A polymeric resin having a density of greater than 0.960 g/cc, a melt index of from 1.3 g/10 min. to 2.8 g/10 min., a zero shear viscosity of from Ix 104 Pa*s to 1 x 105 Pa*s, a recoverable shear parameter of from 220 to 370, and a CY-a parameter of from 0.155 to 0.200. A polymeric resin having an initial tension defined by the equation IT>-1.67*(MI)+b where b is 5.17 and a percent decrease in the extrusion pressure of the resin of 30% when compared to polymer resin of similar melt index prepared with a catalyst that has not undergone an activation comprising an oxidation, reduction, oxidation sequence wherein the resin when formed into a film has a moisture vapor transmission rate of from 0.21 g.mil/100 in2/day to 0.33 g.mil/100 in2/day. |
