Abstract: Embodiments disclosed herein include multilayer films having at least an outer layer that includes 1) polyethylene elastomer and 2) ULDPE or VLDPE and that has a purge fraction greater than 20 percent as determined by Crystallization Elution Fractionation (CEF) test method. Embodiments disclosed herein also include related compositions to make such films and methods of making such films. The ULDPE or VLDPE can be made via Ziegler-Natta catalyst reaction techniques to provide the desired purge fraction.
