Claim:
1. 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.
