ABSTRACT:
Inflatable packaging including a valve formed by a channel made between two flexible sheets extending at least partly inside the inflatable packaging and having a first opening communicating to outside of the packaging and a second opening communicating to inside of the packaging, the two flexible sheets being designed to be pressed against each other as soon as a force keeping the flexible sheets apart is removed, thus preventing an inflating gas from escaping from the packaging, wherein the two flexible sheets extend between two edges of the packaging and the first opening coincides with a second opening passing through one wall of the packaging, the edges of the first opening and the second opening being welded to each other and, upstream of the first opening, the two flexible sheets are welded to a body of a tab cut into the one wall of the packaging, wherein the tab includes one tab end by which the tab may be grasped which is free with respect to the two flexible sheets, and the tab is isolated from an internal volume of the packaging by a peripheral weld.
