Abstract: A biaxially oriented polyethylene film structure comprises at least three layers, including a core layer, wherein the core layer comprises: i) from 50 to 99.5 weight percent of a first polyethylene which is an ethylene copolymer having a density of greater than 0.940 g/cm3; and ii) from 0.5 to 50 weight percent of a second polyethylene which is a polyethylene homopolymer composition having a density of at least 0.950 g/cm3; wherein the polyethylene homopolymer composition further comprises a nucleating agent or a mixture of nucleating agents. The biaxially oriented film has very good optical properties.

Abstract: An ethylene copolymer comprising ethylene and at least one alpha olefin having from 4 to 8 carbon atoms has a density f from 0.940 to 0.960 g/cm3, a molecular weight distribution, Mw/Mn of from 9 to 12, and a Z-average molecular weight, Mz of greater than 500,000. The ethylene copolymer is made in a multi-zone reactor system under solution phase polymerization conditions and is useful in the preparation of biaxially oriented polyethylene (BOPE) films.

Abstract: A Biaxially Oriented Polyethylene (BOPE) process uses a selected polyethylene having a medium density and a very broad molecular weight distribution. The use of this selected polyethylene facilitates stretching in the BOPE process in comparison to previously used polyethylene resins having a higher density and/or a narrower molecular weight distribution.
