A package and a method for making a package which allows for the central processing of fresh red meat is disclosed which includes a tray, a first film enclosing the product within the tray and a second film, which is removed at retail, enclosing the first film. The first film and the second film are sealed to the inner periphery and the outer periphery, respectively, of the single flange of a conventional foamed or nonfoamed tray. The first film is a heat shrinkable film which is sealed to the inner periphery of the flange forming a first seal, trimmed outboard of the first seal, thereby forming an excess portion of the first film outboard of the first seal, and then subjected to a sufficiently high temperature to shrink the excess portion and thereby expose a sealing area on the outer periphery of the flange. The second film is then sealed to the sealing area on the outer periphery of the flange, forming a second seal such that the second film encloses the first film.
