  • Patent number: 11084258
    Abstract: The present disclosure provides a film. In an embodiment, a multilayer film having at least three layers is provided. The multilayer film includes two skin layers, each skin layer composed of a blend of a low density polyethylene and an ethylene-based elastomer having a density less than 0.90 g/cc. The multilayer film also includes a core layer located between the skin layers. The core layer includes a propylene-based plastomer having a density less than 0.90 g/cc. The multilayer film has an onset end temperature from 90° C. to 110° C. and a heat seal strength at 120° C. from 1.5 N/cm to 2.5 N/cm.

  • Publication number: 20170334176
    Abstract: A multi-layer shrink film comprising, consisting of, or consisting essentially of at least two layers, Layer A and Layer B, wherein Layer A is at least one skin layer comprising an amorphous glassy polymer material and Layer B is at least one core layer comprising i) 15-100 weight percent of a maleic anhydride-modified plastomer having a density in the range of 0.86-0.925 g/cm3; and ii) optionally a polyolefm which does not contain maleic anhydride having a density in the range of 0.86-0.925 g/cm3 and wherein the multi-level shrink film has an overall density of less than 1.0 g/cm3, is disclosed.
