    摘要： The invention relates to the packaging sector of food products for human consumption. More specifically, the invention relates to a production process for a food tray which is particularly (but not exclusively) suitable for use in controlled atmosphere packaging, and to the tray thus obtained. Said production process for a cardboard food tray (1) comprises the phases of: - providing a sheet (2) of cardboard, where said cardboard is corrugated; - applying a thermo-adhesive substance to areas of said sheet; - die-cutting and creating creases (3) on said sheet (2); - folding said die-cut sheet (4) along said creases (3) and overlapping flaps of previously adhesivised cardboard and applying a source of heat to reactivate said thermo-adhesive substance, to form a shaped tray (1), comprising a bottom (5), side walls (6) and a perimeter edge flange (7), adapted to define a compartment (8) for containing food; - positioning said tray (1) in succession with other trays (1) already shaped to create a stack (9) of stored trays. Said process also comprises the mechanical pressing of at least said perimeter edge flange (7), so as to crush said corrugated cardboard and flatten said perimeter edge flange (7), making its surface flat even at the flaps of overlapping cardboard.

    摘要： The present disclosure relates to a paperboard packaging container (1) for bulk solids, the container (1) comprising a tubular container body (2) being made by a laminate sheet material. The first end (3) of the container body (2) is curled inwardly providing a first curled edge (14) comprising an edge portion (14a) and an inner portion (14b). To improve the stability and durability of the curled edge, the inner portion (14b) of the first curled edge (14) is provided with three or more indentations (15) being spaced apart along a circumference of the tubular container body (2). The disclosure also relates to a method for forming a paperboard packaging container, and to a curling tool for forming a curled edge.

    摘要： A process is described for realising a container made of a paper material obtained by deformation of an intermediate container (2') having a truncoconical first configuration exhibiting a base (3') and a lateral wall 4' emerging distancingly from the base such as to define a containing cavity (5'); the step of deformation is suitable for bringing a portion of the lateral wall (4') of the intermediate container (2') into the plane containing the base (3') such as to define a final container (2) having a second configuration that is different from the first configuration and in particular substantially cylindrical.

    摘要： A die system (10) for cutting a piece of sheet stock (11) to create a blank and forming the blank to create a container includes first and second mating die halves (56, 96) and a cutting punch (68). The first and second mating die halves (56, 96) are configured to move together to form the container from the blank. The cutting punch (68) extends about the first die half (56) and is movable therewith. The cutting punch (68) is configured to cut the piece of sheet stock (11) to create the blank. Movement of the die halves (56, 96) together causes the cutting punch (68) to cut the blank from the piece of sheet stock (11) and further movement of the die halves (56, 96) together causes the first and second die halves (56, 96) to form the container from the blank.

    摘要： A 3D shaped product (20) is 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 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. The 3D shaped product (20) is recyclable in a repulping process. At least a part of the thermoplastic polymer binder is water soluble at a repulping temperature of the repulping process. The 3D shaped product (20) are environmentally friendly alternatives to plastic 3D shaped products made by foamed polymers and can be recycled in existing recycling schemes.
