6. Winding on Winders
In this process the stretched threads are winded on the winders so that they can be shifted on the looms

7. Weaving on circular looms
In this process the threads are woven to make a circular cloth of plastic threads. The woven cloth is collected in rolls.
8. Cutting and stitching
In this process the rolls of cloth are cut into the size of bag. The bottom of bags are then stitched.
9. Printing the Logo design of buyer
In this process the previous cut and stitched bags are printed as per customer requirement.
10. Bail Pressing
In this process the printed bags are pressed in the form of bails. This is the last process of PP bags manufacturing.
11. Dispatch
In this process the pressed bails are loaded into a vehicle and sent to their destination for further use
