    Abstract: Method (200) for non-contact processing of fibrous material comprising providing (206) a blank of fibrous material, providing (204) a laser processing equipment, said equipment being configured to exhibit a laser emission substantially at a wavelength falling within a range from 120 about 2 to about 10.4 10.3 microns, and subjecting (210, 210A, 210B) the blank to a laser beam of the laser processing equipment to produce a target design therefrom, incorporating directing the beam to the blank following a selected pattern in accordance with the target design. Arrangement (100) for implementing the method is presented.

    Abstract: The invention relates to a method of manufacturing a heat-sealable packaging material, the method comprising the steps of: providing a paperboard substrate comprising a top ply, applying a first dispersion barrier layer on the top ply, wherein the first dispersion barrier layer comprises a latex having a first glass transition temperature, and applying a second dispersion barrier layer on the first barrier layer, wherein the second dispersion barrier layer comprises a latex having a second glass transition temperature, wherein the second glass transition temperature is higher than the first glass transition temperature, wherein the grammage of the second dispersion barrier layer is lower than the grammage of the first dispersion barrier layer, and wherein the second dispersion barrier layer comprises pigments. The invention further relates to a respective heat-sealable packaging material.

    Abstract: Method for making a film that comprises microfibrillated cellulose, wherein the film has low OTR values and especially suitable for a tropical environment. The method comprising the steps of providing a suspension comprising microfibrillated cellulose (MFC), forming a film from said suspension, wherein the film having a solid content above 40%, preferably above 50%, treating the film with flame or plasma treatment, such that a surface activation takes place on the film, and cooling the film, wherein the surface of the film having a decreased OTR value and a high moisture resistance.

    Abstract: The present invention relates to a method for manufacturing microfibrillated polysaccharide, preferably microfibrillated cellulose. The invention also relates to microfibrillated cellulose obtainable by the method and use of the microfibrillated cellulose. The method of manufacturing microfibrillated cellulose comprises the following steps: a) Providing a hemicellulose containing pulp, b) Providing wood degrading enzymes c) Mixing pulp and enzymes d) Keeping the mixture in a continuous, flowing system of essentially cylindrical geometry (for example in a plug-flow reactor), e) Conveying the mixture to one or more mixing zones for recirculating and homogenizing the mixture, and f) Harvesting microfibrillated cellulose with a relatively narrow size distribution during the recirculation.

    IPC: B31B50/44

    Abstract: A deep-drawn paper tray made of paper material, a method and an apparatus for manufacturing the tray, and a closed product package comprising the tray. The tray having a bottom and upwardly expanding side walls around the bottom, the side walls of the tray being shaped to expand through a plurality of circumferential steps dimensioned low enough for obtaining wrinkle-free side walls for the tray. The outermost step is a flat, wrinkle-free rim flange, which enables liquid and gas proof heat-sealing of a lid to form the package. The apparatus may comprise upper and lower moulding tools with concentric movable frames for forming the tray bottom and side wall steps from paper blanks, and moulding tools may be mounted onto a rotating turret carrying a paper blank through working stations arranged along the turret circumference, to shape the tray bottom and the side wall steps at the consecutive stations.
