ABSTRACT OF THE DISCLOSURE A packing laminate in the form of a web with thinned edge zones is manufactured by providing a wide raw material web simultaneous1y with a number of parallel thin- ned areas. The raw material web is then covered with layers of thermoplastic material, whereupon it is divided into webs of the desired width by means of cuts placed asymmetrically in the said thickness-reduced areas. As a result the finished laminate webs obtain thermoplastic-covered, thickness-reduced edge zones of different widths.
