    Abstract: Films (or a cap layer of co-extruded films) and methods of forming the same are described herein. The films generally include a modified olefin based polymer including polypropylene and from 1 wt. % to 30 wt. % polylactic acid (PLA), wherein the modified olefin based polymer exhibits a seal initiation temperature (SIT) that is at least 5° C. less than a seal initiation temperature of the polypropylene absent the PLA and a hot tack range of at least 20° C.
