Make sure that the part of the film you want to seal is dry and that no liquid is sucked in during the vacuuming process. Make absolutely sure that there is no kink in the sealing bar. If you find a kink, you can simply pull off the sealing bar and straighten it again. The holes in the ventilation flap must also be clean. It is also advisable to use the moist sealing function, as this extends the sealing time and the film can be sealed better.
