A vacuum packing bag having a bag body (3), a reopenable seal and a vacuum valve (4) provided on the bag body. The bag body is formed by at least one front bag piece (1) and one back bag piece (2), and a fork-like opening (8) is formed at the top of the joint between the front bag piece and the back bag piece. A cover piece (5) is connected with the fork-like opening and has connection edges (52) and at least one movable edge (51). The connection edges are joined with corresponding edges of the front bag piece and the back bag piece at the fork-like opening, and the movable edge is joined with the upper edge of the front bag piece at the fork-like opening to form an opening (6) of the packing bag and constitute a movable seal. The vacuum packing bag has a simple design, an opening that can be sealed more quickly and conveniently for a labor-saving operation. |
