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.

Abstract translation: 提供了一种塑料袋，其包括活性弹性带，其在弹性带的正常状态下收缩，从而收缩袋的开口以帮助将袋保持在物体上。 弹性带包括在袋的第一侧边缘和第二侧边缘之间连续地附接到袋的侧壁的第一区域和保持未连接到侧壁的第二区域。 附着区域不收缩，而是将其附着到其侧壁的侧壁的部分压向蛇形路径。 未附着的区域确实收缩，使得与其相邻的侧壁的部分聚集在一起。 还提供了一种用于制造塑料袋的方法，该方法涉及拉伸带状弹性带并将拉伸的带的区域连续地附着到塑料材料的卷材上。
