ABSTRACT:
A sealed package, and a method of heating a sealed package of material are disclosed wherein the material is capable of generating vapor from a substance contained therein when the temperature of the material is raised. At least a portion of the packaging structure comprises a plastic film. Thermal energy is applied to the material causing the plastic film to be displaced by generated vapor. After the film is displaced, a vent hole appears in the film, venting the vapor without substantial rupture of the film.
