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

    摘要： According to one embodiment, a container comprises a base. The base has a bottom wall and a continuous base wall which encompasses the bottom wall and extends upwardly therefrom. The base is made from a mixture of a polyolefin and a filler. The mixture is from about 30 to about 75 wt. % filler and from about 25 to about 70 wt. % polyolefin. A high aspect ratio filler and a low aspect ratio filler are included in the filler, with the high aspect ratio filler having an aspect ratio of at least 5:1 and the low aspect ratio filler having an aspect ratio of less than about 3:1. The filler comprises at least 50 wt. % of low aspect ratio filler.

    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.
