Abstract
A packaging container is manufactured through fold forming, vacuum forming, injection molding or other processing to shape a plastically deformable, flexible material, comprising a tubular container body with two longitudinal edges which delimit between them a mainly flat container wall. In order to prevent deformation and/or cracking of the packaging container with normal handling of the side walls, the packaging container is provided with reinforcing elements formed through plastic deformation of the wall material in the region of the longitudinal edges. The reinforcing elements strengthen and stiffen the container and enable it to be conveniently gripped with the hand without the risk of the edges and/or the adjacent side walls being cracked or deformed.
