In a sealing machine a pair of juxtaposed foils are sealed together at web regions having oppositely directed outer surfaces between a pair of dies, at least one of which is formed with an array of bumps that taper outwardly toward a respective one of the outer surfaces. The bumps press into the one outer surface and form therein permanent cavities of a predetermined imprint depth so as to bond together the foils at the web region. A quality of seal is determined by measuring after formation of the cavities surface features of the cavities at a level of the one outer surface of the respective foil, and calculating based on the measured surface features an imprint depth of the cavity.

Quality-control method for laminated-foil packaging system

A method for process control and documentation in a boxing machine for individual packages each having an individual package transponder and wherein the individual packages are stacked and the box is provided with a transponder as well. A writing unit writes information with respect to the individual packages to the respective individual package transponders and a reading unit for the transponders serves to control subsequent packaging operations. The operations are also documented on the box transponder.
