Discontinuously laminated film structures with improved visual characteristics

摘要

In one example embodiment, a laminated film includes an extruded ribbed first film portion that includes multiple ribs, where consecutive ribs are separated by webs that are integral with the ribs. The laminated film also includes an un-ribbed second film portion, and a region of discontinuous lamination between the first film portion and the second film portion. The region of discontinuous lamination includes multiple regions where the first and second film portions are bonded together, and multiple regions where the first and second film portions are not bonded together.

主权项

1. A laminated film, comprising:
a first film that includes a plurality of extruded ribs, wherein consecutive extruded ribs are separated by webs that are integral with the extruded ribs, wherein the first film includes a plurality of thinner stretched linear areas that alternate with a plurality of thicker linear areas, wherein the thinner stretched linear areas and the thicker linear areas are formed in the webs and extruded ribs of the first film; a second film that is devoid of extruded ribs; and discontinuous lamination between the first film and the second film, the discontinuous lamination comprising:
a plurality of regions where the first and second films are bonded together; anda plurality of regions where the first and second films are not bonded together.
