Abstract
An improved container for transporting food and similar products is provided. The container employs one or more layers of a breathable material which is permeable to water vapor but repellent to liquid. By enclosing hot food in this container, moisture vapor from the food dissipates away from the food and avoids the soggy texture which often accompanies transported food. The container of the present invention has a wide range of possible applications, including everything from delivery of individual pizzas to large scale relocation of food for institutional purposes.
