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.
Claims18
A drawstring bag comprising:
- a first sidewall and a second sidewall, the first sidewall and the second sidewall joined along a first side, a bottom, and a second side, the first sidewall and the second being un-joined along at least a portion of top of the first and second sidewalls thereby defining an opening of the bag;
- a hem located along the opening of the bag in the first sidewall and the second sidewall;
- a drawstring disposed within the hem;
- the drawstring comprising a stretched draw tape film made from an un-stretched draw tape film subjected to a stretching process;
- the stretched draw tape film having an elastic recovery that is greater than an elastic recovery of the un-stretched draw tape film, wherein the elastic recovery of the stretched draw tape film, when the stretched draw tape is in a relaxed state, causes the hem to gather and the opening of the bag to partially constrict;
- and
- the stretched draw tape film having a tensile strength greater than a tensile strength of the un-stretched draw tape film.

A drawstring bag comprising:
- a first sidewall of pliable thermoplastic material;
- a second sidewall of pliable thermoplastic material overlaying and joined to the first sidewall along a first side edge, an opposite second side edge, and a bottom edge extending between the first and second side edges to provide an interior volume, the interior volume accessible by an opening provided by a top edge of the first and second sidewalls;
- a hem formed proximate the top edge of the first and second sidewalls;
- a draw tape positioned in the hem, the draw tape attached to the bag at the first and second side edges and unattached to the bag between the first and second side edges such that the draw tape can expand or stretch freely in the hem;
- and
- the draw tape comprising a stretched draw tape film made from an un-stretched draw tape film subjected to a stretching process that provides the stretched draw tape with an elastic characteristic such that:
- the stretched draw tape film, when in a relaxed state, causes the hem to gather and the opening of the bag to partially constrict;
- and
- the stretched draw tape film has an elastic recovery that is greater than an elastic recovery of the un-stretched draw tape film.
