    摘要: Disclosed in one aspect is a film comprising at least one core layer comprising a blend of at least 20 wt %, by weight of the core layer, of a first linear LLDPE having a molecular weight distribution (Mw/Mn) within the range of from 1.0 to 4.0; and at least 20 wt %, by weight of the core layer, of a second LLDPE—in a certain embodiment a short-chain branched LLDP—having a molecular weight distribution (Mw/Mn) within the range of from 1.0 to 7.0; characterized in that the density of the second LLDPE is greater than the density of the first LLDPE by at least 0.002 g/cm3; and/or the I2 of the second LLDPE is greater than the I2 of the first LLDPE by at least 0.5 dg/min. In certain embodiments, the first and second LLDPEs are produced by a metallocene-catalyzed reaction. In yet another embodiment, the combined molecular weight distribution (Mw/Mn) of the first and second LLDPEs is greater than 4.0.

    摘要: The invention discloses an ink-based-image-bearing substrate. This substrate includes a coextruded thermoplastic film having at least one layer made from a polymer derived from polypropylene and another layer made from an acidic functional group-bearing polymer. The layer which includes the polymer derived from the polypropylene is oriented in at least the machine direction. The layer which includes the acidic function group-bearing polymer is the print-receiving layer. The acidic functional group bearing-polymer is preferably ethylene-acrylic acid or ethylene-methacrylic acid, and the acidic functional group-bearing polymer-containing layer has a softening point in a range of 180° to 220° F. Liquid toner ink is electrostatically printed on the layer which includes the acidic functional group-bearing polymer. Additionally, the invention includes a method for providing the ink-based-image-bearing substrate.

    摘要: Multi-layer films particularly suited for packaging applications, including a core layer, the core layer having at least one nucleating agent and at least one water vapor transmission inhibitor are provided. Optionally, the multi-layer film may have at least one skin layer and at least one tie layer located intermediate the core layer and the at least one skin layer. Embodiments may have the advantage of superior barrier properties and very low water vapor transmission rates.
