Definitions

  • the invention relates to a packaging container, in particular a bag packaging, containing at least two wall foils separated by the filling material when ready for sale, at least one peelable or peelable near the edge connecting two wall foils Connecting seam, a packaging edge running along the connecting seam, and a recess penetrating the connecting seam vertically.
  • a packaging container in particular a bag packaging, containing at least two wall foils separated by the filling material when ready for sale, at least one peelable or peelable near the edge connecting two wall foils Connecting seam, a packaging edge running along the connecting seam, and a recess penetrating the connecting seam vertically.

  • Such a package is opened by the front and back packaging films or wall foils in their area close to the connection by one hand with the thumb and index finger grasped and pulled apart with force until the The peelable seam close to the edge begins to open or peel along the length and separating the front and rear wall foils in the area of the connecting seam go. This is by far the most common way to open such packages, since no tools are required and the time required to open it is less, and since there are no cut-off small parts as packaging waste.
  • Packs of the type described must be in the shops either on rack boards are stored or they are in special tools, such as brackets, in hung on the shelves and racks. So on such additional tools for hanging the bag packs can be dispensed with, the packs are usually in the Area of the upper, near-edge, peelable connecting seam with a parallel to this Seamless recess or slot, for example with the so-called Euro slot Mistake. This allows the packaging to be hung on bars on shelves, for example.
