Abstract
A tubular pouch is provided with a tear-open strip which begins at a U-shaped perforation formed in one of two edge strips of the pouch which are joined across a junction area by cold-sealing into tubular pouch fins. The U-shaped perforation defines a grip formed by the wrapping material inside it and includes legs extending toward and entering the junction area. However, in its remaining portion, the U-shaped perforation does not reach as far as the junction area and thereby manufacturing tolerances relating to the U-shaped perforation and the relief cold bondings as well as lateral shifts between the two edge strips cannot result in bonding of the grip. When the grip is pulled to open the wrap, the wrapping material tears from the ends of the perforation along approximately parallel lines. The grip can be advantageously folded over 180.degree. in order to be readily grasped.
