The invention relates to an apparatus (1) for making perforations in a packaging material, in particular a polymer film (2), comprising a conveyor for transporting the material (2) along a path through the apparatus (1), a laser device (7) with adjustable focal point, and an in-line optical detector (8) for measuring one or more parameters of the perforations made with the beam. The apparatus further comprises a support (12) for supporting the packaging material (2) at or near the position of the laser (7) and/or the detector (8). The support (12) comprises a recess or an opening (16) in the support receiving the beam of the laser (7) and/or providing optical access to the packaging material (2) from both sides.
