Zusammenfassung:	A multi-layered film comprising at least 3 layers is provided. When a 5 layered film is provided, the film includes a first outer layer having 80% to 100% by weight of one or more polyolefins, a first tie layer having from 5% to 100% by weight of the first tie layer of one or more functionalized polyolefins, a core layer having from 75% to 100% by weight of the core layer of polylactic acid, a second tie layer having from 5% to 100% by weight of second tie layer of one or more functionalized polyolefins, and a second outer layer having from 80% to 100% by weight of the second outer layer of one or more polyolefins, wherein the first tie layer layer is disposed between the first outer layer and the core layer the second tie layer is disposed between the core layer and the second outer layer.
