The present invention is directed to products, such as paper and paperboard products, comprising a substrate containing cellulose and top ply comprising microfibrillated cellulose and inorganic particulate, to methods of making such paper and paperboard products, and associated uses of such paper and paperboard products. The microfibrillated cellulose and inorganic particulate material are applied at the stage when the wet substrate is in the process of being formed on the wire of a papermaking machine, thereby avoiding the additional cost of more extensive equipment and machinery as well as in separate drying of a coating. The microfibrillated cellulose facilitates the application of inorganic particulate onto the surface of a wet paper or paperboard substrate when applied thusly, by trapping the inorganic particulate on the surface of the substrate and by giving the composite sufficient strength and a suitable pore structure to make it suitable for printing and other end-use demands.

Method of making paper or board products

The present invention is directed to products, such as paper and paperboard products, comprising a substrate containing a recycled cellulose-containing material and top ply comprising one or more inorganic particulate material; to methods of making such paper and paperboard products, and associated uses of such paper and paperboard products. The microfibrillated cellulose and inorganic particulate material are applied at a stage when the substrate comprising a wet web of pulp is in the process of being formed on the wire of a papermaking machine, thereby avoiding the additional cost of more extensive equipment and machinery as well as in separate drying of a coating. The microfibrillated cellulose facilitates the application of inorganic particulate onto the surface of a wet paper or paperboard substrate.

Process of making paper and paperboard products

Fibres and nonwoven materials comprising microfibrillated cellulose, and optionally inorganic particulate material and/or additional additives, and optionally a water soluble or dispersible polymer. Nonwoven materials made from fibres comprising microfibrillated cellulose, and optionally inorganic particulate material and/or a water soluble or dispersible polymer.

Compositions comprising microfibrillated cellulose and polymers and methods of manufacturing fibres and nonwoven materials therefrom

A composition for addition to a ceiling tile, flooring product, or other construction product may include microfibrillated cellulose and optionally an inorganic particulate material. The ceiling tile, flooring product, or other construction product may further include perlite, mineral wool, wood pulp, starch and other additives, where the wood pulp and other inorganic particulate materials are bonded to the microfibrillated cellulose. Methods of manufacturing the compound are also disclosed.

A method for making microcapsules including an encapsulated material may include providing, in an aqueous continuous phase, one or more microcapsules including an encapsulated material surrounded by an inner shell including a first cross-linked polymer matrix. An outer surface of the inner shell may be hydrophobic. The method may also include adding thereto a polymerizable liquid component and a stabilizing agent, wherein the polymerizable liquid component is immiscible in the aqueous environment. The method may also include forming microcapsules wetted by the polymerizable liquid component. The method may further include polymerizing the polymerizable liquid component forming an outer shell including a second cross-linked polymer matrix formed about the inner shell. The microcapsules may be included in articles and compositions.

A barrier coating composition may include an alcohol-based binder and an inorganic particulate. The barrier coating composition may be used in various ways, including in paper products including the barrier composition, methods of preparing the paper products, articles, particularly food grade packaging formed from the paper products, and packaged products, particularly packaged foodstuffs including the packaging.

Coating composition

The present invention describes clear coating compositions comprising a particulate inorganic mineral, wherein the dof the particulate inorganic mineral is less than about 1 &#x3bc;m, and wherein the mineral includes a kandite clay.

A tool for use in wellbore drilling that is suitable for use with a drill string for drilling a wellbore having an inner wall. The tool comprises a cylindrical abrasion surface for contacting the inner-wall and generating particles of solid material, and a smearing device coupled with the drill string for applying radial and circumferential force to smear the generated particles onto the inner wall of the wellbore.

Apparatus and method for improvements in wellbore drilling

The invention concerns a system or a method for maintaining zonal isolation in a wellbore. According to the invention, the system comprises, at a specific location along said wellbore, a sealing element, said sealing element being able to deform both during and after placement and is maintained after placement under compression through a pressurizing fluid or by confinement in a volume.
