Abstract: The invention relates to use of polylactide (PLA) as an extruded polymer coating on paper or board intended for the production of containers and packages, which are heated in a stove or microwave oven. According to the invention a polyfunctional cross-linking agent, such as trialkyl isocyanureate (TAIC), is blended with PLA, and the extruded coating layer is subjected to cross-linking electron beam (EB) radiation. PLA may be used as such or blended with another biodegradable polyester such as polybutylene succinate (PBS). EB radiation has been found to improve adhesion of the coating to the paper or board substrate, heat-scalability of the coating, and heat-resistance of the finished containers and packages.

Abstract: The invention relates to methods for lowering the melt viscosity and thereby improving heat-sealability of a polyester. The invention also relates to a method for manufacturing a heat-sealed container or package from fibrous-based, polyester-coated packaging material, and a method for heat-sealing polyester. The solution according to the invention is subjecting polyester to electron beam (EB) radiation. The lowered melt viscosity allows a lower heat-sealing temperature, and permits sealing of polyester to an uncoated fibrous surface. The preferred polyester for the invention is polylactide, as such or as blended with another polyester.

Abstract: The present invention discloses a high quality multi-ply paperboard. The invention is characterized in that the middle ply of the paperboard comprises at least 50 % of high -temperature chemithermomechanical pulp (HT-CTMP) from hardwood fibers, calculated on the total fiber weight of said middle ply. It has surprisingly been shown that the use of HT-CTMP from hardwood fibers in the middle ply enables the production of a paperboard with a very high bulk and with maintained strength properties. Moreover, the use of HT-CTMP from hardwood fibers significantly improves the brightness properties and the formation of the paperboard.

Abstract: The invention relates to a method and an apparatus for deep-drawing a tray (1) from fiber-based sheet material (2), such as polymer coated board. The apparatus comprises a female moulding tool (3), which comprises a cavity (7) for forming the tray bottom outwardly, a male moulding tool (4), which comprises a plunger plate (11) for forming the tray bottom inwardly, the plunger plate being movable with respect to the cavity for forming the tray, and clamps (6, 15) with an interface for holding the sheet material and forming a tray rim flange. According to the invention by laterally distancing at least one of the moulding tools (3, 4) from the sheet material leeway is provided for free forming of the tray side walls while wrinkling or tearing of the same is avoided. Spacer plates (13) may be positioned behind the plunger plate (11), to adjust its position in relation to the cavity (7) of the female moulding tool (3). The cavity may have a separate bottom plate (8) and spacer plates (9) there below, or screw means may be provided for adjusting the distance of the bottom of the cavity from the clamp interface and thereby varying the depth of the tray.

Abstract: The invention discloses a multi-ply paperboard comprising pulp of cellulosic fibers, wherein 100% of the total fiber content of said paperboard are hardwood fibers. Contrary to prevailing assumptions, it has surprisingly been found that it is possible to produce a multi-ply paperboard of 100% hardwood pulp with a comparable strength, a higher bulk and a higher bending resistance as compared to a multi-ply paperboard comprising softwood pulp.The use of 100% hardwood pulp is economically favorable, since the access to softwood pulp is limited in large parts of the world. Moreover, a high amount of hardwood pulp in the paperboard improves the surface properties and the optical properties of the board.

Abstract: The present invention discloses a multi-ply paperboard for packaging of liquid and/or food products, which paperboard comprises a top ply, a back ply and at least one middle ply arranged between said top and back ply. The invention is characterized in that the back ply is made of unbleached hardwood pulp to 100% by weight, calculated on the total fiber weight of said back ply. It has surprisingly been found that the use of unbleached pulp in the back ply makes it possible to use 100% hardwood fibers in the back ply, calculated on the total fiber weight of the back ply, and still achieve a high quality board with an acceptable strength and bending resistance.
