Abstract
A bimodal polyethylene-based composition that is useful for making under film extrusion conditions a film that beneficially has both decreased water vapor transmission rate and decreased haze. The composition comprises an improved design of the composition of the polyethylene blend of a higher molecular weight polyethylene polymer constituent and a lower molecular weight polyethylene polymer constituent and an effective amount of a nucleating agent. Additional embodiments include a method of making the bimodal polyethylene-based composition, a formulation comprising the bimodal polyethylene-based composition and at least one additive, a method of making a manufactured article from the bimodal polyethylene-based composition or formulation; the manufactured article made thereby, use of the bimodal polyethylene-based composition for protecting a moisture-sensitive material, and a sealed package made therefrom.
