A packaging unit having improved sealing, and a method for forming such a packaging unit

Abstract

The present invention provides a packaging unit for hygiene articles and a method of forming such a unit. The packaging unit is formed from a sheet of material having an inner surface and an outer surface, wherein the inner surface comprises an edge zone comprising an inner edge portion and an outer edge portion. The sheet has at least one first folding axis, dividing the sheet in to a first region and a second region. One of the inner edge portion and the outer edge portion of the edge zone of the first region is provided with resealable adhesive, thus forming a first adhesive zone, 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, the inner edge portion or the outer edge portion of the edge zone of the second region corresponding to the adhesive-carrying edge portion of the first region is adhesive-free, such that when the sheet is folded about the first folding axis, the edge portions carrying resealable adhesive in the first region are brought in contact with the adhesive-free edge portions in the second region. A distance between the at least one first folding axis and the first adhesive zone is 1-20mm, preferably 2-18mm, more preferably 3-15mm.

Description

technical field [0001] The present invention relates to a packaging unit for hygiene articles, wherein the packaging unit provides a tightly sealed package when packaging new hygiene articles and when discarding used hygiene articles. The invention further relates to a method for forming a packaging unit. Background technique [0002] Disposable hygiene items such as sanitary napkins and pantiliners are often individually packaged in simple or individual packages. Individual packaging facilitates hygienic carrying of individual items for future use, eg in a handbag. The edges of the individual packs are usually sealed by ultrasonic welding or heat welding. In addition, packaging units are often used as a means of packaging unused items and discarding used items. [0003] It is desirable that such used items be able to be separated and disposed of hygienically. This may be particularly important when the user cannot immediately discard the used item after replacing it, fo...

AI Technical Summary

Problems solved by technology

[0005] However, it has been found that the manufacturing process of the packaging unit described in WO 2013 / 162430 can be adversely affected by the presence of edge portions carrying adhesive

For example, during the folding step, the adhesive disposed on the edge portion of the packaging unit may be caught by the folding tool, which would cause transfer of the adhesive from the packaging unit to the tool, or would result in inaccurate folding

Both cases will impair the manufacture of packaging units
