Abstract
In a package, especially a pouch package, with a covering made of a flat foldable packaging material in which the inner sides of two strip-like edge regions are sealed together in a joining region to form the covering, there is a strip-like tear region in the package covering which starts from one of the two strip-like edge regions, extends substantially prependicularly thereto and has notches or linear punched-out regions only within the strip-like edge region. Here, at the beginning of the rear region between the two strip-like edge regions, there is a tab of flat material which is firmly secured to the edge region from which the tear region starts and is secured detachably or not at all to the other edge region, while the remainder of the flat of the tab projects beyond the edge of the edge region.
