A delivery bag (100) for pizza or other products includes upper, lower, rear, and first and second side panels (104, 106, 108, 110, 112) and a closure flap (114). The panels and flap (114) are made from a substantially flexible insulating panel material and have interior and exterior surfaces. The panel material is capable of conveying moisture from the interior surface to the exterior surface. The delivery bag also includes one or more pockets (142, 144) fixed to interior surfaces of the panels. A modular heating element (168) is disposed in each pocket. The delivery bag as described advantageously maintains temperatures of pizzas therein, yet allows relative humidity to decline over a specified period of time, thereby preventing e.g. pizza crust from becoming soggy. Corresponding methods provide similar advantages.
