An air enclosure with a reinforced air sealing function is provided to make a buffer chamber function as an air storing space when the air of an air chamber leaks out and to improve the air charging speed by directly charging the buffer chamber. An air enclosure with a reinforced air sealing function is composed of: two outer films(2a,2b) vertically stacked; two inner films(1a,1b) disposed between two outer films; one air charged passage(9) formed by bonding two inner films by a thermal sealing unit, in order to move the air; plural air chambers(11) positioned at the side of the air charged passage and formed by bonding two outer films by the thermal sealing unit, in order to store the air; at least one spacer line(4a) disposed between the air charged passage and the air chamber; at least one air injection port(2e) formed at the spacer line by separately applying heat resisting materials(1c) between two inner films in order and bonding two inner films by the thermal sealing unit, in order to make the air charged passage and the air chamber communicate with each other; and at least one buffer chamber(8) disposed at the lateral sides of the air charged passage and formed between one outer film and the inner film adjacent to each other to store the air. The air enclosure prevents the air from leaking by pressing two inner films by the air of the buffer chamber and sealing the air charged passage after the internal air of the air chamber flows into the buffer chamber.
