The tubular web of film has a plurality of plastic bags which can be separated from this web of film. This provides the advantage that the plastic bags can be made available to the user in a coiled form. This form is very easy to use, in contrast to a stack of loose plastic bags. In this case, each plastic bag is provided with first corner fold welding seams (8, 9, 10, 11). Each of these welding seams connects an outer web of film (1a, 1b) in each case to the fold part (5, 5a, 6, 6a) located immediately below it and to second corner fold welding seams (13, 14, 15, 16). The first corner fold welding seams (8, 9, 10, 11) are connected to a plastic bag closure welding seam (12). When the web of film is produced, the corner fold welding seams are firstly produced from a tubular film and the closure welding seam (12) is produced subsequently. <IMAGE> |
