Abstract
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 0.900-0.935 g/cc and a melt index of 0.7-6 g/10 min, wherein the polyethylene polymer blend has an overall density of about 0.910-0.945 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.
Claims15
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 0.900-0.935 g/cc and a melt index of 0.7-6 g/10 min, wherein the polyethylene polymer blend has an overall density of about 0.910-0.945 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;
- and where the skin layer is not a non-woven material.
A multilayer film comprising:
- a core layer;
- 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 0.900-0.935 g/cc and a melt index of 0.7-6 g/10 min, wherein the polyethylene polymer blend has an overall density of about 0.910-0.945 g/cc and a melt index of about 0.7-6 g/10 min;
- a first layer that contact the core layer;
- where the first layer comprises a propylene-based polymer;
- where the first layer is not a non-woven material;
- and
- a nonwoven substrate at least partially ultrasonically bonded to the first layer on a surface that is opposed to a surface that contacts the core layer.
