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.
Claims20
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;
- at least one of 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 at least one of the first or second sidewalls includes a first portion with a continuous network pattern comprising rib-like elements extending:
- linearly between the first side edge and the second side edge in a direction perpendicular to the first side edge and the second side edge;
- across the first and second sidewall seams;
- and
- below the hem seal;
- and
- 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 in the direction perpendicular to the first side edge and the second side edge, the ribs being substantially parallel and extending from the first side edge to the second side edge and wherein the second portion is below the first portion.

A thermoplastic bag comprising:
- a first sidewall of flexible thermoplastic material, the first side wall comprising a first portion extending from a hem toward a bottom edge and a second portion positioned between the bottom edge and the first portion;
- a second sidewall of flexible thermoplastic material overlaying and joined to the first sidewall by a first sidewall seam along a first side edge, by a second sidewall seam along an opposite second side edge, and a closed bottom edge, wherein the first and second sidewalls are un-joined along at least a portion of respective top edges to define an opening opposite the bottom edge for accessing an interior volume of the thermoplastic bag;
- the hem enclosing a draw tape;
- a strainable network of rib-like elements in the first portion, the rib-like elements extending linearly between the first side edge and the second side edge in a direction perpendicular to the first side edge and the second side edge;
- and
- a plurality of ribs in the second portion extending linearly between the first side edge and the second side edge in the direction perpendicular to the first side edge and the second side edge, the ribs being substantially parallel and extending from the first side edge to the second side edge.
