  • Polyethylene compositions and films formed thereform having improved moisture vapor transmission rates
    Patent number: 6765048
    Abstract: A novel composition is provided comprising a specified polyethylene component and a filler such that a film formed from the composition is characterized by having increased moisture vapor transmission rate. Also disclosed is a novel polyethylene composition useful in producing film.
    Type: Grant
    Filed: June 21, 2002
    Date of Patent: July 20, 2004
    Assignee: Eastman Chemical Company
    Inventors: Kathryn Kobes Dohrer, Wesley Raymond Hale, Irving Daniel Sand, Mark Alan Edmund, Martin Ray Tant, Emmett Dudley Crawford, Edward Philip Savitski, Dennis Brannon Barr
  • Organoclays as processing aids for plasticized thermoplastics
    Patent number: 6596802
    Abstract: This invention describes the use of organoclays as additives to plasticizers to provide a plasticizer composition, to allow the mixing of the plasticizers with thermoplastic resins in the same process used to convert the resin formulation to finished product. The use of this invention eliminates the need for a preliminary compounding step to incorporate plasticizers into thermoplastics prior to extrusion or molding.

  • Economical oxygen barrier structures utilizing EVOH/polyolefin blends
    Publication number: 20020150704
    Abstract: A laminate structure for both packaging and non-packaging applications, including a five layer coextrusion composite containing an EVOH/polyolefin composite barrier layer coated or applied to a paper or paperboard substrate. The laminated structure may contain a layer of linear low density polyethylene or other layers, as needed for the application. The EVOH/polyolefin blend layer is preferably a blend of an ethylene vinyl alcohol copolymer having 44% ethylene moiety and a low density polyethylene polymer. The blend barrier, which is part of a five layer coextrusion composite layer provides improved oxygen and moisture barrier characteristics to a package, prepared from such a laminated structure, as well as improved rigidity and heat resistance, thereby providing longer shelf life and excellent flavor retention to the stored contents as well as improved dimensional stability to the cartons, package or containers, at a reduced cost.
