Definitions

  • the invention relates to a tubular bag pack according to the preamble of claim 1.
  • Tubular packs of this type are from the EP-A-399420 and DE-U-90 04 904 known.
  • a connection-free one in each edge zone Area provided both are arranged one above the other while the U-shaped Punching with part of the limitation of this Areas matches.
  • a disadvantage is that even with a slight contradiction of the two stripe-shaped edge zones in the manufacturing process the U-shaped punching in the connection area falls, making opening difficult becomes.
  • the pull tab, the beginning of which is the U-shaped punching is limited, not easy to start.
  • this packaging material consists of a 0.015 to 0.20 mm thick biaxially stretched polypropylene film (OPP film), a 0.007 to 0.009 mm thick, printed aluminum film, a paper with a grammage of 30 to 100 g / m 2 and a latex-based cold adhesive coating applied in the profile (2 to 7 g / m 2 solid).
  • OPP film gives the composite mechanical strength
  • the paper forms the carrier layer of the composite material and the aluminum foil the layer that ensures the gas tightness of the composite.
  • Fig. 1 now shows schematically in perspective Representation of a manufactured in this way Flow pack for waffles.
  • the Edge zone 2 coming to the outside is included wider than the edge zone 3, so that between the edge 4 and the connection area 1 in the edge zone 2 connection-free area 5 remains, which over the edge zone 3 lying below extends.
  • the U-shaped Punching 6 provided with the ends 7 of their Leg extends into the connection area 1.
  • connection-free area 5 of the edge zone 2 forms the packaging material within the U-shaped Punching 6 a grip tab 8, the Beginning of a "virtual" striped tear area 9 with mutually parallel boundary lines 10 forms.
  • the grip tab is in Pulled in the direction of arrow 11, which Packaging material with suitable selection at the ends 7 the U-shaped punching approximately along the imaginary lines 10 tears.
  • Fig. 2 shows the tubular bag pack in the Supervision in a partial representation, with the U-shaped punching partially covers the packaging is shown broken.
  • the Tubular bag pack after or during application the U-shaped punching in the packaging material web an area of packaging material that is covered on three sides by this punching, on the surface of the pack Side of the packaging material by 180 ° folded outwards.
  • This folding is particularly stable, though the multilayer packaging material used contains an aluminum foil. The feature of this folding is not shown in Figures 1 and 2.
  • Multi-layer packaging materials used in the tubular bag pack according to the invention Tear the opening process further along parallel lines, are in the published international patent application WO 91/06488.
  • the tubular bag pack according to the invention is primarily used as a pack for foods like Chocolates or baked goods are used.
