Beschreibung
Zusammenfassung:	Provided are multilayer films including ethylene-based polymers. The multilayer films can be fully compatible with polyethylene recycling streams. The multilayer films comprise a first outer layer, a second outer layer, and a core, the core including a first core layer that includes an ethylene-propylene copolymer. The multilayer films of the present invention can exhibit improved, maintained, or desirable properties, such as high tear resistance, in comparison to existing multilayer film structures that are not fully compatible with polyethylene recycling streams. Se proporcionan películas multicapa que incluyen polímeros a base de etileno. Las películas multicapa pueden ser completamente compatibles con corrientes de reciclado de polietileno. Las películas multicapa comprenden una primera capa externa, una segunda capa externa y un núcleo, el núcleo incluye una primera capa central que incluye un copolímero de etileno-propileno. Las películas multicapa de la presente invención pueden exhibir propiedades mejoradas, mantenidas o deseables, tales como alta resistencia al desgarro, en comparación con las estructuras de película multicapa existentes que no son completamente compatibles con las corrientes de reciclado de polietileno.
