<p>A container bag for filling bulk goods comprises a front (102), a back (101), side walls and a bottom (100), all of which define a chamber of the container bag. The upper surface of the bottom is provided with an extra sheet material (130) which is stitched on the bottom along the peripheral edges of the bottom and the longitudinal direction of the container bag. The longitudinal seams (110,110') formed are spaced apart from each other. An air guide channel is formed between two adjacent longitudinal seams (110, 110') and the bottom. At least one air guide channel is provided with an air injection pipe (140). The air injection pipe (140) makes air flow reversely and transversely through the channel between two points of each stitch and enter slowly into the adjacent air guide channels. When the air flows into the adjacent air guide channels, the air also flows longitudinally through the channel between the two points of each stitch and enters into the inside of the container bag, which brings into a fluidization effect.</p> |
