ABSTRACT:
Provided is a plastic bag including a live elastic strip that, in the elastic strip's normal condition, contracts thereby constricting an opening of the bag to assist in retaining the bag to an object. The elastic strip includes a first region that is continuously attached to a sidewall of the bag between a first side edge and a second side edge of the bag and a second region that remains unattached to the sidewall. The attached region does not contract but instead forces the portion of the sidewall to which it is attached to pucker into a serpentine path. The unattached region does contract causing the portion of the sidewall to which it is adjacent to bunch together. Also provided is a method for manufacturing a plastic bag that involves stretching a live elastic tape and continuously attaching a region of the stretched tape to a web of plastic material.
