Definitions

  • the invention relates to a packaging bag for light sanitary articles such as diapers.
  • packaging bags for diapers are so-called wicket bags made of plastic.
  • wicket bags are extremely inexpensive, they are not environmentally friendly due to their plastic nature, which is increasingly undesirable.
  • the packaging bag according to the invention is made from a piece of tubing comprising one or more layers of paper. With the manufacture of paper the desired environmental friendliness is achieved.
  • the invention includes single-ply or multi-ply paper bags. Single-ply paper bags are particularly preferred because they can be produced using fewer resources and are therefore more environmentally friendly. In addition, single-ply paper bags are cheaper to produce. Multi-layer paper bags, on the other hand, enable safer and more stable packaging.
  • a bottom is formed at one end of the tube piece, preferably as a cross or block bottom. Opposite the bottom is the upper part, through which the bag is filled.
  • the wall of the bag extends like a tube between the bottom and the upper part.
  • the upper part is closed with a wet adhesive strip.
  • the wet adhesive strip is formed from a paper strip which is coated with starch glue and/or with another wet adhesive, the wet adhesive preferably being biodegradable. A high level of environmental friendliness can be achieved by closing the bag with such a wet adhesive strip. Both the paper strip and the applied starch glue or preferred wet glue are easily biodegradable.
  • Potato starch glue is advantageously used because of its good adhesive properties.
  • the starch glue or wet glue applied to the paper strip is characterized in that it can be activated by moistening, i. H. By moistening, the adhesive effect of the starch glue or wet glue can be activated at the desired point in the manufacturing process.
  • the wet adhesive strip is unwound from an endless roll of wet adhesive tape in the production process, then moistened in a moistening station and then, after separation from the endless tape, glued onto the packaging bag.
  • the aforementioned endless roll with wet adhesive tape is preferably an endless paper tape which is provided with a wet adhesive coating, preferably a coating of starch glue, more preferably potato starch glue.
  • a wet adhesive coating preferably a coating of starch glue, more preferably potato starch glue.
  • starch glue more preferably potato starch glue.
  • the wet glue coating is typically dry, ie not activated. As long as the wet glue or starch glue applied to the paper tape or strip is not moistened or activated, simple machine processing is possible.
  • the ability to be activated by moistening makes it possible to create the adhesive effect at the desired point in the production process, advantageously shortly before the wet adhesive strip is separated from the endless belt and/or before the wet adhesive strip is applied to the upper part of the packaging bag according to the invention.
  • the piece of tubing has a staggered cut at the end of the upper part of the packaging bag, which forms a projecting flap.
  • the plastic wicket bags known from the prior art also have such a tab. This facilitates the mechanical processing of the packaging bags according to the invention on machines on which previously known plastic wicket bags are processed. This means that investment costs for such machines are not lost; rather, these investments can continue to be used without or through suitable redesign of the machines, which makes it easier to switch to the more environmentally friendly paper packaging.
  • two or more holes and/or two or more crossed perforation lines are applied in the area of the flap.
  • the holes and/or perforation lines are advantageously arranged in pairs.
  • the previously known plastic wicket bags also have such holes.
  • the holes or perforation lines in the packaging bags according to the invention therefore improve the machinability on machines for previously known plastic wicket bags.
  • the crossed perforation lines have the advantage that there is no punching, as is the case when holes are punched out.
  • the disadvantage of creating a diecut is that it has to be removed and disposed of during the production process. This disposal of the die-cut is avoided if, instead of the holes, crossed perforation lines are introduced into the tab.
  • the perforation lines intersect advantageously at right angles, and further advantageous are the ends of crossed perforation lines on the circular line of a circle whose center is at the crossing point of the perforation lines.
  • the aforementioned circle is advantageously the edge of an imaginary hole, which is replaced by the crossed perforation lines.
  • the diameter of the holes or imaginary holes is advantageously of the order of one centimeter.
