Abstract: A package, which allows for butchering and packaging of fresh red meat at a centralized facility is provided which includes an impermeable tray supporting the product, a first film sealed to the tray for enclosing the product, a channel defined within the first film for exchanging gases into and out of the package, and a second impermeable film enclosing the first film, such that removal of the impermeable film provides for the exchange of gases into and out of the package. The channel for exchanging of gases may be perforations defined within the first film, a second highly permeable film sealed to the first film, or an enlarged opening formed within the first film, which is enclosed with a patch following adequate gas exchange at retail. Such gas exchange is required to release any low oxygen atmosphere and allow for the introduction of oxygen to the packaged meat product. The channel for exchanging gases having a gas transmission rate of at least about 50,000 cc/m2/24 hrs./atm. at 73° F.

Abstract: A package for a product, including: a support member having a peripheral flange and a cavity for receiving a product; a permeable film partially sealed to said flange to enclose the product; at least one channel between the permeable film and and flange; and an impermeable film enclosing the permeable film and at least one channel, the impermeable film being removable from the package such that removal thereof allows gas to flow into and out of the cavity through the at least one channel. The channel may comprise one or more grooves in the flange; a nonsealable substance present between the permeable film and the flange; or at least one corona-treated area of the flange, the permeable film, or both.

Abstract: A package which allows for butchering and packaging of fresh red meat at a centralized facility is provided which includes a support member such as a tray for receiving and supporting the meat, a permeable film enclosing the meat and an impermeable film enclosing the permeable film which remains in place during distribution and is removed at retail. A discontinuity in the seal between the permeable film and the tray provides for rapid introduction of oxygen to the packaged meat.
