An inflatable valve for an inflatable packaging cushion has first and second juxtaposed plys of thermoplastic material secured together by first and second spaced-apart heat sealed side seams to form a flattened tube having an interior sealing end positioned in an inflatable packaging cushion and an inflation probe insertion end positioned exteriorly of the inflatable packaging cushion. An adhesive strip is applied to the second ply and extends between the heat sealed side seams. Release paper covers the adhesive strip; wherein the release paper is removed and the first and second plys are pressed together, the adhesive strip seals the first and second plys together. Spot seals at the intersections of the heat sealed side seals and the adhesive strip sealingly join the side seals and the adhesive strip. The adhesive strip is provided by one side of a two-sided adhesive tape or as a layer of adhesive. The first ply only partially overlies the adhesive strip, wherein when the release paper is removed, a portion of the adhesive strip is exposed and may be used to secure the inflation end of the inflation valve to the inflatable packaging cushion.
