9. My company uses both gas flushing and vacuum packaging. Why do we need to use OxyFree®?
By using OxyFree® sachets, you can extend the shelf life of your food products much longer than gas flushing or vacuum packaging. When an OxyFree® sachet is used with proper packaging and sealing, it can bring the oxygen level down to reliably 0.1% or less in a matter of one or two days. With a high barrier packaging film it can maintain an oxygen free level (<0.01%) throughout the product’s shelf life. Such results are impossible to achieve with either gas flushing or vacuum packaging. First, there is always some residual oxygen (0.3-5% depends on methods and equipment) left in the food package. Second, during the storage of food, oxygen from the air can enter the food package increasing the oxygen level. Over time, the oxygen level continually rises inside of the package. Also, the increased oxygen level limits the shelf life that such methods can achieve.
