Abstract: The invention provides a packaging which has a container part for receiving or containing food, the container part being covered with a sealing cover. The sealing cover comprises at least one vent which serves to release the overpressure generated during the process of microwave cooking. The sealing cover has a peeling strength which lies between 4 and 20 N/15 mm, preferably between 7 and 15 N/15 mm, in particular 8 N/15 mm. According to one embodiment, the sealing cover consists of a PET-PP-composite, with the PP-layer used as the sealing layer, which is sealed to the container. In one embodiment, instead of PET, an oriented polyamide (OPA) is used. In one embodiment, the side of the sealing layer, which faces the lower part of the packaging is covered with an anti-fogging-coating, in order to prevent the condensing of water on the sealing.
