  • Cellulose material containing barrier film structures
    Patent number: 5604042
    Abstract: A polymeric film structure having improved oxygen, flavor/odor, grease/oil and moisture barrier characteristics is disclosed. The structure includes a polymeric substrate adapted to receive an oxygen barrier on one side thereof and a moisture barrier on the other side of the oxygen barrier. The oxygen barrier includes polyvinyl alcohol cross-linked with aldehyde containing cross-linking agents in the presence of a catalytic amount of sulfuric acid. The moisture barrier can be provided by the carrier web or incorporated into the cellulosic material, which is preferably box board.
    Type: Grant
    Filed: December 19, 1995
    Date of Patent: February 18, 1997
    Assignee: Mobil Oil Corporation
    Inventors: Eber C. Bianchini, Anthony R. Knoerzer, Larry A. Parr, Leland W. Reid
  • Oxygen, flavor/odor, grease/oil and moisture barrier film structures
    Patent number: 5512338
    Abstract: A polymeric film structure having improved oxygen, flavor/odor, grease/oil and moisture barrier characteristics is disclosed. The structure includes a polymeric core sandwiched between an oxygen barrier on one side thereof and a moisture barrier on the other side of the polymeric core. The oxygen barrier includes polyvinyl alcohol cross-linked with aldehyde containing cross-linking agents in the presence of a catalytic amount of an inorganic acid, preferably sulfuric acid. The moisture barrier is a coating of polyvinylidene chloride, which also enhances the oxygen barrier of the polymeric film structure.

  • Cross-linked PVOH coatings having enhanced barrier characteristics
    Patent number: 5496649
    Abstract: An improved oxygen barrier layer for coating a substrate, such as a polymeric film. The oxygen barrier is a layer of cross-linked polyvinyl alcohol and glyoxal, which exhibits improved barrier characteristics to the transmission of oxygen. The oxygen barrier is produced by coating a solution of polyvinyl alcohol, glyoxal and tensoactive agent onto at least one side of a substrate adapted for receipt of such solution. The polyvinyl alcohol is thereafter cross-linked in the absence of a catalyst to provide the oxygen barrier.

  • Oxygen and moisture barrier metallized film structure
    Patent number: 5487940
    Abstract: A polymeric film structure having improved oxygen and moisture barrier characteristics is disclosed. The structure includes a polymeric substrate adapted to receive an oxygen barrier on one side thereof and a moisture barrier on the other side of the oxygen barrier. The oxygen barrier includes polyvinyl alcohol cross-linked with aldehyde containing cross-linking agents in the presence of a catalytic amount of an inorganic acid, preferably sulfuric acid. The moisture barrier is a metallized polymeric composite, preferably metallized oriented polypropylene.
