Abstract

Disclosed is a packaging for piece goods having a folded shell made of cellulose-containing flat material. The shell and a cover enclose an interior of the packaging. The shell has a first side wall, on which a first sealing rim is angled outwardly away from the interior along a first fold edge. The cover is glued to the first sealing rim. The packaging has a perforation for tearing off the first sealing rim together with the portion of the cover glued to it from the first side wall on the first fold edge. Also disclosed is a method for opening a packaging which also has a second side wall, on which a second sealing rim is angled outwardly away from the interior along a second fold edge, with the cover being glued to the first sealing rim and to the second sealing rim.
