Zusammenfassung:	A one-way air outlet channel is disposed inside a vacuum compression bag. The one-way air outlet channel includes an air inlet opening, a horizontal air channel, inclined air channel and vertical air channel and an air outlet opening in communication with one another in sequence. One end of the horizontal air channel is the air inlet opening in communication with a space inside the bag body, and the other end of the horizontal air channel is in communication with the inclined air channel. A bottom end of the vertical air channel is in communication with the air outlet opening, and a top end is in communication with the inclined air channel, such that at least two corner points are formed, at a location where the horizontal air channel connects the inclined air channel and at a location where the inclined air channel connects the vertical air channel.
