Abstract
A film comprising one or more propylene-based polymers, one or more hydrocarbon resins, and one or more polyolefin additives provides enhanced mechanical and elastic properties compared to the neat propylene-based polymer. The propylene-based polymer may have (i) 60 wt % or more units derived from propylene; and (ii) crystallinity of from 0.25% to 40%, resulting from isotactically arranged propylene-derived sequences. The hydrocarbon resin may have a glass transition temperature greater than 20° C. The polyolefin additive may have a crystallinity greater than the crystallinity of the propylene-based polymer. Methods for making and using the films are also described.
