Abstract: A delaminated stratified paper towel includes a dense first layer of chemical fiber blend and a second layer of a bulky anfractuous fiber blend unitary with the first layer. The first and second layers enhance a rate of absorption and water holding capacity of the paper towel. In a preferred embodiment, the second layer is a fiber blend having a high bulk softwood fiber and a chemi-thermomechanical pulp. A method of forming a delaminated stratified web of paper towel material includes supplying a first furnish directly to a wire and supplying a second furnish of a bulky anfractuous fiber blend directly onto the first furnish disposed on the wire. Drying the first and second furnishes forms a web of paper towel material having a predetermined dryness. The web of paper towel material is thereafter creped off of the drying device and embossed to a predetermined emboss depth. The web of paper towel material has an enhanced rate of absorption and water holding capacity.

Abstract: A carton and blank for forming the same are disclosed and includes a bottom panel, a top panel, side walls extending substantially perpendicularly away from the bottom panel toward the top panel with the side walls being connected to the bottom panel about a periphery thereof, and overlapping side walls extending substantially perpendicularly away from the top panel toward the bottom panel from predetermined peripheral edges of the top panel. An opening device is formed in the top panel for permitting access to an interior of the carton with the opening device including an opening force receiving mechanism in the form of a lifting tab is integrally formed in one of the overlapping side walls of the top panel for providing an initiation point for the opening device.

Abstract: A system and process for sizing wood chips to provide a flow of wood chips which are acceptable for feeding to a digester of a pulping system. A flow management screen station is provided which divides an incoming unacceptable flow into two fractional flows, neither of which is acceptable for feeding to the digester. One of the output flows from the flow management screen is concentrated in oversized and overthick chips compared to the incoming flow. The other output flow is concentrated in undersized chips and particles compared to the incoming flow. The output flows from the flow management screen are then fed to second and third screening stations which separate "overs" from the respective flows to provide acceptable flows to the digester.

Abstract: A fibrous web having an enhanced capacity for water absorption is produced by impregnating an absorbent fabric with a polymer or copolymer capable of forming by cross-linking an absorbent polymer or copolymer and subsequently heating the treated fabric effecting cross-linking of the polymer to form an absorbent polymer. The product may comprise a non-woven fibrous web or mat having a water-insoluble binder on one surface and a cross-linked hydrophilic polymer or copolymer on its opposite surface.

Abstract: An apparatus is disclosed for the production of a multi-ply sheet product in which separate non-woven fibrous webs are combined into a multi-ply sheet before embossment, embossed as a multi-ply sheet, the embossed webs separated from one another and longitudinally displaced realtive to one another, and then recombined into an embossed multi-ply sheet with the embossments out of register with one another. The resulting product exhibits enhanced softness and absorbence as compared with similar products comprising simultaneously embossed multi-ply webs.

Abstract: A substantially farinaceous, fiber-containing batter to produce a battered and fried food having reduced lipid retention and increased moisture content after frying. The preferred fibrous additive for this purpose is powdered cellulose; however, various dietary fibers such as oat fiber, soy fiber, pea fiber, or sugar beet fiber, to name only a few, may be used to achieve the same purpose. More specifically, the fibrous additive is preferably present in the batter in an amount of about 0.3-3.0% by weight of the batter having an average fiber length of from about 50-500 microns. The addition of fiber to a batter used for frying will allow food producers to provide a healthier fried food item which will be more appealing to a health conscious consumer. Moreover, the fiber additive can also enhance the appearance of the fried food by providing a golden yellow color after frying, rather than a non-uniform brown color containing brown and black batter particles.

Abstract: A microwave interactive coating composition and microwave reactive paper and paperboard heaters comprising the coating composition are disclosed.
