The disclosure refers to a packaging device for manufacturing a packaging for a foodstuff. In particular, the packaging may include a trough-shaped lower packaging part and a top film which can be sealed together along their edges by means of a sealing tool of the packaging device. In order to improve a packaging device completely without evacuation or by evacuation in a simple and inexpensive manner with only a slight negative pressure in such a way that sufficient vapor purging is possible and at the same time cooling of the foodstuff before sealing or excessive degassing of the foodstuff does not take place, vapor can be introduced under pressure between the lower packaging part and the top film at at least one vapor entry point before sealing and can be released into the surrounding atmosphere at an outlet point from the packaging.
A packaging device for manufacturing a packaging for a foodstuff, the packaging comprising a trough-shaped lower packaging part and a top film, which can be sealed to one another along their respective edges by means of a sealing tool of the packaging device, the sealing tool comprising a vapor supply line and a discharge line, wherein vapor can be introduced under pressure between the lower packaging part and the top film at least at a vapor inlet point in communication with the vapor supply line before sealing and can be released from the packaging into surrounding atmosphere at an outlet point in communication with the discharge line, and wherein the sealing tool comprises a suction line for providing a negative pressure between the sealing tool and the top film to increase space for vapor flow between the top film and a surface of the foodstuff in the lower packaging part, and wherein the sealing tool comprises an extraction line which connects a space between the sealing tool and the lower packaging part to the surrounding atmosphere.
A packaging device for manufacturing a packaging for a foodstuff, wherein the packaging includes a trough-shaped lower packaging part and a top film, the packaging device comprising:
A packaging device for manufacturing a packaging for a foodstuff, the packaging comprising a trough-shaped lower packaging part and a top film, which can be sealed to one another along their respective edges by means of a sealing tool of the packaging device, the sealing tool comprising a vapor supply line and a discharge line separate from the vapor line, wherein vapor can be introduced under pressure between the lower packaging part and the top film at least at a vapor inlet point in communication with the vapor supply line before sealing and can be released from the packaging into surrounding atmosphere at an outlet point in communication with the discharge line, and wherein the sealing tool comprises a suction line for providing a negative pressure between the sealing tool and the top film to increase space for vapor flow between the top film and a surface of the foodstuff in the lower packaging part.
