Method for producing packaging for an item and packaging
A method for producing packaging for an item and to a packaging for an item is provided. The method provides for the following: providing a container material consisting of a leaf material from a plant; shaping the container material into a three-dimensional packaging container having a container opening and a container edge surrounding the container opening; producing a sealing edge on a top surface of the container edge, wherein the top surface of the container edge is sanded down by sanding; placing an item in the three-dimensional packaging container through the container opening and sealing the container opening by a sealing film, wherein the sealing film is adhesively bonded to the sealing edge in an adhesive-free manner.
1. A method for producing packaging for an item, comprising:
providing a container material comprised of a leaf material from a plant;
shaping the container material into a three-dimensional packaging container comprising a container opening and a container edge surrounding the container opening;
producing a sealing edge on a top surface of the container edge, wherein the top surface of the container edge is sanded down by sanding;
placing an item in the three-dimensional packaging container through the container opening; and
sealing the container opening exclusively in a region of the sealing edge by a sealing film such that the sealing film is not folded down from the top surface to cover an outer edge of the container below the container edge and avoids touching an inner surface of the packaging container, wherein the sealing film is adhesively bonded to the sealing edge in an adhesive-free manner;
wherein the sealing edge is produced by sanding after the shaping of the container material;
wherein, after the shaping the container material, only the top surface of the container edge is sanded.
2. The method according to claim 1 , wherein a plastics film is used as the sealing film.
3. The method according to claim 1 , wherein a compostable plastics film is used as the sealing film.
4. The method according to claim 1 , wherein when sealing the container opening, the following is also provided:
supporting the container edge comprising the sealing edge on a support tool; and
pressing the sealing film by a pressing tool against the sealing edge on the container edge, the sealing film being heated in the process in such a way that the sealing film partially melts for adhesive bonding to the sealing edge on the container edge.
5. The method according to claim 1 , wherein a palm leaf is used as the leaf material.
6. The method according to claim 1 , wherein a leaf material comprising a barrier layer is used as the leaf material.
7. The method according to claim 1 , wherein the leaf material is moistened, heated and compression-molded during shaping.
8. The method according to claim 1 , wherein the container edge is smoothed during sanding to produce the sealing edge, with surface-side leaf structures of the leaf material being sanded down.
9. The method according to claim 1 , wherein the sealing edge is produced by a uniform sanding process in which the container edge is laid flat in its entirety on a sanding surface which grips the container edge surrounding the container opening in its entirety.
10. The method according to claim 1 , wherein when the container material is shaped as the three-dimensional packaging container, a container from the following group is produced: tray, plate, mug, and bowl.
11. The method according to claim 1 , wherein the container opening is sealed in a liquid-tight manner by the sealing film.
12. Packaging for an item, comprising:
a three-dimensional packaging container comprised of a leaf material from a plant;
a container opening;
a container edge which is formed on the three-dimensional packaging container so as to surround the container opening;
a sealing edge which is formed on a top surface of the container edge as a sanded surface;
an item placed in the three-dimensional packaging container through the container opening; and
a seal formed by a sealing film exclusively in a region of the sealing edge such that the sealing film is not folded down from the top surface to cover an outer edge of the container below the container edge and avoids touching an inner surface of the packaging container, wherein the sealing film is adhesively bonded to the sealing edge in an adhesive-free manner;
wherein the sealing edge is produced by sanding after the shaping of the container material;
wherein, after the shaping of the container material, only the top surface of the container edge is sanded.
13. The packaging according to claim 12 , configured as recyclable packaging.
