| abstract |
This invention relates to extending shelf life of food product such as wine packaged in flexible bags. Oxygen transport into the wine through the flexible-bag walls reduces the shelf life of the product. Similarly, oxygen in air trapped in headspace of a flexible bag packaged with the food product such as wine eventually dissolves into the wine, and consequently diminishing its shelf life. This invention relates flexible bags that provide inert gas cavities around the wine and in the headspace above the wine, and the process of making such flexible bags, such that the total oxygen content inside an unfilled (with product) flexible bag is less than 10%. |
