| 20080314536 | High Quality Paperboard and Products Made Thereof - The invention relates to a high quality paperboard comprising at least two plies, a first ply having good surface properties and strength, and a second ply for providing the paperboard with bulk wherein the second ply comprises hardwood CTMP. This paperboard has an internal strength and a bending resistance that is comparable with conventional high quality paperboard based on softwood CTMP. The invention also relates to products manufactured of the paperboard. | 12-25-2008 |
| 20090114359 | Method For Use In The Wet End Of A Paper Machine, Cardboard Machine Or An Equivalent Web Forming Machine - The invention relates to a method in the wet end of a web forming process. In the method, at least one electrode pair ( | 05-07-2009 |
| 20090186135 | HEAT-SEALED STERILISED PRODUCT PACKAGE, PACKAGING MATERIAL FOR THE SAME AND USE OF THE PACKAGING MATERIAL - The invention relates to a polymer-coated heat-sealable packaging material, to a heat-sterilised package formed from this and to the use of the packaging material. The material comprises a fibre base | 07-23-2009 |
| 20100015460 | METHOD FOR CONTROLLING SURFACE CONTACT AREA OF A PAPER OR BOARD SUBSTRATE - The application relates to a method for controlling contact area of a paper or board substrate ( | 01-21-2010 |
| 20110000847 | METHOD FOR PRODUCING PARTICLES ELECTROSTATICALLY - The invention refers to a method for forming particles or droplets of at least one substance comprising the steps of providing a foamed medium, which foamed medium comprises said substance, and forming particles or droplets of said substance at least partly by electrostatic processing. The use of foamed medium in electrostatic processing enables higher production speeds and increases the evenness of a coating layer formed by electrospinning or electrospraying the particles or droplets on a substrate. | 01-06-2011 |
| 20110031156 | SOLVENT-RESISTANT LIQUID PACKAGING BOARD, ITS MANUFACTURING METHOD AND USE, AND A DRINKING CUP MADE OF THE SAME - The invention relates to a polymer-coated, heat-sealable liquid packaging board that resists solvents, such as strong alcoholic drinks, to a method of manufacturing the same and to a drinking cup made of the same. In the invention, resistance to solvents is achieved by lowering the raw edge penetration to the board. For this, the fibre base of the board contains at least 1.3 kg of hydrophobic size containing alkyl ketene dimer (AKD) per 1 tonne of dry matter, and at least 1.0 kg of wet-strength size per 1 tonne of dry matter, the density of the fibre base is 630-800 kg/m3 and the amount of heat-sealable polymer in the top layer is higher than the Bristow wheel roughness volume of the uncoated fibre base and/or at least 14 g/m2. When manufacturing the board, the AKD size, the length of the carbon chain of which is preferably at least C18, and the wet-strength size, such as polyamidoamine epichlorohydrin resin (PAAE), are added into the stock on the wire of the paper or board machine or before the same. At the same time, the pH of the tail water is adjusted so as to be alkaline, preferably to a value of over 9, whereby the pH of the water extract of the obtained board is in the order of about 7 or more. The drinking cup made of the board resists an ethanol solution of 30% by weight at 23° C. for at least 1 h. | 02-10-2011 |
