    摘要： This invention relates to an improved shrink film obtained by selectively controlling and optimizing the melt index and density differential between at least two polyolefin polymer components to provide narrow density splits. One aspect of this invention relates to a biaxially oriented polyolefin shrink film having balanced properties and another aspect of this invention relates to an oriented shrink film having improved toughness. This invention also relates to a biaxial orientation method of making an improved shrink film using elaborate shrink orientation techniques such as tenter framing, double-bubble, trapped bubble, tape orientation or combination thereof. Most preferably, the first polyolefin polymer component is a lower density, substantially linear ethylene/&agr;-olefin interpolymer and the second polyolefin polymer component is a higher density, heterogeneously branched ethylene/&agr;-olefin interpolymer.

    摘要： The present invention pertains to an ethylene interpolymer composition characterized as having a narrow molecular weight distribution (MWD) and optimized compositional uniformity, a process for making such a composition and a fabricated article made from such composition. The novel composition is characterized as having at least two polymer components, the first component having an ATREF peak temperature, Tpeak1 and a viscosity average molecular weight, Mv1, and the second component having an ATREF peak temperature, Tpeak2, and a viscosity average molecular, Mv2, wherein the temperature differential between Tpeak2 and Tpeak1 decreases with increased composition density and Mv1/Mv2 is less than or equal to 1.2. The novel composition is further characterized as having a Mw/Mn of less than or equal to 3.3 as determined by gel permeation chromatography, an I10/I2>6.6, and a composition density less than 0.945 gram/cubic centimeter. The novel composition exhibits high, balanced toughness properties, good processibility and surprisingly improved optical properties and is particularly well-suited for use in applications such as lamination films trash can liners and heavy duty shipping bags, especially as a blown film.
