Abstract
An air-tightness strengthening air enclosure comprises two outer films folded together vertically and two inner films disposed between the two outer films, the two inner films are adhered to each other by means of hot sealing and an air filling passageway is formed on one end of the two outer films, the inner film and the single outer film are adhered to each other by means of hot sealing to form buffer rooms at one side of the air filling passageway and next, the two outer films are adhered to each other by means of hot sealing to form air chambers at one end of the air filling passageway, and the air chambers are communicated with the air filling passageway. Whereby, the air filling speed can be faster, and the air in the buffer room presses the two inner films to shield the air filling passageway to prevent the air from being leaked out after the air in the air chamber flows into the buffer room.
