摘要：
A system and a method for production of a packaging laminate that comprises a layer containing magnetizable particles. The method involves marking faults, such as single spot defects and splices, on the packaging laminate by the application of a magnetic field to make a magnetic mark on the packaging laminate. A packaging device is arranged to sense the presence of the magnetic mark related to a package made from the packaging laminate.
