Abstract: The present invention relates to a process for the manufacturing of composite materials from natural fibers and thermoplastic polymers. Examples of fibers are wood fibers originating from pulping processes known as refiner pulp (RMP),thermomechanical pulp (TMP) or chemi-thermomechanical pulp (CTMP),but the process can also be applied to other kinds of natural fiber containing raw materials. In the process according to the present invention, fibers are introduced from the blowline or the housing of a refiner into a flash tube dryer, separated from humid air in a cyclone, introduced into a compounder and mixed with at least one thermoplastic polymer and the product is subsequently pelletized. The process according to the present invention is advantageously run as a continuous process.

Abstract: The present disclosure relates to a blank to be inserted in a package for providing thermal insulation and/or shock-absorbing properties. The blank comprises a first set of panels being foldably interconnected and a second set of panels being foldably connected to preferably one of the panels, of the first set of panels. At least two of the panels of the first set of panels are foldably connected along a groove having a depth and a width. The depth of the groove is greater than the width such that, as a first panel is folded relative to a second panel a groove edge portion of the first major surface on the first panel extends into the groove and abuts a side wall of the groove formed on the second panel. The present disclosure also relates to a package having insulation and/or shock-absorbing properties and a method for providing a package.

Abstract: A method for manufacturing a disposable item (10) comprises moistening (S1, S11) at least a portion of a pulp sheet (110) or multiple pulp sheets (210, 220, 230, 310, 320) with an aqueous solution, emulsion, dispersion and/or suspension to reduce a stiffness of the pulp sheet(s) (110, 210, 220, 230, 310, 320). The method comprises providing (S2, S12), after the moistening step (S1, S11), a blank (100, 200, 300) comprising the pulp sheet (110) or the multiple pulp sheets (210, 220, 230, 310, 320) superimposed onto each other. The blank (100, 200, 300) has an average moisture content selected within a range of from 15 up to 60 weight-%. The method also comprises cold pressing (S3, S13) the blank (100, 200, 300) between matched molds defining a 3D shape of a precursor of the disposable item (10) in the blank (100, 200, 300) to remove water from the blank (100, 200, 300) and hot pressing (S4, S14) the precursor in the blank (100, 200, 300) between heated matched molds defining a 3D shape of the disposable item (10) to remove water from the blank (100, 200, 300) and form the disposable item (10). The disposable item (10) is cut out (S5, S14) simultaneously with or after hot pressing (S4, S14) the blank (100, 200, 300).

Abstract: A folded 3D shaped packaging product (30) is folded at at least one crease (22A, 22B, 22C, 22D, 22E) constituting a folding line in a 3D shaped product (20) formed by hot pressing of an air-laid blank (10) comprising natural fibers at a concentration of at least 70 % by weight of the air-laid blank (10) and a thermoplastic polymer binder at a concentration selected within an interval of from 4 up to 30 % by weight of the air-laid blank (10). The folded 3D shaped packaging product (30) is useful for cushioning and/or thermal insulation of packaged goods and can protect multiple sides of the packaged goods.

Abstract: An air-laid blank (10) comprises natural fibers at a concentration of at least 70 % by weight of the air-laid blank (10) and a thermoplastic polymer binder at a concentration selected within an interval of from 2.5 up to 30 % by weight of the air-laid blank (10). The air-laid blank (10) has an average density and a portion (11) of the air-laid blank (10) has a density different from the average density. The air-laid blank (10) is produced by modifying the air-permeability of a portion (121) of an air-permeable collector (120) to form a portion (11) of the air-laid blank (10) having a density from the average density.
