Zusammenfassung: | The invention relates to a film-type packaging material comprising at least one processing layer (2) and at least one barrier layer (3) which are planarly joined to each other so as to form the film-type packaging material (1), at least one additional layer (6) being placed between the processing layer (2) and the barrier layer (3). The additional layer (6) contains a material which reflects and/or diffracts a laser beam (5), thus reducing the energy which impacts the barrier layer (3) and is generated by a layer beam (5) introduced via the processing layer (2). |
