MODIFIED ATMOSPHERE PACKAGE

摘要

A modified atmosphere packaging system and method creates a modified atmosphere in a package (10) including an inner container (14) and an outer container (12). The inner container (14) is composed at least partially of a polymeric material substantially permeable to oxygen forming a tray (16), while the outer container (12) is composed of a polymeric material substantially impermeable to oxygen. After a food product such as raw meat (26) is placed within the inner container (14), the inner container (14) is flushed with a desired mixture of gases to substantially remove oxygen from the inner container (14). The flushed inner container (14) is then sealed and inserted into the outer container (12) without sealing the outer container (12). Next, the outer container (12) is flushed to remove oxygen. After flushing the outer container (12), the outer container (12) is sealed. An oxygen scavenger (28) is provided in the package (10) to substantially absorb any residual oxygen within the package (10).
