A bag or pouch container for use in cooking foodstuffs in a microwave oven, comprises two sheets of plastics material 8, 9 bonded or welded together along their edges 3 and closed or closable to permit cooking at above atmospheric pressure. The sheets are also bonded or welded together along a bonding line or lines 14 extending between edge regions to define compartments 5, 6 within the container for receiving and/or containing foodstuffs or other contents, with said line or lines being separable or rupturable at a desired temperature and/or pressure to permit flow of one foodstuff into the other compartment. A pressure relief valve or means 17 is operable to relieve pressure within the container during cooking whilst permitting cooking to continue thereafter at a pressure above atmospheric pressure. The sheets 8, 9 may be laminates comprising outer layers 12, 13 of polyester and inner layers 10 of peelable polypropylene and 11 of weldable polypropylene or polyethylene. Compartments 5, 6 may contain meat or fish, and sauce, respectively. |
