ABSTRACT:
A packing laminate of the type comprising at least two layers of material and at least two converging or intersecting crease lines which assist the conversion of the laminate to a packing container is disclosed. The laminate is provided with at least one auxiliary crease line where the crease lines converge or intersect in order to prevent crack formation in the layers of the laminate and consequent leakage in the container formed therefrom. A method is also disclosed for manufacturing a laminate in which the laminate is provided with auxiliary crease lines after the converging or intersecting crease lines have been provided.
