A film and laminated product having said oxygen scavenger composition are also disclosed.Type: GrantFiled: May 30, 2006Date of Patent: November 18, 2008Assignee: Cryovac, Inc.Inventors: Cynthia L. Ebner, Andrew E. Matthews, Terry O. Millwood

Publication number: 20080261019Abstract: The present invention relates to a thermoplastic/natural cellulosic fiber composite, and more specifically to a high molecular weight compatibilizer within that composite resulting in both a high flex strength and high modulus and significant reduction in water absorption. The compatibilizer is preferably a terpolymer comprising: a) 0.5-20 percent by weight of monomer units selected from the group consisting of maleic anhydride, substituted maleic anhydride, mono-ester of maleic anhydride, itaconic anhydride, maleic acid, fumaric acid, crotonic acid, acrylic acid and methacrylic acid; b) 0 to 40 percent by weight of monomer units selected from styrene and functionalized styrene; and c) 40 to 98.5 percent by weight of monomer units selected from the group consisting of C1-8 alkyl acrylates and methacrylates, and vinyl acetate.Type: ApplicationFiled: October 13, 2006Publication date: October 23, 2008Applicant: ARKEMA INC.Inventors: Xianfeng Shen, Thomas Bole, Robert A. Iezzi, Zuzanna Cygan, Rong M. Hu, Barbara L. Stainbrook, Peter A. Callais, Jason S. Ness

Publication number: 20080261021Abstract: The specification pertains to a single or multiple coated printing sheet in particular but not exclusively for sheet-fed offset printing with an image receptive coating layer on a paper substrate. The printing sheet has the property that it can be printed in an offset printing process without spraying a fine powder, usually called offset powder or dust powder, on the sheet as it comes off the press to prevent the ink from transferring to the back side of the next sheet. Also irradiative (UV or IR) drying on the sheet fed press is not necessary and/or the use of overprint varnish is not required. In addition to that, unexpectedly short times until reprinting and converting can be achieved. Furthermore methods for making such a printing sheet and uses of such a printing sheet are disclosed.Type: ApplicationFiled: July 12, 2006Publication date: October 23, 2008Applicant: SAPPI NETHERLANDS SERVICES B.V.Inventors: Jean-Pierre Haenen, Peter Resch, Bert Scholte

Patent number: 7435483Abstract: Disclosed are coated fiber-containing articles, including paper, paperboard, and molded fiber, and methods for preparing such articles. A preferred method comprises heating paperboard containing a polymeric binder to a temperature sufficient to remove at least some moisture from the paperboard; applying an aqueous dispersion or solution of at least one water-dispersible or water-soluble polymer to the paperboard product; heating the paperboard to at least partially cure the water-dispersible or water-soluble polymer; and cooling the paperboard to at least 160° F. to reduce the tackiness of the cured water-dispersible polymer.Type: GrantFiled: April 4, 2002Date of Patent: October 14, 2008Assignee: Advanced Plastics Technologies Luxembourg S.A.Inventors: Robert A. Lee, Gerald A. Hutchinson, Charles P. Klass
