Abstract
A food sealing device for shrink-wrapping foods such as pizza includes a heat source surrounded by an inner shroud to create an updraft for heating the film. A second outer shroud is positioned around the inner shroud to prevent the film from contacting the hot inner shroud to prevent melting of the film against the inner shroud which might otherwise damage the film or the food item.
