Abstract
An opening arrangement on packing containers is provided with thermoplastic layers, which in general are present on both sides of packing laminate and extend past a cut edge and are sealed in a liquid-tight manner to each other. This can be achieved simplest if the hole-punching of the carrier layer of the material is done prior to the application of the thermoplastic layers.
