  • Bonded fibrous casing substrates and method of making same
    Patent number: 5419962
    Abstract: A porous fibrous sheet material for use in the manufacture of food casings and the like is pressed prior to bonding and is bonded with about 10% by weight or less of a non-viscose bonding agent. The pressed and bonded material can be used to form casings having characteristics of thinness and elasticity similar to the thinness and elasticity of viscose-bonded casings, without the environmental problems associated therewith. The non-viscose bonding agent will result in significantly less shrinkage in the base web than results from viscose bonding.
    Type: Grant
    Filed: January 11, 1994
    Date of Patent: May 30, 1995
    Assignee: The Dexter Corporation
    Inventors: Diane M. Robertson, Patrick G. Fay, Ludmila Byalik, Ronald H. Pomeroy

  • Bonded fibrous sheet material
    Patent number: 5108546
    Abstract: A bonded fibrous sheet material for use in the manufacture of food casings having fibrous base web containing a 10% weight or less bonding system and the bonding system having a composition which includes polyvinyl alcohol (degree of hydrolysis of greater than 95%).
    Type: Grant
    Filed: September 10, 1990

  • Fibrous base web bonding system and method
    Patent number: 5063104
    Abstract: A bonded porous sheet material for use in the manufacture of food casing, said material being produced by treating a fibrous web with a thermoplastic film forming material which bonds the fibers of the web and imparts high alkaline strength to the treated wet and subsequently treating the bonded fiber web with a solution of film forming material and an insolubilizing agent for the film forming material.
