Abstract:
1. A blown film comprising at least one layer formed from a composition comprising at least the following: A) an olefin multi-block interpolymer, B) a functionalized olefin-based polymer, and C) a thermoplastic polyurethane, and wherein the functionalized olefin-based polymer has a density from 0.84 g/cc to 0.93 g/cc, and wherein the functionalized olefin-based polymer is functionalized ethylene/alpha-olefin interpolymer, and wherein the olefin multi-block interpolymer is present in an amount from 50 to 80 weight percent, and the thermoplastic polyurethane is present in an amount from 50 to 20 weight percent, each based on the sum weight of the olefin multi-block interpolymer and the thermoplastic polyurethane, and wherein the olefin multi-block interpolymer is an ethylene multi-block interpolymer, and wherein the functionalized ethylene/alpha-olefin interpolymer is not a functionalized olefin multi-block interpolymer; and wherein the functionalized ethylene/alpha-olefin interpolymer has a melt index (I2) from 0.5 to 50 g/10 min.
