  • Films and bags with billow pockets for capturing liquids
    Patent number: 11535002
    Abstract: A multiple-ply thermoplastic film which exhibits elastic-like behavior along at least one axis when stretched or elongated and then released. The thermoplastic film comprises a plurality of raised rib-like elements extending in a direction perpendicular to a main surface of the thermoplastic film. The thermoplastic film further includes a plurality of web areas positioned about the plurality of raised rib-like elements. The plurality of raised rib-like elements and plurality of web areas are arranged in a complex pattern. The complex pattern, when stretched or elongated and then released, can cause areas of billowing and delamination between plies of the multiple-ply thermoplastic film. The resulting billowed and delaminated areas form billow pockets for capturing liquids that can capture liquids when one of the plies is punctured.
