Abstract: A packaging has juxtaposed front and rear panels having juxtaposed upper and lower end edges and juxtaposed side edges extending between ends of the end edges. The side edges are fastened together to define an interior space between the panels. A plurality of longitudinally extending weakened tear lines are formed in and extend along a full longitudinal length of each of the panels. Respective upper and lower transversely extending welds extend along and secure together the upper and lower edges of the panels to longitudinally close the interior space.

Abstract: A film bag having a bag body is formed with two front walls. A first lateral edge, which is formed by at least the two front walls, is connected at a first corner of the bag body to an upper bag edge. At the upper bag edge, the two front walls are interconnected by a fastening seam. Each of the front walls has, at the first corner, multiple lines of weakness that extend, in a curve and spaced from each other, from the first lateral edge up to the fastening seam. A tear-open aid is situated on the fastening seam. At least three lines of weakness are provided. The tear-open aid is designed and situated in such a way that the aid allows for a tearing-open, at the upper bag edge, between any two adjacent lines of weakness.
