シート。[Claims for Utility Model Registration] 1. A flat cylindrical band formed by heat-sealing both longitudinal edges of two overlapping belt-shaped heat-fusible films, each with a width wider than the cylindrical band. A non-fusible coating is applied to the inner surface of one of two thin heat-fusible film strips, and slits that serve as self-sealing valves are carved at predetermined intervals on the surface of one of the strips. In addition, a blowing tube formed by heat-sealing both longitudinal edges of both strip films is inserted through the tube, and at least one end of the tube protrudes from an end of the cylindrical body. heat-seal transversely to the cylindrical body at both ends of the cylindrical body and at a position outside the slit of the inserted blow tube to form a plurality of individually partitioned and continuous inflatable air bags. An inflatable self-sealing cushioning sheet. 2. The expandable self-sealing cushioning material sheet according to claim 1, wherein the non-fusible coating film is formed from a colored or non-colored silicone-based heat-resistant release agent. 3. The inflatable self-sealing cushioning material sheet according to claim 1, wherein the slit is formed into a short minus shape, a plus shape, or an x shape, cut into one of the film strips in the transverse direction or the length direction. 4. The expandable self-sealing cushioning material sheet according to claim 2 or 3, wherein a slit is formed in one of the strip films, and a non-fusible coating film is applied to the inner surface of the other strip film. 5. The inflatable self-sealing cushioning material sheet according to claim 1, wherein the transverse heat seals partitioning each of the air bags are formed by two seal lines. 6. The inflatable self-sealing cushioning material sheet according to claim 5, wherein the non-fusible coating film is partially applied only to a region corresponding to a region where the two seal lines are to be formed.
