the microwave energy interactive material of the top panel is supported on a first polymer film,
a moisture-containing layer is joined to the microwave energy interactive material of the top panel, and
a second polymer film is joined to the moisture-containing layer in a patterned configuration to define a plurality of expandable cells between the moisture-containing layer and the second polymer film, wherein the expandable cells are operative for inflating in response to microwave energy.
17. The tray assembly of claim 16 , wherein the first polymer film faces the interior space of the carton, so that the inflating of the expandable cells urges the microwave energy interactive material towards the interior space.
18. The tray assembly of claim 1 , wherein the cuts comprise slits, cutouts, or any combination thereof.
19. A tray assembly for preparing a food item in a microwave oven, the food item having a surface intended to be browned and/or crisped, the tray assembly comprising:
a first tray for underlying the food item; and
a second tray for overlying the food item, the second tray being pivotably connected to the first tray for pivoting the second tray relative to the first tray between an open position and a closed position,
wherein the first tray and the second tray each include at least one flanged receiving element for receiving the food item, the flanged receiving element comprising a plurality of hingeable flange segments including microwave energy interactive material, the hingeable flange segments being operative for bringing the microwave energy interactive material into proximity with the surface of the food item.
