Abstract: The Shelf Life Extending Container for fruits and vegetables extends the shelf life of various fresh fruits and vegetables and vase life of fresh cut flowers by changing the atmosphere in which these living products are stored and respires. The Shelf Life Extending Container does this by utilizing a Gas Permeable Non-Woven Fabric Based Film. The high oxygen and carbon dioxide permeability of the Gas Permeable Non-Woven Fabric Based Film establishes an ideal atmosphere for the multiple perishable items stored within the Shelf life Extending Container, and therefore extends their shelf life. The establishment of lower oxygen and carbon dioxide atmospheres within the Shelf Life Extending Container using the Gas Permeable Non-Woven Fabric Based Film, also leads to a reduction in the respiration rate of the perishable items stored.
