GROOVED LID FOR PACKAGING OF FRESH FRUITS, VEGETABLES AND FLOWERS IN CORRESPONDING MODIFIED ATMOSPHERE TRAYS

摘要

This invention relates to novel designs of tray lids and tray bases for modified atmosphere packaging of fresh fruit, vegetables and cut flowers. More particularly, this invention relates to novel designs of landscaped lids and corresponding tray bases which enable cooling air to be circulated in single or multiple directions through stacked lid and tray combinations that contain fresh fruits, vegetables and cut flowers in a modified atmosphere environment. The gas-permeable modified atmosphere package comprises a lid constructed of a polymer, the lid having on the top surface thereof at the mid-regions of each side a plurality of raised load supports and in between grooves; and a base with a hollow interior constructed of corrugated kraft paper polymer and having a configuration at the top edges which conforms with the interior profile of the lid; the grooves enabling air to be circulated over the lid when one package combination is stacked on another.
