The disclosure relates to a method in the forming of packaging containers (1) which have sealing fins in which the packaging material is sealed inside-to-inside, and also projecting, double-walled corner flaps (8). In order to form a parallelepipedic packaging container, the corner flaps are folded down and sealed to the outside of the packaging container, which subjects a sealing fin running between the corner flaps to stresses which may entail untightness in the packaging container. This is avoided in that the sealing fin, prior to the downward folding operation, is deformed in that at least a portion of the fin (4) is laterally displaced in relation to adjacent portions of the fin. |
