Abstract
Heat-sealable, oriented, multilayer films including i) a polyolefin core layer; and ii) a heat-sealable layer a blend of 10.0 wt % to 50.0 wt % of a propylene-based elastomer and 50.0 wt % to 90.0 wt % of a propylene-based polymer, wherein the heat-sealable layer includes less than 1.0 wt % ethylene homopolymer or ethylene-based copolymer and wherein the heat-sealable layer has a Haze of ≦5.0 and a seal strength of ≧2.00×102 g/2.54 cm at 82° C. (180° F.). In particular films, the heat-sealable layer has a Haze of ≦5.0 and a seal strength of ≧3.00×102 g/2.54 cm at 90° C. (194° F.). Methods of making such multilayer structures and articles made therefrom are also disclosed.
