ABSTRACT:
A parallelepipedal gable-topped bulk-material container made out of a multilayer plastic laminate and with its head sealed by a ridged seam, leaving two superimposed triangular folding tabs at the ends of the seam, whereby each tab is wrapped out and around a straight buckling edge on each side of the container and the container material has longitudinal and transverse or sloping scores for the edges of the body and floor or gable edges. To maintain the integrity of a ridged seam when manufacturing and sealing thick-walled containers in a filling machine and hence eliminate ridged-seam fracture, the container has at least one auxiliary score for each vertical body score in the vicinity of the gable and out of alignment with the body score.
