摘要:
A method for making apertures in a precursor web using a forming apparatus is provided where the web comprises a film having molecular orientation and the forming apparatus comprises an arrangement of teeth. The orientation of the arrangement of teeth and the molecular orientation of the film are predetermined and modified to provide a relative angle between the orientation of the teeth and the molecular orientation of the film. Apertures formed in the precursor web material have a length and width exhibiting a minimal aspect ratio.