  • the bottom of the packaging bag according to the invention is also glued with a wet adhesive strip.
  • the wet adhesive strip is also formed from a paper strip with a coating of starch glue and/or other biologically degradable wet glue, with the starch glue or wet glue being activatable by moistening.
  • the starch glue or the wet adhesive coating is applied over the entire surface of the wet adhesive strip or strips.
  • the starch glue or the wet-adhesive coating is applied to the wet-adhesive strip only in delimited areas, in particular in a specific adhesive contour.
  • the starch glue or the wet adhesive coating is admixed with additives that increase the adhesion of the activated or moistened wet adhesive strip.
  • Starch glue without additives typically has low adhesion when wet, which means that the bonded objects slip comparatively easily against each other as long as the starch glue is wet or activated. This poor adhesion can be avoided by adding suitable additives, so that the bonded objects no longer slip against each other so easily, even if the starch glue is still wet or activated.
  • the packaging bag is provided with a water-repellent coating on its outside.
  • the water-repellent coating can be applied to the outside of the outermost paper layer of the wall of the bag.
  • the water-repellent coating prevents the bag and its contents from getting wet.
  • the water-repellent coating is particularly preferably applied to the entire surface of the outside of the packaging bag.
  • the intended moisture protection can also be achieved if individual areas of the outside of the bag are not provided with the water-repellent coating, e.g. B. the outside of the glued wet adhesive strip.
  • the water-repellent coating is biodegradable and/or compostable and/or recyclable.
  • the packaging bag according to the invention is provided with a carrying handle and/or an opening aid on the bottom.
  • the opening aid is preferably a tear strip worked into the base. If the bottom of the pouch is sealed with a wet-seal strip, the tear strip may be incorporated into the wet-seal strip.
  • the invention also relates to a method for packaging packaged goods in recyclable paper packaging.
  • the packaged goods are packed in an open cross or block bottom paper bag.
  • the packaged goods are introduced into the empty packaging bag through the opening opposite the cross or block bottom, and the opening is then folded shut.
  • the folded opening is fixed with a wet adhesive strip previously activated by moistening.
  • the wet adhesive strip is described as a paper strip with a wet adhesive coating.
  • the wet-adhesive coating preferably consists of starch glue, more preferably potato starch glue, and more preferably covers the entire surface of the paper strip upset.
  • the wet adhesive coating can include additives that increase the adhesion of the moist or activated wet adhesive.
  • the packaging bag is preferably provided on its outside with a water-repellent coating which is advantageously biodegradable and/or compostable and/or recyclable.
  • the wet-adhesive strip is unwound from a continuous roll of wet-adhesive tape, as already described above, then activated by moistening in an activation station and then, after being separated from the continuous tape, glued to the packaging bag.
  • the aforementioned endless roll with wet adhesive tape is preferably an endless paper tape which is provided with a wet adhesive coating, preferably a coating of starch glue, more preferably potato starch glue.
  • a full-surface coating with the wet adhesive is advantageously a full-surface coating with the wet adhesive.
  • the wet adhesive coating is typically in a dry state, i.e. not activated or tacky. As long as the wet adhesive applied to the paper tape or strip is not moistened or activated, simple mechanical processing is possible.
  • the bottom of the packaging bag is also glued with a recyclable wet adhesive strip.
  • a tear-off strip is incorporated into the wet-adhesive strip, which makes it easier to open the bottom to remove the contents of the bag.
  • the invention protects the use of a packaging bag according to the invention or a method according to the invention for the packaging of diapers or other light-weight sanitary articles.
  • the known wicket bags made of plastic are used in the prior art in particular for the packaging of diapers, so that the use according to the invention makes a considerable contribution to environmental protection could be done.
  • the packaging bag made of paper is preferably mechanically sealed with a moisture-activated wet adhesive strip after it has been mechanically filled with the diapers and the upper part has been folded shut by machine. When used according to the invention, the packaging is advantageously carried out entirely by machine.
