Method and manufacturing device for sterilising an interior of a packaging, and packaging with sterilised interior

A manufacturing device for sterilizing a sealed interior of a packaging, wherein

• the manufacturing device comprising an application unit, a receiving unit, a positioning unit, a sealing unit, and an activation unit, wherein
• the receiving unit is adapted to receive an upper film with a first surface and a lower part, wherein
• the positioning unit is adapted to place the upper film on the lower part in such a way that the upper film and the lower part delimit the interior of the packaging at least in regions and that the first surface of the upper film faces the interior of the packaging at least in regions and a sterilizing substance is arranged inside the packaging, wherein
• the sealing unit is adapted to seal the upper film on the lower part, wherein
• the activation unit comprises an evaporation unit, wherein
• the activation unit is adapted to activate a sterilizing substance applied on the first surface from an outside by delivering a water vapor treatment to the sealed packaging from a steam nozzle outside of the packaging with a predetermined activation temperature and/or a predetermined activation pressure for a predetermined activation time period, and wherein
• the application unit is adapted to apply the sterilizing substance to the first surface as a layer to the first surface of the upper film.
