Abstract: This invention is related to a self-sealing valve for inflatable articles, including balloons, made of non-elastomeric material of the kind of valves formed by multiple layers of thermo-plastic film joined by heat which form three sections; a nozzle, main channel and a multi-valved section. This valve design permits the production of balloons or inflatable objects with a valve without requiring sophisticated machinery for the exact placement of the valve in the article or balloon. This is characterized in that the nozzle of the article consists of four films; two external films with an outer face that is compatible with heat fusion with the material of the inflated article in which the valve is to be placed and inner faces that are compatible with each other and the inner films with outer faces that are compatible with the outer films and inner faces that are incompatible with each other and outer films.
