  • Method for producing transferable modifier-containing film
    Patent number: 5382391
    Abstract: A method for producing an extruded film article such as a bag, which is a blend of a thermoplastic polymer such as ethylene vinyl acetate and an olefinic oxide polymer such as poly(ethylene oxide), with a modifier such as liquid smoke absorbed in the blend. The modifier is transferable from the film to a receiving surface such as a food body in fluid transfer relationship with the film.
    Type: Grant
    Filed: September 23, 1993
    Date of Patent: January 17, 1995
    Assignee: Viskase Corporation
    Inventors: Roger L. Juhl, Stanley Lustig, Donatas Tijunelis

  • Meat-adhering multilayer film
    Patent number: 5051266
    Abstract: A flexible tube of multilayer film having an inner layer formed of a blend comprising EVA and an unneutralized copolymer of the ethylene acrylic acid type. At least the inner layer is irradiated. The tube is used for insitu cooking of encased meat by an aqueous bath, with resulting improved adhesions between the cooked meat outer surface and the film inner surface.
    Type: Grant
    Filed: December 1, 1989
    Date of Patent: September 24, 1991
    Assignee: Viskase Corporation
    Inventors: Roger L. Juhl, Jeffrey M. Schuetz, Stanley Lustig
  • Multilayer film tube for cook-in meat adhesion and method of making
    Patent number: 5047253
    Abstract: A flexible multilayer film tube has an inner layer comprising a blend of thermoplastic polymer and starch particles in protruding relationship with the inside surface which, after oxidation, develops improved meat adhesion during in situ cooking.
    Type: Grant

  • Stable polyamide solutions
    Patent number: 4714736
    Abstract: Polyamide solutions for imparting wet strength to paper are stabilized by acidifying uncrosslinked polyamide solutions prior to storage or prior to crosslinking with epichlorohydrin to form polyamide resins. The acidification of the uncrosslinked solutions allows for storage without refrigeration. The acidification prior to crosslinking results in wet strength resins that are stable at solids concentrations of at least 30% and that exhibit high strength when the resins are post cooked to a viscosity of between about 325 and 425 cps.

  • Molecular sieves as catalysts for preparation of 1,1,2-trichloroethane
    Patent number: 4605801
    Abstract: The process is an improvement over the chlorination of EDC in a boiling bed. The reactants, chlorine and dichloroethane (either 1,1- or 1,2-) are mixed in the vapor phase and passed over a molecular sieve which serves as a catalyst to produce 1,1,2-trichloroethane.
