Claims14
Method for operating a thermoforming packaging machine, said method comprising the steps of:
- forming a trough into a first film web in a forming station;
- creating a flange surface that at least partially surrounds the trough;
- creating a cutting line into the first film web within the flange surface in a cutting station that is disposed in a processing direction downstream of the forming station;
- creating an internal sealed seam between the flange surface and a second film web in a first sealing station that is disposed downstream of the cutting station in order to place the second film web onto the flange surface, wherein the internal sealed seam is created between the trough and the cutting line;
- and
- creating an external sealed seam between the second film web and the flange surface, wherein the external sealed seam is created outside of the cutting line.
