Abstract: Embodiments of multilayer films are disclosed comprising a first layer comprising polyethylene, a second layer comprising a first medium density polyethylene; a barrier layer; a third layer comprising a second medium density polyethylene; and a fourth layer comprising polyethylene. The second layer may be positioned between the first layer and the barrier layer. The barrier layer may be positioned between the second layer and the third layer.

Abstract: Embodiments of polyethylene compositions and articles comprising polyethylene compositions are disclosed. The polyethylene compositions may include a first polyethylene fraction area defined by an area in the elution profile in a temperature range of 70°C to 97°C via improved comonomer composition distribution (iCCD) analysis method; a first peak in the temperature range of 70°C to 97°C in the elution profile; a second polyethylene fraction area defined by an area in the elution profile in a temperature range of 97°C to 110°C; and a second peak in the temperature range of 97°C to 110°C. The polyethylene composition may have a density of 0.935 g/cm 3 to 0.955 g/cm 3 and a melt index (I 2 ) of 1.0 g/10 minutes to 10.0 g/10 minutes. A ratio of the first polyethylene fraction area to the second polyethylene fraction area may be less than 2.0.
