The invention relates to a tear-up opening arrangement for a packing container which is manufactured from a plane packing material web by folding, the packing material being pierced through along a line (6) which is situated alongside or in the vicinity of the base line of a sealing fin (10) projecting from the packing container. The said cut line is covered along the inside of the packing container by a thin, molecular-oriented plastic strip (7) whose direction of orientation coincides with the extension of the cut line. |
