Definitions

  • the invention relates to a method for producing an insulating packaging, an insulating packaging, a system for producing an insulating packaging and a packaging box with an insulating packaging.
  • Insulating packaging made of foamed polystyrene (EPS) is known from the prior art, which enables mobile cooling of products.
  • the products to be cooled are placed in a container, usually a square box made of EPS, together with a cooling medium, such as ice packs or dry ice, and closed with a removable EPS lid.
  • a cooling medium such as ice packs or dry ice
  • the EPS box with the lid closed can be placed in a shipping box and shipped.
  • the invention is based on the object of enabling the production and use of insulating packaging with a high degree of efficiency and effectiveness.
  • a method for producing an insulating packaging comprising the following steps: providing cellulose fibers; Portioning the cellulose fibers into a cellulose fiber bundle with cellulose fibers; loosening the cellulose fiber bundle; Introducing the cellulose fibers of the cellulose fiber bundle a wrapping material; flat compaction of the cellulose fibers of the cellulose fiber bundle within the casing material to form a fiber carpet (16); Sealing the wrapping material into a sealed bag; and applying pressure to the closed bag and the fiber carpet arranged therein to homogenize a distribution of fibers of the fiber carpet in the closed bag.
  • cellulose fibers are advantageous from an ecological point of view as they can be obtained from recyclable materials such as waste paper. Consequently, CO 2 consumption is significantly reduced compared to using EPS. Furthermore, the use of cellulose fibers enables energy-efficient production, in which, for example, energy expenditure can be reduced to 5 to 10% compared to the production of conventional EPS insulating packaging. Recycling materials made from cellulose fibers is also very easy. It can be disposed of like waste paper, for which there are established recycling processes for both private households and industrial applications.
  • the cellulose fibers provide the desired insulating effect.
  • they preferably have a low thermal conductivity, which is, for example, 36 mW/m*K (lambda).
  • This thermal conductivity is, for example, better in terms of its insulating effect compared to known blown insulation materials with a thermal conductivity of 40 mW/m*K (lambda) and almost as high as the thermal conductivity of EPS.
  • a particularly low thermal conductivity of cellulose fibers can be achieved if the fibers are short and thin. Short and thinner fibers can be more flexible and thus form more homogeneous cellulose materials with a uniform pore size distribution. With longer fibers, the air inclusions can be more uneven, which can lead to an inhomogeneous density distribution and a fluctuating mass distribution in the longitudinal and transverse directions. Thermal bridges can be formed, which lead to an increase in thermal conductivity.
  • low fiber fibrillation - fibrils are fine hairs on the fiber surface that point into free space and can come into contact with other fibers - can be beneficial for the insulating properties of cellulose fibers. Fibrils can act as spacers between the fibers and thus support the formation of a fine-pored structure with a high air volume inclusion.
  • the cellulosic fibers are provided by defibrating shredded cellulosics comprising cellulosic fibers.
  • shredded cellulose materials are obtained by shredding cellulose materials.
  • the cellulose material can include paper, cardboard, waste paper and newspapers.
  • cellulose material for example, is understood to mean all materials that consist primarily of cellulose fibers.
  • recycled waste paper B12 can be used.
  • Waste paper or mixed paper B12 is made up of newspapers, cardboard and writing paper, although it should preferably contain a maximum of 40% newspapers or magazines.
  • the extracted air which can also be referred to as residual air, includes, for example, suspended matter and dust particles contained in the air, e.g. fine dust, and individual loose cellulose fibers.
  • the cellulose material can be shredded using a single-shaft shredder.
  • Shredded cellulose includes, for example, shredded paper and cardboard shreds.
  • the shredded cellulose can be stored in a silo.
  • a eddy current mill the shredded cellulose material can be defibered into cellulose fibers.
  • Cellulose fibers can be transported using an air stream or a conveyor belt.
  • a cyclone separator can be used to remove residual air from the cellulose fibers. In this way the cellulose fibers can be compacted. Residual air can be cleaned using a filter tower.
  • a measured amount of cellulose fibers loosely bonded together can form the cellulose fiber bundle.
  • the cellulose fiber bundle can be loosened at at least two different positions, which are spatially separated from one another in a transport direction of the cellulose fiber bundle.
  • the cellulose fiber bundle is loosened by means of at least a rotating loosening rotor.
  • the rotating loosening rotor can be electrically driven.
  • the cellulose fiber bundle can rest on the rotating loosening rotor due to gravity.
  • At least two loosening rotors are preferably provided.
  • the loosening rotor can comprise a rotating shaft or can be designed as such.
  • the cellulose fiber bundle can form a fiber web before its cellulose fibers enter the feed unit. Air can be removed during the introduction of the cellulose fibers of the cellulose fiber bundle into the feed unit and/or in the feed unit.
  • the fiber carpet is formed by introducing the cellulose fibers of the cellulose fiber bundle into the wrapping material and compacting them. In other words, the fiber carpet is made by compacting the cellulose fibers.
  • the wrapping material preferably comprises a plastic-coated paper layer and/or a plastic material.

  • the compression unit can comprise at least one circumferential pressure belt, the distance of which from an opposite surface can be changed, so that air escapes from the casing material while the distance is reduced.
  • the opposite surface can be formed by the second printing unit.
  • the printing belt and the opposing surface may be arranged vertically.
  • the opposite surface or the second printing unit can comprise a further rotating printing belt.
  • the at least one pressure band ensures an even distribution of the fiber carpet within the covering material.
  • the at least one printing belt comprises, for example, a revolving belt, ie a belt guided over two revolving rollers, so that the wrapping material moves in the transport direction due to the movement of the printing belt.
  • the wrapping material is completely closed after the fiber carpet has been compacted, i.e. preferably no air can enter or escape from the wrapping material.

  • suction channels can be provided for extracting dust particles.
  • Such suction channels can prevent individual cellulose fibers and/or dust particles from being present in the area of the sealing surface.

  • the covering material with the fiber carpet contained in it i.e. the insulating packaging, can also be further processed into an insulating bag.

  • the length of the fiber carpet can be between 30 and 200 cm or more than 200 cm. Larger dimensions of the fiber carpet allow the insulating packaging to be used with few or no thermal bridges. If the fiber carpet is inserted into a shipping box, for example, due to its length it can be guided around edges or corners and cover them without a thermal bridge. An example of using the insulated packaging in a packaging box will be described in more detail later.
  • the wrapping material can, for example, form a completely closed bag by means of sealing sections.
