    摘要: High density polyethylene barrier grade films comprising at least one layer of polymer wherein the polymer comprises a density greater than about 0.955 g/cc and a rheological breadth parameter of greater than about 0.22 are disclosed. Methods for producing such films on a film line with a neck height configuration of greater than about 15 inches are disclosed.
