The material comprises a fibre base | 07-23-2009 |
20090258119 | POLYMER-COATED LIQUID PACKAGING BOARD, A PACKAGE FORMED FROM IT AND THE USE OF THE POLYMER - The object of the invention is a liquid packaging board ( | 10-15-2009 |
20090298662 | Method for protecting the untrimmed edge of a paperboard or paper - The invention relates to a method for protecting the untrimmed edge of paperboard or paper ( | 12-03-2009 |
20090324861 | POLYMER-COATED HEAT-SEALABLE PACKAGING MATERIAL AND A SEALED PACKAGE MANUFACTURED THEREOF - The invention relates to a heat-sealable packaging material and a sealed package formed from the same, especially for packaging foodstuffs. The packaging material comprises a base layer of paper or board and polymeric heat-sealable layers on one side of the base layer or, preferably, on both sides thereof. According to the invention, at least two layers of ethylene vinyl alcohol copolymer (EVOH) with different fractions of ethylene monomer are arranged on the packaging material to provide an oxygen barrier. The layers can locate against each other without a tie layer between them. The heat-sealable polymer can be a polyolefin, and, in addition, other polymeric barrier layers can be incorporated into the material to improve its oxygen, fat and aroma tightness. | 12-31-2009 |
20100084299 | COVER OF A PACKAGE, A METHOD FOR MANUFACTURING THE SAME AND A PACKAGE SEALED WITH A COVER AND A METHOD FOR SEALING A PACKAGE - A cardboard cover that seals a package and that also enables the resealing of the package. The lower surface of the cover ( | 04-08-2010 |
20100112247 | BOARD, A METHOD OF MANUFACTURING THE SAME AND A CONTAINER MADE FROM IT - The invention relates to a method of manufacturing board ( | 05-06-2010 |
20120097352 | TREATMENT OF FIBRES TO ENDURE PROCESSING - The invention relates to a method of treating chemical pulp fibres by a polymerizing hydroxy acid, the fibres thus obtained and the products refined from them. In the method, the hydroxy acid reacts with the reactive groups of the fibres in the presence of a catalyst, forming ester bonds. The following units of the same hydroxy acid are oligomerized and/or polymerized to these grafted acid residues. The fibres thus treated and the products refined thereof endure better processing stages that include drawing and stretching than untreated fibres. | 04-26-2012 |
20130071677 | HEAT-SEALABLE BIODEGRADABLE PACKAGING MATERIAL, A METHOD FOR ITS MANUFACTURE, AND A PRODUCT PACKAGE MADE FROM THE MATERIAL - A heat-sealable biodegradable packaging material, its manufacturing method and a product package formed thereof, where the packaging material comprises a fiber substrate, an inner polymeric coating layer against the fiber substrate, which contains polylactide and a biodegradable polyester that is blended therewith to improve the adhesion between the inner coating layer and the fiber substrate, and an outer coating layer that constitutes the outer surface of the material and contains polylactide and a biodegradable polyester that is blended therewith to improve the heat sealing ability of the layer, the portion of polylactide in the inner layer than that in the outer layer. The inner and/or outer coating layers can further have blended therewith a small amount of acrylic copolymer that improves the adhesion and/or heat sealing ability. The coating layers can be introduced onto the fiber substrate by extrusion or coextrusion. | 03-21-2013 |
20130137562 | METHOD FOR IMPROVING THE HEAT SEALABILITY OF PACKAGING MATERIAL AND METHOD FOR MANUFACTURING HEAT-SEALED CONTAINER OR PACKAGE - A method for improving the heat sealability of a packaging material and a method for manufacturing a heat-sealed container or package are described. The material can be polymer-coated packaging paper or cardboard, or a polymeric packaging film. The material includes a polymer layer that contains polyester, particularly polylactide, the heat sealability of which is improved by ultraviolet radiation. Polylactide is useful as such or when blended, for example, with other biodegradable polyester. The containers and packages thus manufactured include disposable drinking cups and cardboard carton and box packages. | 05-30-2013 |
20130165721 | CATALYTIC REFINING OF TERPENES OF PULP ORIGIN - Biobased p-cymene and methods of producing same, which can further be converted to terephtalate. Further, a method is described for converting crude sulfate turpentine recovered from chemical wood pulping into p-cymene and eventually to terephtalic acid of biological origin, and and products thereof respectively. In said method, both conversion and desulfurization is realized in one reaction step. The disclosure is also related to use of zeolite catalysts in said method. | 06-27-2013 |
20130178650 | HYDROGEN TREATMENT OF IMPURE TALL OIL FOR THE PRODUCTION OF AROMATIC MONOMERS - A method of manufacturing aromatic hydrocarbons, which are suitable for the production of terephthalic acid, from tall oil-based raw material. According to the invention, the raw material that contains tall oil or its fraction is catalytically deoxygenated with hydrogen, and one or more aromatic hydrocarbons that can be converted into terephthalic acid are separated from the deoxygenated reaction yield. The deoxygenation catalyst is a NiMo catalyst and, in addition, a cracking catalyst can be used, such as an acidic zeolite catalyst. The separated hydrocarbon can be p-xylene, o-xylene or p-cymene. According to the invention, these can be converted by oxidation and, when needed, by a re-arrangement reaction into terephthalic acid that is suitable for the source material of the manufacture of bio-based polyethylene terephthalate. | 07-11-2013 |
