The resulting product enjoys significantly improved dimensionally stability when exposed to water. Thickness swelling of the coated product is reduced by over 70% as compared to a conventional composite cellulosic product without the coating. In the case of oriented strand board (OSB) manufactured according to the method of the present invention, thickness swell of 2-5% after 24 hour water soaking is observed as compared to 10-15% swell with conventional OSB.Type: ApplicationFiled: February 14, 2001Publication date: October 24, 2002Inventors: Chunping Dai, Peter Ens

Publication number: 20020150704Abstract: 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.Type: ApplicationFiled: January 29, 2002Publication date: October 17, 2002Inventors: Eric Baer, P.

Publication number: 20020136912Abstract: Optical brighteners are widely used for decreasing the apparent yellowness of polymeric materials. Polyethylene, as a coating film for photographic paper has presented unique problems because of its general lack of compatibility with conventional, large, fluorescent brightener molecules. The present invention provides a solution to this problem by incorporating into the polyethylene an optical brightener compatibilizing amount of a second polyolefin having alkyl groups pendant from the polymer backbone which serves to reduce the exudation of the optical brightener in articles or substrates comprised of or coated with such compositions.Type: ApplicationFiled: November 12, 1999Publication date: September 26, 2002Inventor: GETHER IRICK
