Definitions

  • the invention relates to a packaging bag made of a multilayer, film-shaped and flexible composite material, wherein one of the layers one in has significant linear weakening as an integrated tear-open aid.
  • EP-A 0 807 587 describes a packaging bag made of a multilayer, known film-shaped and flexible composite material.
  • One of the layers points an essentially linear weakening as an integrated tear-open aid.
  • the area of weakening is in the form of a film-forming mass Printing covered with lacquer colors.
  • the weakening is in the marginal area the packaging is placed over the contents of the bag.
  • To remove the contents of the bag the film-forming mass is broken up by a pulling or kinking movement causing the pouch to open in the weakened area.
  • the invention has for its object a packaging bag of the beginning to create the type mentioned, which occurs when the contents of the bag break opens in two parts at the same time and easy removal of the two Parts without additional opening manipulations.
  • the weaken weak layer adjacent layer easily and thus a problem Allow opening of the pouch.
  • the composite material leads to the achievement of the object according to the invention a layer forming the outside of the bag and containing the weakening a transparent or opaque plastic film or paper and either an aluminum foil bonded to the plastic film or paper and a sealing layer connected to the aluminum foil and forming the inside of the bag, or one associated with the plastic film or paper that Has polymer resin extrusion layer forming the inside of the bag.
  • the plastic film or paper containing the weakening can be printed his. If the printed side forms the outside of the bag, then the printing is expediently provided with a protective lacquer.
  • the plastic film or the paper with the aluminum foil is preferably over an adhesive layer connected.
  • the material for the plastic film containing the weakening is preferred oriented polypropylene (OPP), polyethylene (PE), especially polyethylene high density (PEHD), polystyrene (PS) or polylactate (PLA).
  • OPP oriented polypropylene
  • PE polyethylene
  • PEHD polyethylene high density
  • PS polystyrene
  • PLA polylactate
  • a preferred embodiment of the weakening is an essentially linear one Perforation or a complete cut, with the Weakness essentially over an entire scope or even only over can extend part of the circumference of the bag.
  • the weakening is preferably essentially in the middle between two edge areas of the bag above the The inner edge of the bag is arranged so that the weakening of the packaging bag to lie essentially above the predetermined breaking point of the contents of the bag comes.
  • the packaging bag according to the invention can be used as a flat bag, a sealed edge bag, Space bags or tubular bags can be designed. However, are preferred Tubular bags, which are terminated by transverse sealing seams and, if necessary distinguish a longitudinal seal seam, and sealed edge bags with each two cross and longitudinal sealed seams.
  • the weakening can prove expedient not only essentially in the middle between two sealing edge areas to provide the bag over the bag interior, but also in the Seal the edges. So that after breaking the contents of the bag formed two bag parts can be easily separated from each other if necessary.
  • the weakenings can be on one or both of the through the sealing edges limited bag sides can be arranged.
  • a preferred use of the packaging bag according to the invention lies in the packaging of solid foods such as chocolate bars, Biscuits and chocolate covered bars and biscuits.
  • the composite material 10 In the production of the composite material 10, it is first used as a print carrier serving opaque or transparent plastic film or the paper 14 printed and simultaneously with the desired lines of weakness 22 in the form of material cuts Mistake.
  • the cutting arrangement is via print marks precisely controlled.
  • the so printed and provided with the weaknesses 22 Plastic film or paper 14 is subsequently coated with the protective lacquer 11 provided, which is applied to the printing 12.
  • the aluminum foil 18 is on one side with the sealing layer 20 and on the the other side with the adhesive layer 16. Then the with the aluminum layer 18 provided with the sealing layer 20 over the adhesive layer 16 with the printed and protective lacquered plastic film or paper 14 for Composite material 10 glued with integrated tear aid.
  • the printing 12 with the protective lacquer layer 11 forms the later outside 24, the sealing layer 20 applied to the aluminum foil 18 the inside 26 of a packaging bag made from the composite material 10.
  • the second embodiment of a composite material 10 shown in FIG. 2 differs from the first embodiment shown in FIG. that the plastic film 14a is transparent and the printing 12 in Inside the composite material 10. With this variant there is no protective lacquer layer for printing.
  • the transparent plastic film 14a against the one with the adhesive layer 16 provided aluminum foil 18 glued the printing 12th the adhesive layer 16 is present.
  • the transparent forms Plastic film 14a, the outside 24 and the sealing layer 20 on the Aluminum foil 18, the inside 26 of one made from the composite material 10 Packaging bag.
  • a polymer resin extrusion layer which also serves as the sealing layer 20 and has a weight per unit area of 2.0 to 15.0 g / m 2 can be applied directly to the printing 12 of the plastic film 14a be applied.
  • a sealed edge pouch shown in FIG. 3 made from the composite material 10 28 is provided with a circumferential sealing edge 30.
  • the front and The back of the sealed edge bag 28 usually consists of the same Composite material 10, with the exception of the printing, which is different on both sides can be.
  • the weakening 22 is on the front of the sealed edge bag 28 in the middle between two opposing sealing edges 30a, b and parallel to this as a complete cut of the Plastic film or paper arranged.
  • the weakening 22 ends in one Distance a to the other two sealing edges 30c, d.
  • the severing of the plastic film comprises or the area of the other two sealing edges 30c, d.
  • the tubular bag 38 shown in Fig. 5 has on its front in the Center between the two transverse sealing seams 34 and parallel to them Weakening 22 on.
  • Attenuation 22 is the contour of a biscuit packaged in the bag 42 indicated.
  • the biscuit 42 has a notch 44 as a predetermined breaking line.
  • This Notch 44 runs essentially parallel to the likewise line-shaped Weakening 22.
  • the tubular bag 38 tears open along the weakening 22.
  • This separation of the composite material 10 on the front of the tubular bag 38 leads the two ends of the weakening 22 to a further opening of the bag along a tear line 40, which varies depending on the intensity of the tear process 7 to the back of the tubular bag 38, in extreme cases up to to the longitudinal seal seam 36, can continue.
  • FIG. 8 shows the opened tubular bag 38 after the biscuit 42 is along its predetermined breaking line 44 has been broken into two parts 42a, b.
  • the Tubular bag 38 is simultaneously made into approximately two equal sized partial bags 38a, b separated.
  • the two bag parts 38a, b are opened so far that the two biscuit parts 42a, b easily pushed out of the partial bags or can be pulled out.
  • the weakening 22 also extends to the area of the longitudinal sealing seam 36 extends, as in an analogous manner with the sealed edge bag shown in FIG. 3 28 is the case.
