Definitions

  • the present invention relates to a process for making film sachets.
  • material losses due to cut-offs during the process are prevented.
  • the sachets made according to the process herein are useful for containing cleaning articles, for example, moistened cleaning wipes.
  • an individually-packaged wipe has been disclosed.
  • the sachet of this wipe provides improved packaging in terms of enclosure of the article packaged therein together with an improved opening functionality.
  • the opening functionality is provided by a graspable flap of package material, by which the user can peel open the sachet for dispensing the wipe. By the peeling a heat seal is broken, which is due to the specific layering of the sachet material used "weaker" that the side seals of the sachet.
  • This type of sachet can be conventionally produced by processes comprising the steps of folding a strip of film material along two parallel folding axes, such that the ends of the strip are folded inwardly and positioned onto each other with some overlap. Thereafter, the folded strip is sealed along its periphery outside the fold lines. One further sealing line is provided in the area of overlap of the ends of the strip.
  • the thus formed sachet is completely closed but still empty.
  • the closed sachet has to be opened again. This is done by cutting off a piece of material parallel to one of the fold lines. Thereafter, the article is placed into the interior of the opened sachet, which is then closed again by a sealing line along the open edge.
  • a process of this kind is disclosed in EP 696 991 .
  • the process of the present invention further comprises step i) cutting in machine direction in the area of the side seals, wherein step i) is carried out at any stage of the process after step f).
  • Cross-direction refers to a direction extending generally perpendicularly to the machine direction in the plane of the film material.
  • Film material refers to a flat layer of material suitable for forming hygienically satisfying sachets for personal care articles.
  • Exemplary film materials include polymeric film materials comprising PE, PP, PVC and the like. Further suitable film materials include metallised polymeric films or laminates of polymeric materials.
  • An especially useful film materials of the latter kind is the multilayer laminate material disclosed in EP 696 991 . This material has an outer layer made of a PE/OPP coextruded layer on one surface, with the PE side oriented outwardly, and a PE layer on the opposite surface. By using materials like those disclosed in EP 696 991 it is possible to form heat seals of variable strength.
  • the film material used herein may have moisture barrier properties. This can be provided by incorporating moisture barrier layers into the film material, like layers of metals, like aluminium, or layers of EVOH (ethylene vinyl alcohol) or by other known means.
  • Sealing refers to suitable measures for attaching one piece material to another.
  • Exemplary sealing and joining methods are heat sealing, pressure sealing, gluing, crimping, ultrasonic bonding, mechanical entangling and/or other known sealing means and or methods.
  • the process of the present invention can be structured into the following steps:
  • Step i) can be carried out at any stage of the process after step f).
  • the separation can be carried out by any suitable cutting means, including cutting knives, cutting rollers, heat cutters, ultrasonic cutters, laser cutters and combinations thereof.
  • steps b)-d i.e. cutting the film material, displacing it onto each other, and sealing it in the area of overlap the process can be significantly simplified.
  • the structure, which later forms the peelable flap for opening the sachet is generated at an early stage of the process. Therefore the need to cut the sachet open for inserting a personal care article into the sachet followed by a reclosing step does not exist anymore.
  • sachet material can be saved.
