Vacuum packing bag

Abstract

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.
