Claim:
A product comprising: a film comprising a thermoplastic polymer material or an assembly of films, each film comprising a thermoplastic polymer material, all of the films include: an array of parallel band-shaped, linearly extending regions (A) and distinct linearly extending webs (B) integrally connecting the regions (A), each web (B) along its linear extension is thinner than adjacent portions of the regions (A), and where the regions (A) and the webs (B) are oriented having at each location a dominating direction of orientation, where each of the dominating directions of orientation of the regions (A) forms an angle (v) with a direction in which the regions (A) extend, where the angle (v) has a value greater than 0° and less than or equal to 80°, where the webs (B) includes arrays of linear furrows (C), where the furrows (C) comprise necking-down zones or splits, where each of the furrows (C) forms an angle (u) with the directions in which the regions (A) extend, and where the angle (u) has a value greater than the value of the angle (v).
