Abstract
An oriented multi-layer film comprised of a core layer comprising a metallocene-catalyzed substantially isotactic propylene polymer, a first additional layer on a side of the core layer, and a second additional layer on a side of the core layer which side is opposite to the side having the first additional layer. In one embodiment of the invention, the core layer includes a polymerized alicyclic hydrocarbon such as polyterpene.
