  • Especially preferred thicknesses of the bottom web lie in the range of 500 to 650 ⁇ , wherein cup-shaped boxes made of a bottom web consisting of a compact thermoplastic film preferably have a thickness of between 500 to 600 ⁇ and cup-shaped boxes made of a bottom web consisting of a foamed thermoplastic film preferably have a thickness of between 500 to 650 ⁇ .
  • the rigidity of the cup-shaped container for providing a sufficient stackability of the container is measured by the maximum top load vertically applied to the upper rim or the top surface of the flange of the cup-shaped container when decreasing the height of the container by 3 mm.
  • This top load is the maximum force that can be applied to the upper rim or the top surface of the flange of the container when the container is vertically compressed by 3 mm.
  • the top load is a force as the pressure depends on the surface of the cup rim or the top surface of flange.

  • the thickness of the jacket and that of the bottom of a cup-shaped box, or the thickness of a possible flange formed to the upper rim of the jacket may differ to some extent, because said boxes are usually formed by thermoforming resulting in a box whose bottom and a possible flange are usually thicker than the thickness of the jacket.

  • the sealing layer is preferably a continuous layer. Hot melt layers have preferably a mass per unit area of 6 to 16 g/m 2 .
  • Cups known in the prior art usually have a gap between the top of the banderole and the top of the box, because otherwise when using a standard banderole of 95 g/m 2 the banderole may be wrinkled at its top.
  • the inventive container requires a banderole of a certain thickness to ensure a sufficient load capacity (stackability). That is why a banderole that extends up to the top of the jacket or up to the lower surface of a possible flange molded to the upper edge of the jacket may be preferred.
