FIBC bulk bags or flexible intermediate bulk containers, are a popular choice for storing and transporting dry bulk materials. They are known for their durability, affordability, and ease of use.
But how exactly are these versatile bags manufactured? This article will delve into the fascinating process of FIBC bulk bag production.
The journey begins with plastic pellets—typically polypropylene resin—being fed into an extruder machine. This machine melts the resin and forces it through a die, shaping it into flat tapes of varying widths and thicknesses. Additives may be included during this stage to enhance specific properties like UV resistance.
Then comes the weaving. The polypropylene tapes are then wound onto bobbins and fed into weaving looms. These looms interlace the tapes in a specific pattern, creating a strong and flexible fabric that forms the body of the FIBC bulk bag. [1]
Several optional steps can be incorporated into FIBC bag production depending on the specific application.
First, a thin layer of plastic film can be laminated to the fabric, enhancing moisture resistance and preventing product sifting. For additional protection against UV rays or chemicals, a special coating can be applied to the fabric.
FIBC bulk bags can be custom-printed with logos, handling instructions, or other relevant information. [2]
Once the fabric is produced and any additional treatments are complete, it’s precisely cut into the desired shapes for the bag’s body, top, bottom, and lifting loops (handles).
Skilled technicians stitch these pre-cut pieces together using heavy-duty sewing machines, creating the final form of the FIBC bulk bag.
Rigorous quality control checks are performed to ensure the bag meets all safety and performance standards. This may involve testing the lifting loops, seams, and overall strength of the bag.
