ABSTRACT:
A tear-up opening arrangement for a packing container which is manufactured from a plane packing material web by folding is disclosed. The packing material is pierced through along a cut line which is situated alongside or in the vicinity of a base line of a sealing fin projecting from the packing container. The cut line is covered along the inside of the packing container by a thin, molecular-oriented plastic strip whose direction of orientation coincides with the extension of the cut line. The cut line has two end portions extending on either side of the apex of a triangular lug of the container and a center portion extending parallel to, but at a distance from, a line through the apex and the end portions.
