Habe gestern eine Pizza von Rewe erhalten und fand beim Öffnen das Kreisziel auf der Plastikabdeckung des Teigs wie im angebrachten Bild. Nur neugierig zu wissen, was es ist und die Verwendung davon!

it’s an airlock. let’s out CO2 the yeast in the dough produces but doesn’t let on air from outside. so the dough stays fresh without blowing up the plastic wrap (:
I guess it was fresh pizza dough? The yeast produces CO2 and this is an outlet for it, so that the package won´t explode.
Dough with yeast, yeast eats sugar in the dough, poops out CO2, CO2 expands plastic packaging, plastic packaging bursts.
To prevent the last two points from happening, there is a valve in the packaging that allows the CO2 to escape through the film.
Ah! Now I understand. Thank you all for the swift reply 👍
