Abstract

A packaging unit for hygiene articles and a method for producing the same. The packaging unit is formed from a sheet of material having an inner surface and an outer surface. The inner surface has an edge zone. The sheet has at least one folding axis and the folding axis divides the sheet into a first region and a second region. The sheet may be folded along the folding axes with the first and second regions in an overlapping configuration, and at least a part of the edge zone is provided with microencapsulated adhesive.

First claim

The invention claimed is:

1. A packaging unit for hygiene articles,
said packaging unit being formed from a sheet of material having an inner surface and an outer surface, said inner surface comprising an edge zone, said sheet having at least one folding axis, said folding axis dividing said sheet into a first region and a second region, said sheet being folded along said folding axes with said first and second regions in an overlapping configuration,
wherein at least a part of said edge zone is provided with microencapsulated adhesive,
wherein said edge zone includes an inner edge portion and an outer edge portion that separates said inner edge portion from a peripheral edge of said packaging unit, and
wherein one of said inner edge portion and said outer edge portion is provided with the microencapsulated adhesive and the other of said inner edge portion and said outer edge portion is provided with a first sealing means, said first sealing means being different from the microencapsulated adhesive such that one may be used to initially seal said packaging unit with a new hygiene article therein and another may be used to make a subsequent closure and seal of said packaging unit for wrapping and transporting a used hygiene article therein.

2. The packaging unit according to claim 1 , wherein the microencapsulated adhesive is applied on 10-50% of the area of the sheet of material.

3. The packaging unit according to claim 1 , wherein the microencapsulated adhesive is distributed over substantially the whole inner surface of the sheet of material.

4. The packaging unit according to claim 1 , wherein 0.1-30 g/m 2 of microencapsulated adhesive is added to the sheet of material.

5. The packaging unit according to claim 1 , wherein said first sealing means is selected from mechanical, heat and adhesive.

6. The packaging unit according to claim 5 , wherein the adhesive of the first sealing means is an adhesive having an adhesive strength between 0.3 and 3.5 N.

7. The packaging unit according to claim 5 , wherein the mechanical sealing means is selected from the group consisting of embossing, ultrasonic welding and hook and loop fasteners.

8. The packaging unit according to claim 1 , wherein said packaging unit is reclosable by said microencapsulated adhesive.

9. The packaging unit according to claim 1 , wherein said sheet of material is substantially rectangular and comprises longitudinal edges, transverse edges and corner portions, wherein said edge zone of said first and second regions of said sheet of material is arranged along said longitudinal edges.

10. The packaging unit according to claim 1 , wherein said sheet of material comprises transverse edge zones and wherein at least a portion of one of said transverse edge zones is provided with microencapsulated adhesive.

11. The packaging unit according to claim 1 , wherein the outer edge portion of said edge zone is provided with the microencapsulated adhesive, and wherein the inner edge portion of said edge zone is provided with the first sealing means.

12. The packaging unit according to claim 1 , wherein said sheet has two folding axes, dividing said sheet into a first region, a second region and a third region).

13. The packaging unit according to claim 12 , wherein said sheet is folded along said folding axes with said first, second and third regions in an overlapping configuration.

14. The packaging unit according to claim 1 , wherein said packaging unit is for individually wrapping an absorbent article.

15. The packaging unit according to claim 1 , wherein the packaging unit enclose an absorbent article comprising at least a topsheet and a backsheet.

16. The packaging unit according to claim 1 , wherein the sheet of material forming said packaging unit is a single ply material which does not comprise separable layers.

17. The packaging unit according to claim 16 , wherein the singly ply material is a polymeric film.

18. The packaging unit according to claim 1 , wherein the sheet of material also comprises a transverse edge zone which is free from adhesive to thereby form a grip tab on said packaging unit.
