Abstract: The Breathable 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 Breathable 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 perishable items stored within the Breathable Container, and therefore extends their shelf life. The establishment of lower oxygen and carbon dioxide atmospheres within the Breathable Container using the Gas Permeable Film, also leads to a reduction in the respiration rate of the perishable items stored. The reduction in the respiration rate of the perishable items prevents loss of moisture, production of metabolic heat, yellowing, browning, and reduces the production levels of ethylene by the perishable items.
