Abstract (en)
A packaging material is intended for packaging food products which will be heated, e.g. from a frozen state, while still in the pack. The packaging material has two layers 10,12. The layer 10 is air and steam tight. The layer 12 is provided with apertures 14 which face the food product. The two layers 10,12 are laminated together with at least one channel extending from the apertures 14 along the interface between the two layers. When the food product is heated in a pack formed from the packaging material, vapour escaping from the food product passes out to the exterior through the apertures 14 and along the channels 18 between the layers 10,12 and is vented at an edge of the packaging material. <IMAGE>
