Circular shaping ribs are installed in sections on the bag body. After being filled, the bag stands upright in a neat cuboid shape without bulging sides or sagging tilting. When stacked in multiple layers, the upper and lower bags fit closely and neatly, enabling ultra-high stacking in warehouses and greatly boosting storage space utilization.
The stiff fabric delivers long-lasting shaping performance and resists deformation after repeated filling. It is compatible with robotic arm grabbing and automatic palletizing & warehousing, with minimal dimensional deviation for standardized bag shapes.
