Patent number: 7740740Abstract: The invention provides a low density paperboard material and associated method for use in producing an insulated container, and is especially well-suited for making cups. The paperboard material comprises a paperboard web including wood fibers and expanded microspheres, and has a relatively low density ranging from about 6 to about 10 lb/3 MSF/mil, a relatively high caliper ranging from about 24 to about 35 mil, and an internal bond strength of at least about 80×10?3 ft-lbf., preferably at least 100×10?3 lft-lbf. For applications such as cups the material is also coated on one or both sides with a barrier coating, preferably low density polyethylene, to limit liquid penetration into the web. The low density paperboard material of the invention is convertible for manufacture of containers, particularly cups, and exhibits insulative properties comparable to higher cost materials conventionally used to make cups.Type: GrantFiled: September 27, 2007Date of Patent: June 22, 2010Assignee: International Paper CompanyInventors: Kosaraju Krishna Mohan, Alexander A Koukoulas, Peter Matthew Froass, David Verd Reed

Patent number: 7732388Abstract: Lubricant formulations comprising a phospholipids such as lecithins and a low hydrophobic lipophilic balance (HLB) surfactant provide improved rheological properties for coating a rapidly moving web, such as a paper web. The low hydrophobic lipophilic balance (HLB) surfactant is preferably an alcohol ethoxylate having an HLB value of between 7 and 10 or more preferably between 7.5 and 9.5. The lubricant formulations of the invention are preferably applied to the paper web as part of a coating mixture. The lubricant is well-suited for short-dwell coating methods.Type: GrantFiled: January 10, 2006Date of Patent: June 8, 2010Assignee: Bercen IncorporatedInventor: Ray Peltier

Patent number: 7732043Abstract: A ceiling tile product and method in which a slurry formed mat primarily comprising mineral wool and binder is provided with a binder enhancement zone at its face. The binder enhancement zone can reduce the total required latex content, reduce the amount of finish or paint needed to achieve a commercially acceptable color and improve noise reduction.Type: GrantFiled: September 15, 2005Date of Patent: June 8, 2010Assignee: USG Interiors, Inc.Inventors: Mirza A. Baig, William A. Schmitt

Patent number: 7708861Abstract: An anti-blocking composition including about 75% to about 99% weight percent a metal salt of stearate and about 1% to about 25% weight percent stearic acid is provided. In addition, an anti-blocking composition including about 90% to about 99.5% a metal salt of stearate and about 0.5% to about 10% fiber is provided. The anti-blocking compositions may be formed into blocks and applied to a web of paper to reduce adherent properties of the paper. Further, a method of improving the handling properties of paper cut from a web is provided. The method includes the steps of coating a surface of a web of paper with an effective amount of a coating composition of the present disclosure, and cutting the web into sheets of paper.Type: GrantFiled: January 16, 2007Date of Patent: May 4, 2010Assignee: RR DonnelleyInventors: Kevin J. Hook, Henderikus A. Haan, Myron C. Heeb

Patent number: 7699960Abstract: Methods for producing cast-coated papers showing a reduced level of curling and reduced curling or wavy deformation caused by moisture absorption or other reasons as well as showing a high surface quality in the cast-coated surface. The steps for producing cast-coated papers include applying a coating color based on a pigment and an adhesive on one side of a base paper, and pressing/drying the coated layer in the wet state against a casting drum mirror surface, where moisture is added to the coated paper by passing it through conditioned air at a high temperature and a high humidity (for 20 seconds or more) after pressing/drying the coated layer against a casting drum.Type: GrantFiled: March 31, 2004Date of Patent: April 20, 2010Assignee: Nippon Paper Industries Co., Ltd.Inventors: Katsumasa Ono, Hidenobu Todoroki, Yuji Abe
