1. A Preservation System including an air-tight food storage container comprising a film which comprises a fabric substrate and a coating on the fabric substrate having an oxygen permeability of at least 100 cc/100 in2/day/atm and having a carbon dioxide permeability of at least 600 cc/100 in2/day/atm and at most 3,888,889 cc/100 in2/day/atm; further comprising a carbon dioxide solenoid, sensor, data logic controller, touch screen interface, membrane exposure panel, digital scale, wherein the data logic controller and the touch screen user interface, based upon the food items being stored and their respective weights measured by the integrated digital scale, automatically activates the carbon dioxide solenoid to allow a specific amount of CO2 to enter the container while additionally activating a vacuum pump for a specific amount of time and activating a membrane exposure panel motor to adjust the exposed surface area of the film in order to modulate the atmosphere within the container to the optimal levels for the multiple food items being stored, and further comprising a sensor array that provides real time monitoring of the atmosphere within the food storage container to provide continued automatic operation; whereby the gas mixture within the container is pulled into the sensor array via a sensor array pump and a sensor array gas tube and recirculated back into the container.
