FIBCs can be used to transport materials of various measurements and parameters. As a storage facilitator, FIBCs allow companies to consolidate valuable space in tight quarters. FIBCs can also be produced in a range of sizes, and therefore, fulfill the requirements of numerous businesses and applications. Whether a company needs to store and transport items that are bulky, heavy and large, or dense, loose and granular, the task can easily be accomplished with FIBC bags.
Since FIBCs first came into use, they have provided an efficient and affordable means for the safe and sanitary transportation of food and other products with high safety requirements such as petrochemicals and substances. For bags to meet FIBC safety requirements, they must pass performance tests to ensure there is no breakage, cut, tears or safety concerns. The making of a bulk bag begins with the feeding of polypropylene (PP) resin and other additives into an extruder to produce PP tapes that vary in thickness and width. The melted resin forms PP sheets that are stretched by rollers, then cut.
The tapes are then wound onto bobbins to start the weaving process which will create the FIBC fabric. The fabric weaving is performed on special looms to make either circular shaped bags or U-panels for the various other FIBC bag styles.
If the fabric is to be coated, the bags are vacuumed to release dust particles and passed through a static eliminator. A lamination process then applies a protective coating of polypropylene which will increase the bags resistance to moisture and sifting. Breathable fabric bags are left uncoated.
At this point, the bags are printed with an FDA approved printing ink, suitable for food contact. The ink that is used will dry quickly to eliminate smears or running.
Next, a computer program controls the precision cutting of the woven fabric from the rolls into the required sizes for the bag assembly process.
Finally, highly-trained employees complete the manufacturing process by sewing the fabric pieces together to create each bulk bag. All bags are sewn in an FDA approved clean room to maintain sanitation requirements. Filler cords are sewn into the seams and the bags will move on through different types of testing to pass UN regulations.
