    摘要： A modified atmosphere packaging system and method creates a modified atmosphere in a package including an inner container and an outer container. The inner container is composed at least partially of a polymeric material substantially permeable to oxygen, while the outer container is composed of a polymeric material substantially impermeable to oxygen. After a food product such as raw meat is placed within the inner container, the inner container is flushed with a desired mixture of gases to substantially remove oxygen from the inner container. The flushed inner container is then sealed and inserted into the outer container without sealing the outer container. Next, the outer container is flushed with the desired mixture of gases to substantially remove oxygen from the outer container. After flushing the outer container, the outer container is sealed. An oxygen scavenger is provided in the package to substantially absorb any residual oxygen within the package.

    摘要： A packaging system and method utilizes a modified atmosphere package including a first package and a second package. The first package includes a non-barrier portion substantially permeable to oxygen, while the second package is substantially impermeable to oxygen. After a food product such as raw meat is placed within the first package, the first package is sealed and then inserted into the second package without sealing the second package so as to create a pocket between the first and second packages. The system and method first employ an oxygen reduction technique such as evacuation, gas flushing, and/or scavenging to quickly reduce the oxygen level in the pocket to a first non-zero level, and then employ an activated oxygen scavenger to further reduce the oxygen level to zero percent after the package is sealed. The oxygen scavenger is activated with an oxygen uptake accelerator to increase the rate at which the oxygen is absorbed. The oxygen scavenger is positioned external to the first package to aggressively absorb any residual oxygen within the pocket and the first package and absorb any oxygen that might seep into the modified atmosphere package.

    摘要： A container comprises a substrate and a multi-layer film The substrate has a bottom wall and a continuous base wall in which the continuous base wall encompasses the bottom wall and extends upwardly therefrom. The substrate comprises at least one particulate mineral filler and polypropylene. The multi-layer film is attached to the substrate. The multi-layer film comprises at least a first layer and a second layer The first layer comprises a metallocene-catalyzed polyolefin The second layer comprises polypropylene. The substrate and the multi-layer film are made in the absence of ethylene vinyl alcohol copolymer (EVOH), ethylene vinyl acetate copolymer (EVA), and ethylene methyl acrylate copolymer (EMA).
