摘要:
A multilayer film comprising a core layer and two skin layers, wherein the core layer is positioned between the two skin layers, wherein the core layer comprises a polyethylene polymer blend, the polyethylene polymer blend comprising at least 40%, by weight of the polyethylene polymer blend, of an ethylene-based polymer having a density of 0.900-0.925 g/cc and a melt index of 0.7-6 g/10 min, wherein the polyethylene polymer blend has an overall density of about 0.910-0.935 g/cc and a melt index of about 0.7-6 g/ 10 min, and wherein each skin layer independently comprises a propylene-based polymer.
