  • the term "hygiene article” is understood to mean, in particular, diapers, incontinence products, feminine hygiene products, panty liners, but also absorbent bed liners or underlays.
  • Such incontinence articles are typically compliantly flexible and compressible, resulting in packaging on the one hand with the possibility of volume reduction and on the other hand with stability issues in stacking as packages form.
  • edge support angles For the production of cartonage-free arrangements of bag packages, the use of so-called edge support angles has already been proposed, see for example EP 2 116 479 A1, which extend along vertical edges and are intended to have a stabilizing effect.

  • the arrangement comprises a plurality of separate secondary packages combined units of a plurality of bag packages, said secondary packages are arranged on a base next to each other and in a first direction perpendicular to this base one above the other; a respective secondary package is formed by disposing a respective one of a plurality of bag packages in a cuboid shape and fully enclosing and thereby compressing this cuboid form of two separate stretch film wrappings oriented 90 degrees apart in a respective resulting circumferential direction of the stretch film wrapping; the secondary packages stacked on top of each other and in the first direction are held together by a plurality of stretch film windings to form the assembly; the stretch film windings comprise head windings substantially completely overlapping each other, foot windings substantially completely overlapping each other, and helical windings helically leading from the head windings toward the foot windings, and helical windings helically extending from the foot windings toward lead the head windings, wherein additionally between the head

  • units of several such bag packages about 2 to 24, in particular 2 to 10 and in particular 4 to 8 bag packages are formed, wherein a cuboid shape and in particular a cube shape is obtained.
  • the head windings are provided at the upper end of the assembly, that is, facing away from the base, and substantially with a circumferential direction extending in a plane substantially perpendicular to the first direction. They overlap completely, which means that a film web overlaps the preceding film web and preferably also the remaining film webs by at least 90% in width.
  • the foot windings run in the base-facing lower region of the arrangement. If the base, for example in the form of a pallet, is integrated into the arrangement, then the foot windings always comprise at least part of the base, so that the secondary packings are connected to the base or fixed to the base in this manner.
  • helical windings running in two directions ie with opposite pitch of the "threads" are provided. They preferably connect directly to the head windings or foot windings, but this does not necessarily have to be the case.
  • the aforementioned support windings are provided between the head windings and the foot windings, whose circumferential or winding direction - as in the head windings and foot windings - extends in a plane substantially perpendicular to the first direction.
  • the support windings have a substantially complete coverage, which in turn means that an overlap in the width of at least 90% is realized between stacked support windings.

  • the first stretch film wrapping applied to the parallelepiped shape and the second stretch wrapping applied to the parallelepiped form rotated by 90 degrees thus result in a secondary packing in which the flat material webs forming the stretch film wrapping lie twice over one another on two opposite sides of the cuboid shape.

  • the folded hygiene articles are arranged with their flat sides lying against each other and forming a stacking form in a respective bag pack and the orientation of the stack shape within those bag packages which form a secondary pack is the same and the stretch film wrapping attached first to the cuboid shape is attached to the parallelepiped shape such that a flat material web forming the stretch film wrapping runs along the edges of the folded hygienic articles and thus orthogonal to their flat sides.
  • the stretch film wrapping secondly attached to the cuboid form extends parallel to the flat sides of the sanitary articles on two opposite sides of the parallelepiped shape.

  • the folded sanitary articles can be compressed further in their stacking direction and damage to the hygiene articles by folding or crushing at the edges of the folded hygiene articles can be kept low.
