Abstract: Applicants have discovered that certain polyethylene (PE) homopolymers or copolymers of ethylene and C3 to C-f o alpha-olefin monomers are more suitable for oriented processes than other polyethylene resins. In an aspect, the PE has a MFI of 0.3 g/10 min. to 5.0 g/10 min,, a melting point of from 11O0C to 140°C, a density of from 0.912 g/cm 3 to 0.965 g/cm 3 (%), a haze of 10% or less, a clarity of at least 90, and a gloss of at (east 60. The polyethylene is heated and formed into an article, cooled, and then the article is stretch oriented. In an embodiment, the film, tape, the melt extruded, injection blow molded, injection stretch blow molded, cast, and thermoformed articles that can be produced with this polyethylene has a thickness of 0.1 miI to 100 mils. The polyethylene exhibits excellent elasticity, toughness, stretch and optical properties for such applications.

Abstract: This invention relates to high density polyethylene blown films having good barrier properties and improved processing characteristics. The method incorporates the use of peroxide which results in improved bubble stability without sacrifice in barrier properties. The polyethylenes have a density greater than about 0.950g/cc, are relatively narrow in molecular weight distribution MWD (in the range of from about 2.0 to about 6.5), and are of medium molecular weight. In an embodiment, the films also have a rheological breadth parameter, a, that has been reduced by at least about 5%, but not more than 45%, by addition of a peroxide to the polyethylene. The addition of peroxide improves processability without sacrificing strength and barrier properties such as oxygen transmission rate.
