Abstract
A package for containing a product such as meat. The package includes top and bottom opposing flexible chamber sheets. These sheets are sealed together in a selected chamber seal zone to define a watertight chamber portion that is capable of containing the product. A hollow frame circumscribes the chamber portion. The frame supports the chamber portion when the frame is inflated. The need for a rigid tray may be eliminated by the inventive package.
