• a non-collapsible tray inserted in said watertight internal housing, detached from said lower film and said upper film, trapped in said watertight internal housing, said non-collapsible tray being configured to house the food product and to support its weight, said non-collapsible tray having a bottom and raised edges in respect to the bottom and having a nominal height and defining together a containment volume of the food product inside the tray;
