Packaging container

A packaging container for a food product, the packaging container being configured to allow heating of the food product in the packaging container and comprising a tray for receiving a food product, the tray having a base and a peripheral wall, and a film lid for sealed attachment to an upper edge of the peripheral wall to seal a food product within the container, wherein the film lid comprises a laminated film material that includes a lower film layer made of a first plastics material for sealed attachment to the upper edge of the peripheral wall and an upper film layer made of a second plastics material that is attached by a peelable layer to the lower film layer so that it can be separated by peeling from the lower film layer, said upper film layer carrying at least one printed layer and said lower film layer being unprinted, wherein the first plastics material comprises a heat resistant plastics material, and the peelable layer is attached more strongly to the upper film layer than to the lower film layer so that it is removed entirely from the lower film layer when the upper film layer is separated by peeling from the lower film layer.
