A thermoplastic bag includes duplicative seals. In particular, in one or more implementations, a thermoplastic bag includes a first seal and at least a second seal reinforcing the same area of the thermoplastic bag. For instance, in one or more implementations, the thermoplastic bag includes multiple seals along each side edge or along the hem. If one seal fails, the other seal(s) can remain in place to prevent leaks. Thus, the duplicative seals of the thermoplastic bag can provide reinforced strength and desired aesthetics.

A 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 provides visual and tactile cues as the films are stretched or elongated. The complex pattern can cause the thermoplastic film to have a low force extension.

Films and bags having low-force extension patterns

A thermoplastic film which embodies a three-dimensional pattern. The thermoplastic film comprises a three-dimensional pattern including at least three sub-patterns of deformations. The shape, positioning, and pattern deformation density of the at least three sub-patterns of deformations cause the three-dimensional pattern to give the thermoplastic film a thicker appearance.

Films and bags having three dimensional patterns

Thermoplastic films and bags include gradient patterns of post-formation deformations. The gradient patterns of post-formation deformations can provide a connotation of strength. Additionally, the gradient pattern of post-formation deformations can provide different areas of the films or bags with different physical characteristics such as tear resistance, puncture resistance, elasticity, etc.

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.
