SYSTEM FOR PRODUCING A PACKAGING LAMINATE, DEVICE FOR PREPARING PACKAGING FOR PACKAGING PRODUCTION, METHOD FOR PRODUCING A PACKAGING LAMINATE AND A PACKAGING PRODUCTION METHOD AND METHOD (10), and a package preparation device and method for producing a package (15, 17). The packaging laminate comprises a layer (6) containing magnetizable particles (19). Failures, such as simple point defects and splices, are marked on the packaging laminate (10) by applying a magnetic field to make a magnetic mark (19) on the packaging laminate. The package preparation device is arranged to detect the presence of the magnetic mark (19) related to a package (15, 17) made of a packaging laminate (10).
