Foil combination of two connected bags

摘要

The bags (2,3) made of a foil are bounded by at least one weld seam (5), while parallel weld seams form the combination end welds. The boundary weld seams comprise a surface contour (10) of such size that the sum of the surface contours (11,12) is different at the end welds (8,9). Pref. the surface contour of boundary weld seam is less than the sum of surface contours of the end welds. The geometry of the surface contour of adjacent weld seam is unequal to the surface contour geometry of the end welds.
