Abstract
A multilayer polyethylene film comprising a core layer, a first outer layer, and a second outer layer, wherein the core layer is positioned between the first outer layer and the second outer layer, the core layer comprises a linear low density polyethylene and, optionally, a first low density polyethylene resin, and the first outer layer and the second outer layer independently comprise a polyethylene resin and, optionally, a second low density polyethylene resin, wherein the density of the linear low density polyethylene is less than the density of the polyethylene resin.
Claims9
A multilayer polyethylene film comprising a core layer, a first outer layer, and a second outer layer, wherein:
- the core layer is positioned between the first outer layer and the second outer layer;
- the core layer comprises a linear low density polyethylene having a density of 0.900 g/cc to 0.935 g/cc and a melt index, I2, of 0.1 g/10 min to 10 g/10 min, and, optionally, a first low density polyethylene resin having a density from 0.915 g/cc to 0.935 g/cc and a melt index, I2, from 0.1 g/10 min to 15 g/10min;
- and
- the first outer layer and the second outer layer independently comprise a polyethylene resin having a density of 0.935 g/cc to 0.970 g/cc and a melt index, I2, of 0.1 g/10 min to 15 g/10 min and, optionally, a second low density polyethylene resin having a density from 0.915 g/cc to 0.935 g/cc and a melt index, I2, from 0.1 g/10 min to 15 g/10 min;
- wherein the density of the linear low density polyethylene is less than the density of the polyethylene resin,
- wherein the first outer layer comprises from 5 wt. % to 40 wt. % of the second low density polyethylene resin, based on the total weight of polymers present in the first outer layer.
