A container for consumer articles is at least partially formed from a laminar blank having an inner surface and an outer surface, and a thickness (T) of from about 100 micrometers to about 350 micrometers. The laminar blank defines a portion of the container that comprises a first planar wall and a second planar wall connected to one another by a first edge portion. The inner surface of the first edge portion comprises one or more ablated lines extending substantially in the longitudinal direction of the first edge portion, each of which is provided as a groove within the blank, having a minimum residual thickness (RT) of from about 15 percent to about 40 percent of the thickness (T) of the laminar blank, and an ablated width (X) as measured transversely to the longitudinal direction of the first edge portion. The laminar blank is folded about the one or more ablated lines such that, for each ablated line, the angle (a) between the outer surface of a first planar portion of the blank adjacent to one side of the ablated line and the outer surface of second planar portion of the blank adjacent to the other side of said ablated line, is within 5 degrees of: |
