Abstract: The present disclosure relates to thermally insulating food packaging and more particularly to containers for storing or transporting food when the temperature of the food is significantly different to that of the surrounding environment. In particular, a food packaging material for enclosing food is described, the material including a first, moisture-permeable inner layer, a second, moisture-impermeable outer layer and a third, insulating moisture-tolerant layer disposed between the first and second layers and spacing the first and second layer apart, wherein the third layer has an undulating form including voids and wherein the first, second and third layers are arranged such that moisture emanating from food within the container passes through the first layer and the third layer and condenses on the second, moisture-impermeable outer layer.
