Abstract:
A film composition comprising one or more propylene-based polymers and one or more hydrocarbon resins, and methods for making the same are provided. The propylene-based polymer may have (i) 60 wt % or more units derived from propylene, (ii) isotactically arranged propylene derived sequences, and (iii) a heat of fusion less than 65 J/g. The hydrocarbon resin may have a glass transition temperature greater than 20° C.
