Definitions

  • the invention relates to a film bag made of a heat-sealable or weldable plastic film for receiving liquid and / or pasty media with two side walls forming surface parts which are sealed to one another at their longitudinal edges and at the lower cant and which form a removal opening at the upper end .
  • Such plastic film loot are particularly useful as disposable packaging for beverages, e.g. known from the German utility model G 88 07 593.1. Usually, these are pointed packaging with a filling volume of 0.2 l.
  • the films used in such beverage packaging have a thin aluminum film layer, which stabilizes the packaging, among other things.
  • Such foil bags are usually designed as stand-up bags. A bottom is incorporated into the bottom so that the prey can be placed on a support even after it has been opened, without the contents of the bag running out of the removal opening or the prey tipping over.
  • the removal opening can be predetermined by a predetermined puncture opening through which a straw tapering at its end can be pierced.
  • liquid or pasty media for example liquid detergents
  • plastic bags are mainly used as refill packs.
  • a fundamental advantage of the film bags can be seen in the fact that they can be folded up very flat in the unfilled state and thus take up little space.
  • Such foil bags are filled automatically with liquid or pasty media.
  • the foil bag is set up with its removal opening and a filler neck is inserted into the removal opening. After the foil bag is filled, the removal opening is welded or sealed.
  • the object of the invention is to provide a film bag whose removal opening or pouring spout can be opened easily for filling and which is particularly suitable for automatic filling.
  • the width of the respective beads should preferably be 5 mm to 10 mm, at least in the case of only one channel in each side wall.
  • each side wall should be congruent, but in mirror image three embroideries, the space or opening then formed between the side walls in the area of the opposite beads having the shape of a diamond. All the beads should run essentially parallel to one another, a width of about 0.5 mm to 1 mm being sufficient for each bead. In such a configuration of the removal opening, the central bead runs with its opening to the inside, i.e. towards the opposite side wall, while the two beads running to the left and right of this central bead form a groove on the outside of the foil bag. If several individual beads are made, they should have a maximum distance of 5mm to 10mm.
  • the beads have a shape in the longitudinal direction, i.e. in the direction of the longitudinal seams, such that they together form a funnel, i.e. these beads widen towards the end of the film bag or taper to the lower area of the film bag, a length of the beads between 10 mm and 50 mm being sufficient here as well.
  • All blanks from which the film bag is formed consist of a two-layer plastic film, as shown in section in FIG. 3.
  • the outwardly directed film 9, which forms the outer skin, is a polyester film with a thickness of 12 »m
  • the film 10» m which faces the interior of the film bag and forms the inner skin
  • a coextrusion film Manufactured polyethylene film deals.
  • Such a coextrusion film is built up in several layers and, depending on the requirements, the layer structure during the extrusion can be varied and adjusted according to the specific requirements.
  • the film 10 has a thickness of 150 »m, the film thicknesses given for a bag with a filling content of approximately 1 to 1.5 liters, and a maximum of 2 liters.
