A microwave carton (2) including a bottom tray-shaped portion (4) having upstanding inner side wall panels (10,12,14,16) and a telescoping top portion (6) having downwardly extending side wall panels (30,32,34,36) wherein a layer (28) of microwave reflective material covers the entire interior surfa

A microwave carton (2) including a bottom tray-shaped portion (4) having upstanding inner side wall panels (10,12,14,16) and a telescoping top portion (6) having downwardly extending side wall panels (30,32,34,36) wherein a layer (28) of microwave reflective material covers the entire interior surface of the top portion (6) and a vapor escape means (24) is provided for allowing vapor generated within the carton (2) to be vented to the exterior of the carton (2) by passing through a space formed between one inner side wall (10,12,13,16) and one outer side wall (30,32,34,36). The vapor escape means (24) may be formed by removing an upper portion of one of the inner side walls (10,12,14,16). One of each pair of corresponding sidewalls may be angled to for a space therebetween through which vapor may escape.
