Abstract: A non-latex balloon has at least two outer balloon layers of a polymer such as nylon, with an inner layer of heat-sealable material. A self-sealing valve is heat-sealed to the inner surface of one of the outer layers. An inner balloon layer is placed adjacent the outer balloon layers and heat-sealed to one of them to form an enclosed pocket. Two inner balloon layers may be used to form two pockets. The seal of the pockets may be releasable by the user to put a sundry item into the pocket or the sundry item may be manufactured into the pocket. A method of manufacture of a balloon product includes the steps of: placing a valve between two outer sheets of heat-sealable material; placing an inner sheet of material between the two outer sheets; and heat-sealing the valve to the outer sheets and heat-sealing the inner sheet to an outer sheet to form a sealed balloon with a pocket between the inner sheet and the outer sheet. Two pockets may be produced by using a second inner sheet.
