Abstract (en)
The invention shows a packaging container (100) for a microwave oven, which enables an operator to easily recognize if the container content has been heated and if the container has been automatically opened. The container has been hermetically sealed by heat-sealing with a plastic film, wherein the container comprises a vapour release seal part (3) with a weakened part (4). The vapour release seal part is provided with a mark developing means, with which an opening of the vapour release seal part can be recognized by an outer colour difference between the opened vapour release seal part (3) and adjacent parts. This colour difference is caused by an opacification or whitening due to cohesion failure, when the vapour release seal part is peeled off the container.
