  • the container is suitable for printing or applying an imprint in a simple manner, There are a number of ways to attach the imprint on one or more of them several layers of material.
  • the flatness of the blank makes it easy to process and transport.
  • the tightness of the container is when filling the appropriate food important, because both during filling and during subsequent transport no penetration or Ausdringen a corresponding fluid is to be feared.
  • the container both in terms of deeper and also higher temperatures in terms of its properties and shape is resistant. That is, for example, a food is filled and then cooled properties such as tightness, flexibility, dimensional stability, Change transparency or the like. This applies analogously to elevated temperatures, the For example, for sterilizing the container are beneficial. Also, you can do it accordingly High temperatures also occur if the container is to be consumed heated food is used.
  • the viewing windows allow insight into the container interior and are in optically more advantageous Way in different shapes and with different numbers anordbar.
