Inelastic film structures including at least one layer incorporating a combination of a first polymeric component that is at least one polymer incorporating propylene-derived units and a second polymeric component that is a thermoplastic polymer, for example, a polymer incorporating a polyolefin, are provided. The combination of the first polymeric component and the second polymeric component incorporates from about 40 wt. % to about 98 wt. % of the at least one polymer incorporating propylene-derived units and from about 2 wt. % to about 60 wt. % of the at least one polymer incorporating a polyolefin. The film structures are found to have properties making the structures useful for inclusion in a variety of applications. In certain embodiments, the film structures may exhibit optical clarity, tack, sealability, toughness, softness, and machinability properties superior to conventional polypropylene films and other conventional polyolefin films.
