Abstract: A method is proposed for producing a packaging, having a method step of microperforation of a flexible material as a packaging film, comprising: provision of the flexible material as a packaging film, transport of the flexible material over a transport section, provision of a laser in order to generate a perforation of the flexible material with its beam. For a packaging with improved gas exchange, a laser system with a wavelength in the range of from 150 nm to 1064 nm, preferably from 355 nm to 532 nm, is used for the laser, and the perforation with the laser is carried out during the movement of the flexible material of the packaging film during the transport.
