Definitions

  • the proposed invention concerns a method for the production of a film bag, a film bag with a flat bottom, in particular, with longitudinally sealed reinforcing foldings, and the packaging machine intended for the production of this film bag.
  • Assorted types of film bags have been available, which are used to pack small wares and food as namely spices, sweets, etc. It is a question of a film tube bag with a folded flat quadrilateral bottom and with welded longitudinal foldings, for instance.
  • the bottom comprises a lower cross seam.
  • the bag is equipped with a plastic zipper closure in the upper part of its inner body, said zipper comprising two parts.
  • the zipper closure represents a secondary closure.
  • the primary closure is formed by an upper cross seam and is situated above the secondary closure.
  • a user removes the primary closure formed as an upper cross seam to open such a bag. Then, he opens the bag in the way to draw out mutually connected parts of the zipper closure from each other.
  • the user has a disposal of a round hole to enter the bag at maximum, the space of which results merely from the openable length of the closed zipper closure—the closure has both its parts mutually welded at the ends for the reason of its easier locking, in principle.
  • the method for production of such a bag is performed so that the packing film is wound up to form a film tube on which the longitudinal foldings are shaped and sealed. Thereafter, the film tube is insulated by the lower cross seam in its bottom part, whereas the folded bottom of the bag is formed simultaneously.
  • the two-piece zipper closure is applied to the bag in the following way.
  • both parts of the zipper closure which are mutually inserted into each other, are welded by its single part onto the packing film, which shall subsequently be shaped as a film tube with longitudinal foldings that are sealed, thereat.
  • the zipper closure must be placed on the packing film in order to enable its positioning on the resulting bag on the inner surface of the front, or rear side of the bag. Therefore, the zipper closure is shorter a bit than the width of the bag side to which it is applied to, in this case.
  • the method for the film tube bag production is the subject matter of the invention. This method comprises the following operations:
  • the longitudinal axis of the secondary closure is perpendicular to the longitudinal axis of the longitudinal foldings.
  • the secondary closure is positioned so that it is located under the upper cross seam on the finished bag and the length of the applied secondary closure corresponds to the size of the inside circumference of the bag. It means that the length of the secondary closure reaches its maximum potential. In terms of an optimum case, it is identical to the size of the inside circumference of the bag.
  • the secondary closure with a reasonably shorter length is used to be respected in practice in consideration of necessary manufacturing tolerance. Thus, the beginning and the end of the secondary closure are prevented from overlapping each other in the finished bag, which is unacceptable regarding the requested tightness. A very small incidental spacing between the beginning and the end of the secondary closure is generally not considered a defect;
  • the secondary closure is composed of a one-piece zipper closure in the convenient embodiment of the invention, in particular.
  • the secondary closure can be composed of a double-sided adhesive tape in another convenient embodiment.
  • the side of the adhesive tape glued on the inner side of the bag indicates a higher binding property than the other side.
  • the adhesive layer situated on the side of the strip facing inward of the bag enables to separate the strips repeatedly and connect them again, and thereby the sides of the bag, as well.
  • the secondary closure is composed of a spread of a permanent adhesive in another convenient embodiment of the invention. That enables to separate the inner sides of the bag repeatedly and connect them again at the point of the secondary closure.
  • the fourth longitudinal folding is formed by a latterly formed longitudinal seam. It means that three corners of the bag are equipped with longitudinal folding and the fourth corner of the bag with the longitudinal seam. Thanks to this fact, the longitudinal seam does not have to be positioned in a certain (in the rear side, generally) side of the bag.
  • the machine comprises (in the direction of the packing film movement) the following: a device for packing film unwinding, which is followed by the device for shaping and fixing longitudinal folding on the packing film. It is followed by a device for an application of the one-piece secondary closure on the packing film with formed longitudinal foldings. Thereinafter, a forming collar, a filling tube as well as a longitudinal sealing jaw to manufacture the longitudinal seam follow. There is a device for the packing film feed leading through the forming collar in the space below the forming collar. Furthermore, it is followed by a device enabling to form the flat bottom of the bag, and lateral sealing and separating jaws to manufacture the cross seam, and to separate the filled bag.
  • the packing film runs through all mentioned components of the machine where it is gradually processed in the form of a filled film tube bag closed by the primary and secondary closures.
  • a stable bag is elaborated thanks to the previously mentioned production method including advantages manufactured by the described machine, equipped with the secondary closure, which has a disposal of a large opening to access the inwards of the bag.
  • the area of such an opening stems from the circumference of the whole bag and is on order of tens of percentages higher than at the application of a common two-piece zipper closure.
  • FIG. 1 The film tube bag with a flat bottom, secondary closure and longitudinal reinforcing foldings
  • FIG. 2 The layout of the vertical form fill seal packaging machine with the device for an application of the secondary closure.
  • Exemplary method for the film tube bag 1 production comprises the following sequential consecutive operations:
  • the all-round secondary closure 5 which longitudinal axis is perpendicular to the longitudinal axis of longitudinal foldings 6 on the inner side of the packing film 8 .
  • the all-round secondary closure 5 is situated in the way that it is placed inside the finished bag below the upper cross seam 2 .
  • the secondary closure 5 is formed by a one-piece zipper closure and the length of the applied secondary all-round closure 5 corresponds with the size of the bag inside circumference;
  • the longitudinal seam 7 is located in one of the corners of the bag 1 , and it forms the fourth longitudinal folding 6 , simultaneously;
  • the vertical form fill seal packaging machine used for the above described method for the film tube bag production comprises the device 11 for the unwinding the packing film 8 followed by the device 12 for welding longitudinal foldings 6 on the packing film 8 .
  • another device 17 shall be integrated in the machine with the aim to apply a one-piece secondary all-round closure 5 on the packing film 8 with formed longitudinal foldings 6 .
  • FIG. 1 and FIG. 2 Exemplary embodiment shall be depicted in FIG. 1 and FIG. 2 .
