ABSTRACT:
A ventable container comprises a body with a lip hermetically sealed by a film. A hole is provided in the lip of the container and a layer of hot melt adhesive disposed around the hole adhesively seals the film across the hole. When the container and the product are heat processed, the film flexes away from the tray, and the hot melt adhesive layer softens and releases the film for venting of the container. Upon cooling, the film once again bonds to the hot melt adhesive and seals the container.
