Abstract

The invention provides a self-sealing sleeve, which comprises a surface cover and a back cover connecting the front cover, wherein the right edge of the back cover is connected with a sealing lug which can be transversely opened, the lower edge of the back cover is connected with a sealing tongue capable of being vertically opened, a slot is formed on the sealing lug, and a bayonet to be inserted into the slot is formed on the sealing tongue; a card slot is formed on the sealing tongue; and the height of the sealing lug is half that of the right edge of the back cover. The sleeve forms a storage bag by the design of the sealing lug and the sealing tongue to be inserted into the sealing lug, pasting is avoided, manpower is saved, and working time is shortened. Adhesion is not required, so glue or double faced adhesive tapes are not needed; and thus, the environment is protected, and low carbon idea is realized. The height of the sealing lug is half that of the right edge of the back cover, and the printed products inside are insusceptible to falling if the sleeve is placed transversely, so that the files are loaded and protected effectively.
