10 Claims

1. A polyethylene-based composition suitable for packaging applications comprising:

(a) at least 97% by weight, based on the total weight of the polyethylene-based composition, of a polyethylene composition comprising:

(i) from 25 to 37 percent by weight of a first polyethylene fraction having a density in the range of 0.935 to 0.947 g/cm³and a melt index (I₂) of less than 0.1 g/10 minutes; and

(ii) from 63 to 75 percent by weight of a second polyethylene fraction; and

(b) 90 to 540 ppm, based on the total weight of the polyethylene-based composition of a calcium salt of 1,2-cyclohexanedicarboxylic acid;

wherein the polyethylene composition has less than 0.10 branches per 1,000 carbon atoms when measured using ¹³C NMR, wherein the density of the polyethylene-based composition is at least 0.965 g/cm³, and wherein the melt index (I₂) of the polyethylene-based composition is 0.5 to 10 g/10 minutes.
