    摘要: Provided is a squeezable oriented polypropylene adhesive film that can be formed into a label comprising at least one core layer sandwiched between at least two skin layers, the layers comprising: a core layer comprising a polypropylene and within the range of from 20 wt % to 50 wt %, by weight of the materials in the core layer, of a propylene-α-olefin elastomer having within the range of from 5 wt % to 25 wt % α-olefin derived units, by weight of the elastomer; a printable skin layer comprising within the range of from 60 wt % to 100 wt %, by weight of the materials in the printable skin layer, or an α-olefin copolymer comprising at least 30 wt % ethylene; and an adhesive-accepting skin layer comprising within the range of from 60 wt % to 100 wt %, by weight of the materials in the adhesive-accepting skin layer, of a polypropylene.

    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.
