    Abstract: A method for the production of a film for tear-open packagings having a weakening line. A film web having at least one film layer of a thermoplastic plastic is passed to a hot-embossing device, in which the film web is provided with a line-shaped embossing. The film web is then passed to a laser beam device, in which the film web is provided with a line-shaped laser seam. The embossing and the laser seam cover each other and jointly form the weakening line.
