Abstract
A package for preserving produce in a wholesome condition for an extended period of time is formed by a sealed container enveloping the produce and filled with a preservative gas which inhibits bacterial growth. The container is formed by a high barrier film which is so perforated as to provide a gas pressure within the container sufficient to inhibit air inflow into the container and to assure gas outflow from the container to prevent its distortion.
