  • Patent number: 10343304
    Abstract: Polymer composites containing carbon nanotubes often exhibit high glass transition temperatures, which can complicate their use in additive manufacturing processes. Extruded filaments containing carbon nanotubes and residual solvent can have desirably lowered glass transition temperatures. Extruded filaments can contain a polymer as a continuous phase, a nanomaterial such as carbon nanotubes homogeneously mixed throughout the continuous phase, and above 0% to about 15% solvent by weight.

  • Patent number: 9447269
    Abstract: The present invention relates to a film having a combination of good flexibility and excellent barrier properties. The film comprises at least one barrier layer. The barrier layer comprises at least 5 percent, by weight of the layer, of an anhydride and/or carboxylic acid functionalized ethylene/alpha-olefin interpolymer having a density in the range of from 0.855 to 0.900 g/cm3; and having a melt index (190° C./2.16 kg) of greater than 200 g/10 min. The barrier layer further comprises at least 60 percent, by weight of the layer, of an interpolymer derived from ethylene and vinyl alcohol monomer units.

  • Patent number: 9434138
    Abstract: A heat-sealable polymer-based multilayer film for peelably and releasably packaging pasty or fatty foods comprising a polymer-based core layer having a food-facing side and an exterior-facing side, a peelable layer on the food-facing side of the core layer, the peelable layer having a food-facing side and a core-facing side, and the peelable layer containing a peeling agent, and an interior skin layer on the food-facing side of the peelable layer, the interior skin layer having a food-facing side and a core-facing side. The core layer contains a release agent for diffusion toward the interior skin layer, and the release agent is present in the core layer in a quantity which is greater than the saturation capacity of peeling agent in the peelable layer for the release agent.

  • Patent number: 9393729
    Abstract: A method is disclosed that includes forming a plurality of polymer layers via a plurality of slots, wherein the plurality of layers are combined to generate a multilayer polymer flow stream; and controlling heat flow to the plurality of slots in conjunction with the formation of the plurality of polymer layers. The multilayer polymer flow stream may be used to generate a multilayer film. In some embodiments, the cross-web layer thickness profile may be controlled by controlling heat flow to the plurality of slots that form the plurality of polymer layers.
