Abstract
The bag may include a draw tape that may be used to cinch closed the opening of the bag. The draw tape has at least one stretched elastomeric strip attached to the draw tape in an extended condition. The draw tape may be smaller in size than the bag sidewalls. The draw tape may include an elastic characteristic, such as patterned ribs. In one embodiment, the roll of bag is kept under tension to maintain the elastomeric strips in a stretched condition.
Claims20
A draw tape bag comprising:
- a first sidewall;
- a second sidewall, the second sidewall joined to the first sidewall by a closed bottom end, a first edge, and a second edge, thereby defining an opening of the draw tape bag at a top end;
- the first and second sidewalls forming a hem having a top length and extending along the open top end disposed opposite the bottom end having a bottom length, the hem including one or more draw tape notches;
- and
- a flat pliable thermoplastic draw tape in an extended state housed within the hem, the flat pliable thermoplastic draw tape having an elastic characteristic that allows the flat pliable thermoplastic draw tape to expand and contract along a length of the flat pliable thermoplastic draw tape when subjected to loads consistent with insertion of the draw tape bag into a receptacle;
- wherein the flat pliable thermoplastic draw tape is attached to the first and second sidewalls at a side seal and wherein the flat pliable thermoplastic draw tape, when in a relaxed state, causes the hem to gather and the opening of the draw tape bag to partially constrict;
- wherein the flat pliable thermoplastic draw tape is formed by stretching an initial pliable thermoplastic draw tape, and wherein the elastic characteristic of the flat pliable thermoplastic draw tape is greater than an elastic characteristic of the initial pliable thermoplastic draw tape.

A draw tape bag, comprising:
- a pair of pliable thermoplastic body panels joined to each other along a pair of opposing sides and a bottom bridging the opposing sides, the body panels forming a hem extending along a mouth end disposed opposite the bottom, the hem including one or more draw tape notches;
- and
- a flat pliable thermoplastic draw tape housed within the hem and being sealed together with the hem at least one side seal of the bag, the draw tape being partially exposed by the respective draw tape notches which allow the draw tape to be pulled therethrough to close the draw tape bag and to be used as a handle, the flat pliable thermoplastic draw tape having an elastic characteristic that allows the flat pliable thermoplastic draw tape to expand and contract along a length of the flat pliable thermoplastic draw tape when subjected to loads consistent with insertion of the draw tape bag into a receptacle, wherein the flat pliable thermoplastic draw tape is attached to the opposing sides of the thermoplastic body panels and wherein the flat pliable thermoplastic draw tape, when in a relaxed state, causes the hem to gather and an opening of the draw tape bag to partially constrict;
- wherein the flat pliable thermoplastic draw tape is formed by stretching an initial pliable thermoplastic draw tape, and wherein the elastic characteristic of the flat pliable thermoplastic draw tape is greater than an elastic characteristic of the initial pliable thermoplastic draw tape.
