FOLDING BOX PACKAGE OF A LIQUID-TIGHT, HEAT SEALABLY COATED COMPOSITE CARDBOARD MATERIAL, MORE PARTICULARLY A FOIL MOUNTED COMPOSITE CARDBOARD MATERIAL

摘要

The invention relates to a folding box of composite cardboard material coated heat sealably at least on the inside, which has a flat bottom to which two pairs of opposite triangular folding pockets are sealed lying flat. To prevent bubble formation on the inside of the package, more particularly those areas of the triangular folding pockets which are to be sealed to one another over their complete surface, due to steam forming in the composite cardboard material during the heat activation of the areas, the heat sealable coating is perforated right into the cardboard in the areas.
