Throughout the industrial sector, corporations are always in search of ways to maximise profits while cutting costs and conserving space. Bulk bags have assisted thousands of businesses around the world to accomplish this purpose. From the food and pharma industries to factories that manufacture gardening products and construction tools, bulk bags deliver an efficient and reasonable way to package, stock, and carrier products.
Before a line of products is dispatched from the manufacturing plant, they are kept in containers that are safe, secure, and sterile. Whether the items consist of grainy bulk or enormous tools, the container must have the stability to hold the product weight and protect the contents from airborne pollutants and vapor.
When products are kept and transported in these high-quality quality bulk bags, the products of each bag reach their destination with the same clean and pure qualities as they were at the time they were packed.
The procedure of creating bulk bags also entails high levels of scrutiny when made at competent plants. The assessment helps assure each bag can fulfill global safety criteria for the transportation of various types of products such as chemicals, medicines, and consumable goods.

The Procedure of Bulk Bag Manufacturing Step by Step
Whether bags need to be made square, tall, overbuilt, or cost-effective, each sack must go through the cyclic testing procedure for SWL and security factor obedience. For products that require a low vapor transfer pace, bags can be dealt with laminate to enhance the moisture barrier.
The fabric must be interweaving and cut before bag construction starts. The procedure of manufacturing bulk bags can be broken down into the 11 steps which we have mentioned below.
Extrusion
The first step in the manufacturing of FIBC bulk bags involves extrusion, where a mix of high-quality ingredients is dissolved and provided shape into tapes of specific measurements. The materials which are utilized in this method include polypropylene (PP) granules, a little percentage of calcium carbonate, ultraviolet inhibitors, and perhaps color pigmentation. At this stage, the tensile durability of the tapes is persistent. The tapes are put into industrial bobbins in practice for the weaving step.
Weaving
Thereafter the tapes formed from the PP granules are put onto weaving looms. Here, the polypropylene material that constitutes the body of a bulk bag is woven into a contour. The resulting material is powerful sufficient to hold an extensive collection of industrial products and consumable items. However, it’s “breathable,” and therefore subject to the path of vapor. In the acquisition of delivering material for bulk bags, the woven PP material is also utilised for loading and unloading parts.

Moisture Proofing — Optional
It all depends on the particular requirements of a customer, the material can be handled with a particular laminate that makes each & every bag free from moisture. Moisture resistance can be achieved with the coating of lamination and it is considered very crucial for bulk bags while utilised in the transportation of granulated items, as well as for any other item that should always keep away from water and must never be disclosed to moisture.
Traditional, un-laminated polypropylene fabric consists of small strands with microscopic voids within each weave. In importance, the fabric is adaptable, and this can be of tremendous quality for storage and transportation purposes for different kinds of materials, but ill-suited for some select products. For example, sugar and salt should never be disclosed to water, including that type of water that gets stunk from the moisture in the air.
If we speak about the transportation of powdery products which are very light in weight such as flour laminated bags are considered very best. As that could otherwise filter through the woven voids of polypropylene material when shifted or trembled. During a multitude of flour shipments, the loss could be significant.
Cutting
The polypropylene fabric is grazed into a slicing device, where it’s slashed into shapes of specific measures. The measures are specified by whether the sides, rims, or undersides are being created during a given procedure. The technique by which the measurements are created is automatic, which assures exact sizes for each cut.
Printing
Once the portions of the polypropylene material have been sliced into a particular shape, then they are Put into a printing machine. Here, symbols are created on the fabric. If a company has a trademark name or symbol that they want to be published on a line of bags, printing happens at this stage. Relying on the trademark in question, a variety of colours may be executed. For the best possible beliefs, a heavy-duty printer is crucial for this technique.
Webbing
The grip pieces of bulk bags are created during this phase. Here, the tape that is s heavy on weight is Put into spun webbing material. Ribbons of this material are then cut to precise measurements, which are specified by the size of the bags in production. These ribbons form the handles or lifting loops of each bag.

Sewing Unit
At this stage, the different parts of bags which include both the square and rectangular pieces of polypropylene fabric, as well as the heavier lifting-loop strips are placed together with an industrial sewing device. Bulk bags are sewn jointly in gathering portions by a team of trained hands under the attentive sight of specialised supervisors. Each hem must be straight, tight, and secure, with no wrinkles or curves along any of the sides or tail ends.
Inspection
Once a line of bulk bags has been stitched together thereafter each bag is examined by quality control inspectors. The goal is to assure each bag fulfils the mandatory criteria of stability and durability for a product line related to bulk bags. If there are any bags which are insufficiently sewn, they are removed.
Burst Test
After all the above-mentioned techniques, an assigned number of bulk bags then are put into a testing ring to see if the bags fulfil the Safe Working Load (SWL) test. This stage helps to ensure that the bags which are in production are strong enough for their ultimate goal. In most cases, this step is conducted in advance of the general production of bulk bags. Once a derivative has been conducted, the burst test is once again carried out on random bags to assure the SWL is fulfilled.
Packing
Now till this stage, the huge manufacture of bulk bags has been completed and the bags are crystallised and grouped into preferred numbers for allocation in bulk amounts. The reduction is accomplished in a bale press, the outcomes of which entitle to the clean and easy packing of the bags.
Storage
With everything almost completed, the packed bulk bags are dispatched to a warehouse. Thereafter the bags which are stored in warehouses are waiting to be dispatched to various customer locations as per the requirements. Once a customer received those bags then the packed bulk bags are ready to be opened and put to use, whether the intentional objective is for the transportation or storage of building materials, debris, food products, or chemicals.
What Makes FIBC Bulk Bags Unique?
Throughout the industrial sector, Flexible Intermediate Bulk Containers (FIBC) are the best and ideal bags when it comes to storing and transporting bulky items.
How Are FIBC Bulk Bags Made?
The fabric for FIBC bulk bags is normally created with petroleum-based, virgin polypropylene. For added vapor opposition, some FIBCs also include inner linings created from low-density polyethylene (LDPE). The polyethylene assists in assure that no airborne vapor seeps through the fabric and saturates the contents within.
Singhal Industries Pvt. Ltd. is the best Fibc bulk bag manufacturer in the country. If you are planning to purchase any kind of bag, then you can also choose from these PP Jumbo Bags, PP Woven Bags, Woven PP Bags, HDPE Bags, PP Woven Bag.
