Definitions

  • the invention relates to a method for producing a packaging bag made of paper, plastic or a composite with these materials, a window arrangement on the front wall of the bag having.
  • the object of the invention is a method for producing a Packaging bag with viewing window arrangement and a reinforcement to create in the field of vision, which is particularly material-saving and can be carried out inexpensively and where Reinforcement and the actual bag material in the area of Window cut-outs always lie cleanly on top of each other.
  • the stamped parts resulting from the punching of the individual fields of view can be removed by suction or air jets. It is particularly advantageous if the roll is flat unwound main line with the also unwound from a roll Reinforcement sheet laminated by surface gluing , the width of the reinforcement sheet being greater than that Width of the total field of view formed by the individual viewing windows.
  • the same material is expediently used for the reinforcement used as for the packaging bag itself.
  • For a packaging bag paper is therefore advantageously a paper reinforcement used.
  • the use of the same materials for the Bag and for its reinforcement in the field of view leads to a packaging bag that is completely made up of just one Material manufactured and therefore without prior material separation can be recycled.
  • a material can be used, for example Paper, cardboard, plastic and the like, its strength property or tensile strength of that of the material of the packaging bag deviates.
  • the reinforcement can also consist of a material whose tensile strength is greater than that of the bag material, which results in the same material can be achieved that the reinforcement strip a larger Has wall thickness.
  • the reinforcement can thus be on the main line for the Bag blanks are glued on so that they are over afterwards extends the entire height of the packaging bag, but it can also be designed so that they essentially only the entire field the single viewing window covers.
  • the packaging bag and the type of Packaged goods can be the number of single-view windows that during the production of the bag by the main line and the Reinforcement punched out to be different.
  • the neighboring individual viewing windows are expediently at a distance arranged to each other, which is smaller than their width or opening width, whereby the are at a relatively close distance from each other arranged individual viewing windows in their entirety Larger control window in the finished one, interrupted by webs Bags result in a good control of the packaged goods enables.
  • the shape of the individual viewing window can be designed differently. Decorative shapes are also possible here. in the it is generally advisable to provide single viewing windows, which is at least approximately a rectangular or square Have an outline, preferably with rounded corner areas.
  • the packaging bag 1 shown in the drawing is e.g. made of paper and consists of a block bottom bag. It has two carrying handles on its lockable top 2 provided. It has a viewing window arrangement on its bag front wall 3 with several single view windows 4 on their Opening are not covered, so not in the conventional Way through network elements or transparencies or the like. covered are. To prevent that in the packaging bag 1 too Packing, packaged packaged goods from the individual viewing windows 4 falls out, they have an opening width that is smaller than the piece size of the product.
  • the packaging bag 1 on its front, or on its front wall 3, the individual viewing windows 4 in three parallel horizontal rows, whereby three individual viewing windows 4 are arranged within each horizontal row are.
  • the individual viewing windows 4 face each an at least approximately rectangular or square Outline, but with its edges, and also useful their corner areas are rounded. Otherwise they are adjacent individual viewing window 4 at a distance from one another arranged, which is significantly smaller than their width, or their Opening width.
  • the packaging bag is in these web areas 1 reinforced.
  • the reinforcement consists of a reinforcement strip, preferably of the same material as the bag itself, in the case of a paper bag, that is expediently from a paper strip, although reinforcement strips made of other materials, e.g. made of plastic, can be used.
  • Fig. 2 shows that the reinforcement 6 on the inside of the bag front wall 3 glued flat and to the individual viewing windows 4 congruent openings or punchings 7 is provided. The web areas 5 are thus in the overall field of the individual viewing windows 4 with regard to the filling weight of the packaged packaging bag 1 sufficiently reinforced.
  • the reinforcement strip 6 over the entire height of the bag front wall 3 and also extend into or over the bottom area 8 thereof.
  • the width of the reinforcement strip forming the reinforcement 6 can be approximately the same or smaller than the width of the packaging bag 1 or its bag front wall 3, depending on the training and arrangement of the individual viewing windows 4. On the other hand it can also be useful for reasons of material savings be, the reinforcement 6 only in the area of the field of the individual viewing window 4 to be provided, using reinforcement strips that are only about the height and width of the overall field the single viewing window 4 extend.
  • the reinforcement 6 preferably consists of the same material as the packaging bag 1.
  • the preferred packaging bag 1 made of paper is accordingly a reinforcement 6 used from a paper strip so that the bag with reinforcement made entirely from a single material consists.
  • the blank of the packaging bag 1 shown in FIG. 3 comprises in addition to the bag front wall 3 and the bottom area 8, the with rear windows 9 and the two side areas 10 of the bag.
  • the described packaging bag 1 are manufactured in such a way that of a roll 11, the main web 12 for the bag cuts in the direction of arrow 13 and from another roller 14 Web 15 for the reinforcement 6 in the direction of arrow 16 unwound flat are, the webs 12 and 15 brought together on two rollers 17 will.
  • the reinforcement track 15 over the entire surface by means of a glue application device 18 or selectively coated with adhesive so that they stick to the pressure rollers 17 with the main web 12 or with the finished Bag whose front wall 3 forming area is glued.
  • the main web 12 thus laminated with the reinforcement web 15 becomes behind the rollers 17 by means of a punching device 19, which by rotating punching knives is formed, punched, resulting in one Operation all individual fields of view 4 through the main track 12 and the reinforcement sheet 15 bonded to it be punched out.
  • the resulting stamped parts can by means of a suction device, not shown, or be removed by means of air jets.
  • the main web 12 laminated with the reinforcement web 15 in the usual way Formed into a bag tube, from which then how known, the packaging bag 1 are manufactured. Manufacturing technology It is particularly advantageous that the main track 12 and the reinforcement track 15 after their union to form the Individual viewing windows can be punched through simultaneously.
  • the method described above can be changed so that that the reinforcement web 15 unwound from the roll 14 before they are glued to the main track 12, first across is severed, whereby the individual reinforcement web 15 Reinforcement strips are separated, which then after Apply adhesive in the area of the rollers 17 with the main web 12 be connected, whereupon the punching out with the reinforcement strip laminated main web 12 in the described Way is done.
  • the reinforcement track 15 cut reinforcement strips 16 dimensions obtained which are smaller than the height of the packaging bag or its bag front wall 3 and its height and width is expediently only a little larger than the dimensions the total field of the individual viewing windows 4.
  • the packaging bag 1 can optionally be used as a block bottom bag, as a cross bottom bag, as a bottom gusset bag or can also be designed as gusseted flat bags. He can, instead of paper, also plastic or paper or Plastic composite materials are manufactured.
  • the size of the Individual fields of view 4, as mentioned, is chosen so that the smallest part in the packed product is not due to the Windows can fall through to the outside. Preferably under this requirement size the window so large that a good visual inspection of the packaged product is possible.
  • the Number, arrangement and shape of the individual viewing window 4 can be different, the width of the webs 5 expedient is adapted to the bag load caused by the packed goods, but is advantageously smaller than the edge dimensions or the opening width of the individual viewing windows 4.
