Definitions

  • the invention relates to a packaging made of flexible material, with a longitudinal seam and two transverse seams designed as fin seams.
  • Such packaging is known from DE-GM 85 16 067.
  • the transverse seam is closed with cold glue.
  • the cold adhesive connection is released by pulling on the fin of the longitudinal seam, so that the contents can be removed in whole or in part via this opening.
  • the invention has for its object to design a packaging of the type mentioned so that a clean defined opening can be achieved, which is easy to reseal after removing a portion of the contents.
  • the flexible material contains at least one layer of a monoaxially oriented plastic film, the orientation of which extends in the direction of the longitudinal seam of the packaging, and that two tear notches are provided on a transverse seam, which are spaced apart on different sides of the longitudinal seam are.
  • the packaging tears at the tear notches the transverse seam opens between the tear notches and the top part of the packaging becomes a strip, the width of which is the distance corresponds to the two tear notches, cleanly separated.
  • the holding force of the transverse seam is set at least in the area between the two tear notches in such a way that it is sufficiently tight but at the same time can be easily pulled open.
  • Figures 1 to 5 show a packaging of a chocolate bar in different opening stages.
  • Fig. 1 denotes a packaging which consists of flexible material and has a longitudinal seam 2 and two transverse seams 3 and 4, all of which are designed as fin seams, i.e. the inside of the packaging sections are sealed or glued to each other.
  • the flexible material has at least one layer made of a monoaxially oriented plastic film, the orientation of which - indicated by the arrow 5 - runs in the direction of the longitudinal seam 2.
  • an elongated polypropylene film with a thickness of 35 micrometers was used as the monoaxial plastic film, which was laminated to the outside with an aluminum film of 12 micrometers and paper of 70 g / m 2.
  • the outstanding splicability of the monoaxially stretched PP film (PPF) was retained for the entire flexible material composite.
  • a 35 micron thick PPF film was also used as the middle layer, to which an aluminum film of 7 micron thickness was attached on the inside and paper of 50 g / m 2 on the outside.
  • the appropriate film and the other layers of the laminate are selected. Combinations of several plastic films are also conceivable, with which transparent packaging can be achieved.
  • the thickness of the monoaxially oriented plastic film is in the range from 10 to 300 micrometers and depends on the requirements of the goods to be packaged and the other laminate layers.
  • two tear notches 6 and 7 are punched out on the free edge of the transverse seam 3 and are arranged on both sides of the longitudinal seam 2.
  • the fin of the longitudinal seam 2 is grasped and pulled upwards (FIG. 2).
  • the tear force is evenly distributed over the two tear grooves and the transverse seam is drawn in the area between the tear grooves.
  • the strip of the upper packaging part lying between the two tear notches is deliberately separated out as it is pulled along along two straight lines and the contents are exposed in this section.
