An airtight zipper construction is provided that can be installed on any bag body and seals the bag completely. The airtight zipper construction comprises a first zipper tape having a first zipper groove, a second zipper tape having a sealing portion at its end and a second zipper groove engaged with the first zipper groove, and a first slide with a separating portion. The separating portion divides the inner chamber of the slide into an upper guiding passage and a lower guiding passage. The first zipper tape and the second zipper tape are inserted through the upper guiding passage and the lower guiding passage, respectively. The first zipper tape is engaged into the second zipper tape from zipper head toward zipper end, with the first zipper tape covering the second zipper tape, and the first slide jammed into the sealing portion without any gaps.
