Manufacturing Process

The manufacturing of Block Bottom Bags involves various vital steps. It begins with loading a tubular roll of coated/laminated - printed woven fabric on the machine. As it passes through the machine, the fabric is first cut according to the bag cut length. Then, at the end(s) of the bag, one side of the fabric is flipped over the other and sealed hermetically (air-tight) using heat and pressure. Another roll unwinds itself to provide a rectangular strip to overlap the bag's tight end(s). This process is called patching. The patch's material is the same as that of the bag, and the size is predetermined. The creation of the valve takes place while the patch is attached. Finally, the block bottom bag is collected at the end of the machine.
