Packaging using Gas Permeable Non-Woven Fabric based Film 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 high oxygen and carbon dioxide permeability of the Gas Permeable Non-Woven Fabric based Film establishes an ideal atmosphere for the specific perishable item, and therefore extends its shelf life. The establishment of lower oxygen and carbon dioxide atmospheres inside packages using Gas Permeable Non-Woven Fabric based film, also leads to reduction in the respiration rate of the perishable items.
