Abstract
The plastic bag with a hem and draw tape may include flexible thermoplastic sidewalls that have a network pattern imparted onto them across the side seams. In one embodiment, the network pattern is below the hem seal. In another embodiment, the network pattern covers the hem seal. The bag may also include a ribbed pattern below the network pattern. The network pattern may be continuous or discontinuous.
Claims21
A thermoplastic bag comprising:
- a first sidewall of flexible thermoplastic material;
- a second sidewall of flexible thermoplastic material overlaying and joined to the first sidewall to form a first sidewall seam along a first side edge, to form a second sidewall seam along an opposite second side edge, and a closed bottom edge, the first and second sidewalls un-joined along respective top edges to define an opening opposite the bottom edge for accessing the interior volume;
- the sidewalls forming a hem having a top length and extending along the open top end disposed opposite the bottom edge, the hem having a bottom length and a hem seal, the hem including one or more draw tape notches and a draw tape within the hem;
- wherein the first and second sidewalls include a first portion with a raised, embossed, discontinuous network pattern extending linearly between the first side edge and the second side edge;
- wherein the discontinuous network pattern consists of multiple raised icons separated by smooth, unraised areas across the width of the bag;
- wherein the network pattern provides texture with no additional overall stretching;
- wherein the portion with the discontinuous network pattern extends from above the bottom edge to below the hem seal such that there is a top un-patterned portion below the hem seal;
- wherein the bag comprises a second stretched portion with a pattern of adjacent, linear ribs extending linearly between the first side edge and the second side edge, the ribs being substantially parallel and wherein the second portion is below the first portion.
