  • Publication number: 20100189848
    Abstract: A packaging system for perishable food products, especially for meat products discharging residual blood and other natural fluids, comprising a tray and an outer tray closure film spanning the perimeter of the tray, wherein the tray possesses structural features for transmission of draining fluids away from the meat product extending the shelf-life of the packaged meat while avoiding the usual “browning” appearance. Instead, the natural redness and appetizing appearance or “bloom” properties of the meat product are maintained for enhanced customer acceptance. The outer film preferably incorporates at least a sufficient amount of a biostatic and/or biocidal agent. The tray includes an elevated meat supporting porous film, and a reservoir below the porous film for collecting descending fluids. The descending fluids are managed by a series of elevations and lower channels for collection/retaining the fluids in supporting relationship with the porous film.

  • Patent number: 7722937
    Abstract: In accordance with one aspect of the invention, a material, such as a plastic film, is used to separate independent food elements. The independent food elements and the separation material are packaged together using a unifying outer package. At a point in time when the customer decides to eat the food, the outer package is opened and the film that separates the different food elements is removed, either manually or automatically. This marks the first point in time that the separate elements come into contact with each other. Therefore, the food product is maintained at the highest level of integrity until the time of usage by the customer. Methods and a machine for layering the contents of the packages so as to form a completed assembly for the packaged elements is also described.

  • Publication number: 20090297667
    Abstract: A product packaging comprises a base, a lid, a meat product, and a gas within a space between the base, the lid, and the meat product. The base and the lid form a cavity having a first volume. The meat product has a first color and a second volume. The second volume is smaller than the first volume. The cavity is configured and arranged to receive the meat product. The space has a third volume that is the difference between the first volume and the second volume. The gas within the space comprises no greater than 30% carbon monoxide, and at least one of the base and the lid has an oxygen transmission rate of 0.1 to 15 cc of oxygen per package in 24 hours so that in 18 to 90 days the first color of the meat product has noticeably changed to a second color.
