摘要:
High density polyethylene (HDPE) comprising narrow rheological breadth and narrow molecular weight distribution, and methods for producing such HDPE polymer are disclosed. HDPE blown resins and films produced from the HDPE of the invention, and methods of producing such resins and films are also disclosed. The novel HDPE-derived resins of the invention possess exceptional clarity and gloss in comparison to conventional HDPE-derived resin.
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.
