Abstract
One or more implementations of a thermoplastic bag with a grab zone of deformations including raised rib-like elements positioned in a high-touch area of the bag. For example, the thermoplastic bag includes a hem skirt non-continuously laminated to a sidewall by one or more raised rib-like elements. The grab zone regions of one or more raised-rib-like elements are located in visible and high-touch areas to provide visual and tactile cues of strength and durability. Moreover, the grab zone regions of one or more raised rib-like elements serve to distribute pull and lift forces across a wider area in order to avoid common failures in high-touch areas such as over stretching, punctures, tears, and rips.
Claims17
A thermoplastic bag comprising:
- opposing thermoplastic film sidewalls each comprising:
- a folded over top portion extending down an inner surface of the thermoplastic bag and forming a hem channel;
- a hem skirt extending from the hem channel toward a bottom of the thermoplastic bag;
- and
- a region comprising a plurality of raised rib-like elements in a strainable network and devoid of contact areas, the plurality of raised rib-like elements bonding the hem skirt to the inner surface of the thermoplastic bag and providing the region with increased elasticity compared to portions of the thermoplastic film sidewall lacking the plurality of raised rib-like elements;
- wherein each plurality of raised rib-like elements is configured to cause one of the hem skirts to separate from the respective thermoplastic film sidewall before the respective thermoplastic film sidewall fails when subjected to a force.
A multi-film thermoplastic bag comprising:
- first and second opposing sidewalls joined together along a first side edge, an opposite second side edge, and a closed bottom edge;
- a hem channel extending along a top edge of each of the first and second opposing sidewalls;
- and
- a respective hem skirt extending down an inner surface of each of the first and second opposing sidewalls of the multi-film thermoplastic bag from the respective hem channel toward the closed bottom edge;
- and
- a region comprising a plurality of raised rib-like elements in a strainable network and devoid of contact areas, the plurality of raised rib-like elements bonding the hem skirt to the inner surface of the multi-film thermoplastic bag and providing the region with increased elasticity compared to portions of the multi-film thermoplastic bag lacking the plurality of raised rib-like elements.
