a second inter-polymer of ethylene and at least one alpha-olefin, the second interpolymer having a density from 0.925 to 0.965 g/cm3. The interpolymer of ethylene and at least one alpha-olefin can have a high density fraction and an overall density such that % HD fraction <0.0168x2−29.636x+13036 where x=density in g/cm3.
