ABSTRACT:
The present invention is directed to packaging methods for preserving a comestible, and for extending the shelf-life thereof, while simultaneously providing a freshly baked and locally packaged appearance. The package includes a retractable panel located at an inconspicuous place on the package which panel is pressed inwardly by atmospheric pressure, after the essentially inert modified atmosphere within the package has been partially absorbed by the comestible contained there within.
