Abstract
An airtight sheath having openable air intakes includes two outer films and two inner films heat-sealed together, an air inflation path, and multiple air columns. Upper edges of the two inner films extend to upper edges of the two outer films. A plurality of air guiding portions are disposed on an inner surface of at least one of the inner films and coated with a heat-resistant material. A plurality of air guiding holes are formed on each of the inner films between the plurality of air guiding portions and upper edges of the two inner films. When being inflated from the air inflation path, air currents flow among the outer and inner films through the air guiding holes to quickly fill the air columns and generate pressure in the air columns to automatically press the inner films against each other for prevent air from leaking out of the air columns.
