Abstract: Disclosed are compositions and methods for multilayer films, which, in one embodiment may comprise a core layer comprising at least 50 wt. % of high-density polyethylene. Further, the multilayer film may include a first skin layer consisting essentially of one or more ethylene-propylene copolymers. Further still, the multilayer film may include a second skin layer consisting essentially of one or more ethylene-propylene-butylene terpolymers. And yet further, the multilayer film may be oriented in at least one direction, and at least two layers of the multilayer film are coextruded.

Abstract: Disclosed are compositions and methods for multilayer films, which, in one embodiment may include a core layer comprising a polyethylene stabilizer optionally in a masterbatch solution and at least 50 wt. % of high-density polyethylene. Further, the multilayer film may include a first skin layer comprising at least 90 wt. % ethylene-propylene polymer and antiblock, and a second skin layer consisting of an ethylene-propylene copolymer or terpolymer. Further still, the multilayer film may include a primer layer on the second skin, an aqueous barrier layer of ethylene vinyl alcohol polymer, polyvinyl alcohol polymer, or combinations thereof on the primer layer. And, further still, multilayer film may include a metallization layer on the aqueous barrier layer, wherein the multilayer film may be oriented in at least one direction.

Abstract: Disclosed is a multilayered film that includes a core layer that includes one or more polymers, wherein the core has a first side and a second side and is optionally oriented. Further, the multilayered film includes a sealing layer comprising a primer and a sealing coating, wherein the primer has a primer coating weight from 0.05 to 0.5 g/m2 and is located between the first side of the core and a first side of the sealing coating, wherein the sealing coating has a sealing coating weight from 0.5 to 20.0 g/m2, wherein the multilayered film has a seal strength of at least 1 kg/in at 120° C. In various embodiments, the films showed outstanding seal strength, hot tack for both clear and white films over a broad temperature range, seal integrity under the Skye test, low blocking, and other desirable performance metrics.

Abstract: A multi-layered sealable film and method of storing and transporting a role of the film without buckling or starring, the film comprising a core layer comprising polypropylene sandwiched between at least a first and (optionally) second tie-layer on either side of the core; a sealable layer with two sides, one side adhered to the first tie-layer; wherein at least the first tie-layer comprising a blend of polypropylene and within the range of from 5 wt % to 40 wt % of a soft polymer additive, preferably a propylene-?-olefin elastomer having within the range of from 10 wt % to 30 wt % ?-olefin derived units, wherein the blend is preferably partially or completely immiscible. A roll of the inventive films can be readily stored and transported without loss due to film defects.

Abstract: A thermoplastic resin composition, containing a thermoplastic resin, comprising at least one aromatic polycarbonate resin, a flame-retarding amount of an organophosphorus flame retardant compound and a flame reatarding amount of a polyimide compound.

Abstract: An aromatic polycarbonate composition having less than 400 parts per billion each of ionic impurities, particularly sulfate, chloride and fluoride ions prepared by devolatilizing the ionic impurities from a polycarbonate composition employing an aqueous medium of about 1% by weight based on the weight of the polycarbonate composition. Preferably the devolatilizing is carried out in an extruder during compounding the polycarbonate composition and preferably under a vacuum. Also, the extruded strands of polycarbonate resin are quenched in a deionized water bath.

Abstract: The efficiency of a redistribution catalyst during polycarbonate redistribution is improved by employing an extruder screw design that provides a melt seal between the extruder throat and the vacuum port. A melt seal exists when the free volume within the extruder is sufficiently filled with molten resin so as to prevent the passage of gases between sections of the extruder.
