Abstract
Applicants have discovered that certain polyethylene (PE) homopolymers or copolymers of ethylene and Cto Calpha-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 110° C. to 140° C., a density of from 0.912 g/cmto 0.965 g/cm(%), a haze of 10% or less, a clarity of at least 90, and a gloss of at least 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 mil to 100 mils. The polyethylene exhibits excellent elasticity, toughness, stretch and optical properties for such applications.
