Definitions

  • the invention relates to a pack, in particular a tubular bag pack, with a casing consisting of a flat, flexible and foldable packaging material, in which the packaging material has a doubling area in which it forms two layers which are connected to one another with the aid of a binding agent, one of the layers in FIG passes over an envelope part, which is connected to a tear-open element, which continues with its beginning into the doubling area.
  • a pack of this type is known from DE-A-1 536188 and is used there in particular for packaging perishable luxury items such as. B. soft cheese.
  • the lumpy packaging material is first wrapped in a sheet of packaging material, which has a sealable and adhesive coating made of an ethylene-vinyl acetate-paraffin wax mixture on the inside, and then the envelope is closed by forming a longitudinal sealing seam and then closed by two transverse sealing seams .
  • Across the packaging material sheet to be used and adhering to the sealable coating there is a tear tape which serves as a tear-open element, which then runs in the packaging envelope next to and along the transverse sealing seam or whose beginning is at one of the two packaging material doubling areas forming transverse sealing seams.
  • the layer of packaging material which merges into the envelope part connected to the tear strips, has a projecting grip tab on the edge of the sealing seam, below which the start of the tear strip is located.
  • This packaging material layer also has pre-slots on both sides of the grip tab that extend into the sealing seam area.
  • a gas-tightness of the sealing medium must also be provided. However, this is not the case in the package described in the aforementioned DE-A because of the paraffin wax-based sealing medium used there. If, however, a sealing medium is used in which the two packaging material layers are connected to one another and a tear strip in the area of the sealing seam in which the opening of the tear organ is located, this sealing seam forms a connection for all parts connected to one another at the same time high mechanical strength. As a result, tearing open the packaging envelope is made considerably more difficult, if not prevented, particularly in the initial region of the tear-open element or tear strip.
  • the invention seeks to remedy this.
  • the invention as characterized in the claims, solves the problem of making the package largely gas-tight in the case of a package with a cover consisting of a flat, flexible and foldable packaging material and with a tear-open element, the beginning of which is at a doubling area of the packaging material to be able and at the same time to facilitate the operation of the tear-open element by simple measures.
  • the tubular bag pack is produced in a manner known per se by the fact that in the packaging machine the continuously tapering packaging material web, which has lines of weakness at predetermined points or a tear tape between two in the longitudinal direction of the web and attached to the sealing layer, in this longitudinal dimension 1 (Fig . 1) around the packaged goods, e.g. B. chocolate bar, folded and formed by forming a (not shown in the figure) longitudinal sealing seam enclosing the packaging material tube sleeve 2, which is divided by transverse sealing seams 3, 3 'and cutting the packaging material at these seams into individual packs.
  • the start of the tear tape is located at the doubling area made of the packaging material layers 4 and 5, which is produced by a transverse sealing seam.
  • the tear tape 7 attached to the inside of the packaging envelope part or the packaging material layer 4 lies between two weakening lines 6 of the packaging material, on which one recognizes the webs 8 between the punched holes and which run parallel to one another over most of the pack, but wedge-shaped apart within the packaging material layer 4.
  • the area delimited in the (upper) packaging material layer 4 by these weakening lines 6 is now opposite in the (lower) packaging material layer 5 by an area 11 which is enclosed by a U-shaped weakening line 12 or the edge 13 of the doubling area .
  • a satin-coated paper web with a basis weight of 60-100 g / m 2 that is coated on one side is used, which is simultaneously provided in a rotary printing machine with surface decor printing and punched punchings along the weakening lines provided on the packaging material.
  • a strip-shaped aluminum foil with a thickness of 0.008 to 0.012 mm is coated on one side with a lamination medium and laminated against the printed and weakened paper web. This composite is finally coated with a cold adhesive on the side facing away from the paper web.
  • a thin polyethylene tape provided with a cold adhesive coating on one side with its cold adhesive-free side is now applied as a tear tape to the packaging material web thus produced.
  • a thermoplastic binder such as, for. B. wax
  • the tear tape is transversely on the packaging material web, i. H. in particular applied perpendicular to their longitudinal extent, for which purpose very complex mechanical engineering measures are required in the packaging machine, which are avoided in the method according to the invention.
  • the packaging material to be used according to this example differs from that described in example 1 in that instead of the paper web a plastic web, in particular a cellophane web with a basis weight of 28-40 g / m 2 , and instead of the cold adhesive coating, a hot melt adhesive coating based on polyethylene is used.
  • a polyester tape which is provided on both sides with a polyethylene hot-melt adhesive coating and is hot-sealed onto the hot-melt adhesive coating of the packaging material, serves as the tear tape.
  • tubular pouch packs are again produced as described with reference to FIG. 1, the sealing seams, in contrast to example 1, being carried out in the form of heat seals.
  • the package according to the invention can primarily be used advantageously as a package for foodstuffs such as chocolates or baked goods that can optionally be made gas-tight or can be produced in the form of tubular pouches.
  • foodstuffs such as chocolates or baked goods that can optionally be made gas-tight or can be produced in the form of tubular pouches.
  • their commercial usability is not limited to packs for solid packaging goods.

Abstract

L'emballage comprend une enveloppe pourvue d'une patte d'arrachement (7) et constituee d'un materiau flexible et pliable. Cette enveloppe comporte un troncon a double epaisseur, dans lequel les deux couches (4, 5) sont collees l'une contre l'autre et ou se trouve l'extremite libre de la patte d'arrachement. Les deux couches et la patte peuvent etre mutuellement solidarisees de facon etanche aux gaz. Pour faciliter l'arrachement de la patte (7) un emplacement de la couche (5) de l'enveloppe qui est en face de la couche (4) a l'endroit ou elle est pourvue de la patte (7), est delimite par des lignes d'affaiblissement (12) de facon a pouvoir etre facilement separe du reste de l'enveloppe lors de l'arrachement de la patte. Pour la fabrication des sachets, la patte d'arrachement (7) est disposee de preference selon la longueur de la bande de materiau d'emballage. Une couche de support comportant les lignes d'affaiblissement obtenues par decoupage est solidarisee avec une couche etanche non perforee de materiau d'emballage.
