<p>The present invention describes an improved metallic roller for modifying the structure of flexible laminations and substrates, said roller strategically comprising abrasive surfaces for mechanically modifying the structure of such laminations and substrates. The invention also includes a roller press, which includes the aforementioned roller, intended to produce micro perforations in the substrates and laminations by means of the roller pressure. The invention also refers to a method for modifying the structure of substrates and laminations. On the other hand, the invention comprises flexible substrates and laminations with a mechanically modified structure, and the packings manufactured with these flexible laminations and substrates.</p> |
