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.

Method of heating contents in a self venting container

An improved bacon package is disclosed. The stiffening packaging element, commonly known as a bacon board, has full width top and bottom panels which support the bacon from the bottom and cover it over the entire top. Cover flaps on the ends of the top panel are defined by lines of weak bending resistance, and function to cover the ends of the array of bacon when the packaging element and bacon are enclosed in plastic films in a vacuum packaging operation.
