The present invention provides a packaging unit for hygiene articles, the unit being formed from a sheet of material having an inner surface and an outer surface. The inner surface comprises an edge zone comprising an inner edge portion and an outer edge portion. The sheet has at least one folding axis dividing the sheet into a first region and a second region. The inner edge portion and the outer edge portion of the edge zone of the first region is provided with adhesive, and the other of the inner edge portion and the outer edge portion of the edge zone of the first region is adhesive-free. Further； one of the inner edge portion and the outer edge portion of the edge zone of the second region is provided with adhesive, and the other of the inner edge portion and the outer edge portion of the edge zone of the second region is adhesive-free in a complementary manner to the edge zone of the first region. Thus,when the sheet is folded about the folding axis, the edge portion carrying adhesive in the first region is brought in contact with the adhesive-free edge portion in the second region, and the edge portion carrying adhesive in the second region is brought in contact with the adhesive-free edge portion in the first region. Moreover, at least a section of the adhesive-free edge portion in at least one of the first and the second regions is provided with a release agent.
