What is the manufacturing process behind high quality PP woven bags?
The production of PP woven bags begins with the extrusion of polypropylene granules into thin tapes or filaments. These tapes are then stretched and wound onto bobbins to increase their strength through molecular alignment. The bobbins are loaded onto circular looms where the tapes are woven into a continuous fabric tube. This tube is then cut to the desired lengths and stitched at the bottom to form a bag. Depending on the final requirements, the fabric might undergo printing, lamination, or the addition of liners before the final inspection. Quality control at every step ensures the bags meet international safety standards.
