<p><P>PROBLEM TO BE SOLVED: To provide an air seal which can maintain the cushioning-protecting action of an air chamber even when a part of the air chamber is broken. <P>SOLUTION: A central section film 2c is installed between a first external film 2a and a second external film 2b which are laminated with each other. The length of the central section film is shorter than that of the first external film and the second external film. A channel 9 for the air injection is formed by bonding the first external film and the second external film to their one-ends by a heat-sealing means. At the same time, a first air suction port 110 and a plurality of first air chambers 11 are formed by bonding the first external film to the central section film, and a second air suction port 120 and a plurality of second air chambers 12 are formed by bonding the central section film to the second external film. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
