Zusammenfassung:Provided are multi-layered white opaque films composed of at least two skin layers, at least one tie layer, and at least one core layer. The at least two skin layers are each composed of one or more polyolefins. The at least one tie layer is composed of one or more hydrocarbon resins. The at least one core layer is composed of a blend of one or more polyolefins and one or more cavitating agents. The multi-layered white opaque films described herein exhibit improvements in light transmission, stiffness, and water vapor transmission rate. Moreover, these films were found to exhibit improved cavitation as tested by optical gauge and light transmission.
