ABSTRACT:
A bag assembly includes a bag body and a valve unit. The bag body confines a receiving space and is formed with a vent hole. The valve unit is provided in the vent hole and includes an upper sheet and a lower sheet which are heat-sealed to the bag body and which cooperatively confine an air passage that is communicated with the receiving space. The upper and lower sheets of the valve unit have opposing inner surfaces which are electrostatically charged such that the upper and lower sheets normally adhere to each other via an electrostatic attraction at the inner surfaces thereof, thereby closing the air passage of the valve unit.
