Beschreibung
Zusammenfassung:	The present disclosure provides a multi-layer film. The multi-layer film includes a first outer layer and a second outer layer, where at least one of the first and the second outer layers comprises a first polyethylene; a core layer between the first and second outer layers, where a thickness of the core layer is 8 to 30% of a total thickness of the multi-layer film. The core layer is formed from a core polymer comprised of 20 to 0 wt. % of a second polyethylene and 80 to 100 wt. % of a propylene-based elastomer having a density of 0.855 g/cm3 to 0.877 g/cm3, the wt. % based on a total weight of the core layer. The multi-layer film comprises 8 to 30 wt. % of the propylene-based elastomer, based on a total wt. % of the multi-layer film. The multi-layer film also includes a first and a second inner layer, where at least one of the first and the second inner layers comprises 80 to 100 wt. % of a LLDPE having a density of 0.870 g/cm3 to 0.912 g/cm3 and 20 to 0 wt. % of a LDPE, where the core layer is positioned between the first and the second inner layers.
