Abstract: An air cushion foil (1) especially for packaging purposes, comprises a first smooth foil (2) of synthetic material and a second foil (4) having pocket-like depressions (3). The two foils are so connected with one another that the first foil (2) closes the pocket-like depressions (3) of the second foil (4) and forms pockets having pocket bases (6), pocket side walls (7) and curved transition regions (8) between the bases and the side walls. The pocket bases and curved transition regions are subjected to a roughening pre-treatment and are covered with a layer (9) of adhesive so that the foil can be stuck to goods to be packaged and pulled away without leaving adhesive on the goods.
