Abstract

A food packaging which can be microwaved, comprises a lower section for holding the food (100), a sealed lid film (110), and at least one valve (120) incorporated in the lid film. The valve relieves pressure that builds up during heating. The film has a peel force of 4-20 N/15mm, preferably 7-14 N/15mm, especially 8 N/15mm, and consists of a PET - PP laminate, where the PP layer acts as the sealing layer (140) and the PET layer is the upper layer (130).
