  • the present invention has for its object to obviate or at least reduce the above stated problems in conventional packaging units.
  • the present invention provides for this purpose a method for manufacturing a packaging unit made of moulded pulp for products like eggs according to claim 1.
  • mouldable pulp that is used for the forming of the packaging unit in a manufacturing process comprises a foamed mouldable fiber material having a fiber material and a foaming agent.
  • the fiber material may relate to conventional mouldable pulp material originating from recycled paper, for example, and that is foamed with the aid of the foaming agent.
  • This provides a foamed mouldable pulp that can be used for forming the packaging unit according to the invention in the manufacturing process.
  • the solid content of the fiber material in the packaging unit according to the invention is above 35% by weight. Therefore, the solid content of the fiber material in de final product after drying is even higher, and certainly above this 35% by weight.
  • the moulded pulp may comprise additional components, such as wet strength agent, dry strength agent, dye/pigment, starch derivatives, releasing agents such as calcium stearate.
  • the quality of the resulting packaging unit has even improved as compared to conventional packaging units.
  • the weight of the product in relation to its strength is improved.
  • the packaging unit is more homogeneous and a significant decrease in roughness is achieved as compared to conventional packaging units. This improves the haptic appearance of the packaging unit obtained by the method according to the present invention.
  • the visual appearance of the packaging unit is further improved as will be appreciated by the consumers.
  • a packaging unit made of moulded pulp a full fiber packaging unit is achieved.
  • Such full fiber packaging unit can be recycled favourably.
  • the packaging unit obtained by the method according to the present invention is preferably provided free of additional labels, additives and/or chemical substances. This achieves a significant effect on the sustainability.
  • a packaging unit made from foamed moulded fiber material may decompose more effectively and also in that respect contributes to a more sustainable product as compared to conventional packaging units.
  • a similar strength of the packaging unit can be achieved with less weight, and, therefore, less raw material is required.
  • This raw material involves recycled paper, for example. This means that from a given amount of raw material more packaging units can be produced and/or stronger packaging units can be manufactured from the same amount of raw material. This results in a more effective manufacturing process.
  • packaging units having a smaller stacking pitch such that a stack of packaging units may consist of a higher number of packaging units according to the invention as compared to a stack of packaging units having a conventional design. This improves the handling of packaging units.
  • the improved strength of the packaging unit from foamed moulded fiber material enables other shapes or designs for the packaging unit obtained by the method according to the present invention as for conventional packaging units would be possible. This improves the overall flexibility and freedom in the design of packaging units.
  • the reduction of the roughness of the packaging unit from foamed moulded fiber material may improve the printing possibilities for the packaging unit. This may obviate the need for providing separate labels. This simplifies the manufacturing process of the packaging units and/or reduces the amount of required material for a packaging unit.
  • the foamed mould fiber of the packaging unit can be produced with improved heat insulation as one of the characteristics, thereby improving protecting/insulating the products in the packaging unit against (varying) outside conditions. This improves keeping products in the packaging unit according to the present invention.
  • the solid content of the fiber material after forming is above 36% by weight, preferably above 37% by weight, more preferably above 38% by weight, and most preferably above 39% by weight. It is shown that with the use of a foamed mouldable fiber pulp in the manufacturing process a higher solid content of the fiber material in the packaging unit after forming can be achieved, above 35% by weight and even higher. This significantly reduces the requirements for the drying operation as described above.
  • the foamed mould fiber material comprises a volume percentage of more than 50% air, preferably more than 60%, and is most preferably in the range of 60-75%.

  • the material comprises natural fibers of non-wood lignocellulosic biomass.
  • lignocellulosic biomass By providing lignocellulosic biomass from other resources as the conventional paper recycling, an alternative source for the material for the packaging unit of moulded pulp is provided. This improves the availability of raw (starting) material when manufacturing packaging units according to the invention. In addition, the use of this biomass provides additional visual effects that may provide the packaging unit with a more natural feel, and, in addition, may improve the sustainability of the packaging unit according to the present invention.
  • the moulded pulp may comprise at least 10% by weight non-wood lignocellulosic biomass, preferably at least 50% by weight, more preferably at least 80% by weight, even more preferably at least 85% by weight, and most preferably at least 92.5% by weight non-wood lignocellulosic biomass.
  • the lignocellulosic biomass comprises biomass originating from plants of the family of Poaceae Family including grass type of plants, including grass and barley, Mos, rise, weed, oaths, rye, weed grass, bamboo, sugar cane, grape seeds, other cereals, etcetera.

  • the combination of using this biomass raw material in combination with, or as an alternative to, moulded pulp originating from paper and/or paperboard provides further possibilities for the use of different raw materials, and improves the "green" sustainable appearance of the resulting packaging units. Foaming such alternative (non-wood) fiber material provides similar effects and advantages as described for the (recycled) paper material.
