Abstract

The invention relates to a method for producing a perforated film (1), wherein a film body (2) is produced from a plastic melt, in which film body (2) slits (6) and/or thin points are made, or which film body (2) is produced at least approximately in a lattice-shaped manner or is provided with a lattice-shaped structure, and subsequently the film body (2) is stretched, in particular biaxially in a longitudinal direction and in a transverse direction, to produce a structure with longitudinal slats (3) which are connected to one another by transverse slats (4), with the formation of apertures (5), wherein the proportion of the material of the plastic is distributed non-uniformly to the longitudinal direction and the transverse direction of the film body (2). Furthermore, the invention relates to a corresponding perforated film.
