FIBC bags, also known as bulk bags, big bags, or jumbo bags, are large, flexible containers designed for the storage and transport of various materials in bulk. They are typically made from woven polypropylene fabric and are characterized by their ability to hold substantial weights, often exceeding 1,000 kilograms.
Features of FIBC Bags
Maximized Storage
Being lightweight, soft and pliable, FIBC bags are convenient to store. They easily fold up and become super compact. Since FIBC bags have barely any volume of their own, they’re easy to stack and store. The result is more floor and racking space for a more efficient workflow.
Labor Savings
Using FIBC bags is one way to maximize productivity and reduce labor costs. One bulk bag carries a significant amount of product compared to multiple smaller containers, bags or bins. By using bulk bags, there’s less time spent handling materials. It’s much more efficient to lift and haul one bulk bag compared to many other smaller storage bag alternatives.
Improved Transport and Handling
Using FIBC bags also means you won’t need additional pallets or loading units. When transporting full FIBC bags, they’re easy to stack safely, freeing up more space in trucks or on racks.
Versatility
FIBC bags are one of the most versatile solutions for containing, storing and transporting flowable goods. While FIBC bags come in standard sizes and designs, there are some solutions designed for particular applications and weights.
Types of FIBC Bags




U-Panel Bulk Bags
U-panel bags are constructed with three main body components: one piece that runs the full length of the bag forming the bottom and two sides (the “U”) and two additional pieces of fabric sewn between the “U” on two sides (the “panels”). Generally, U-panel bags will maintain a square shape when filled, especially with the addition of internal baffles. U-panel bags are an industry standard and the most popular type of construction.
Circular Bulk Bags
Circular bags, also called tubular bags, are constructed with two main body components: the body tube and the base. The body tube is made with seamless tubular fabric that forms all sides of the bag, allowing for stitching only at the top and base of the bag. Although the fabric is tubular, when filled, a circular bag will still somewhat resemble a square bag.
4-Panel Bulk Bags
A very common bulk bag style, 4-panel bags are constructed with five main body components: four side panels and the base. When filled, a 4-panel bag will hold its square shape similar to other construction types. Typically, 4-panel bags will hold their shape better than U-panel bags, while U-panel bags will hold their shape better than circular bags.
Type A FIBCs
These FIBCs are made from non-conductive fabric and do not provide any static protection. They are suitable for non-flammable materials that do not pose a risk of electrostatic discharge.
Type B FIBCs
Type B FIBCs are made from antistatic fabric designed to prevent the buildup of electrostatic charges. However, they do not provide full protection against sparks and incendiary discharges.Type C FIBC big bag from FPS.
Type C FIBCs
Also known as “grounded” FIBCs, Type C bags are made from electrically conductive fabric. They are equipped with grounding mechanisms to safely dissipate static charges, making them suitable for flammable materials.
Type D FIBCs
Type D FIBCs use static dissipative fabric to prevent the occurrence of incendiary sparks. They do not require grounding and offer protection against hazardous charges for both flammable and non-flammable materials.
Food-Grade FIBCs
These flexible intermediate bulk container bags are specially designed for transporting and storing food products. They adhere to strict hygiene and safety standards to prevent contamination and ensure the integrity of the food items.
Baffle FIBCs
These flexible intermediate bulk container bags have internal baffles or panels that maintain the shape of the big bags even when it’s partially filled. This design prevents the material from shifting excessively during transportation, optimizing stability and safety.
Polypropylene
This is the most widely used material for FIBC bags due to its strength, durability, and chemical resistance. It is lightweight yet strong, providing excellent tear and abrasion resistance. PP is also non-toxic, making it suitable for food-grade applications.
Polyethylene
PE is another thermoplastic material used in the production of FIBC bags, often chosen for its lower cost compared to polypropylene. It offers good chemical resistance and is suitable for non-abrasive materials.
Laminates
Laminates are made by bonding different materials together, such as combining a woven fabric with a plastic film. This provides enhanced barrier properties, such as improved resistance to moisture, vapor, and odors, as well as increased strength.

How to Choose FIBC Bags
This is one of the most important factors to look into when choosing FIBCs for your business. After all, you don’t want to end up with bags that are too small or too big for the volume of product you’re planning to fill them with. For that reason, you need to understand the size of your products in terms of the length and width they’ll occupy, then find a bag that can accommodate them. Keep in mind that although FIBC bags are flexible, they aren’t elastic, so being specific about the dimensions you require is a must.
Another thing to consider when selecting FIBC bags is their lining and coating materials. Whether they’re coated or uncoated, see to it your bags can protect the particular products you carry. Also, ensure that the linings are appropriate for the items you want to fill your FIBC bags with.
FIBC Bags come in a variety of construction styles. Therefore, before making your purchase, it’d be a good idea to choose one that best fits your business. In choosing the right construction style, some of the things to take into account are the products you’ll be filling the bags with, storage, transport, and discharge requirements. Common construction styles include duffle top bulk bags, open-top bulk bags, and spout top bulk bags.
Filling and emptying are other fundamental factors you should check as you’re choosing FIBCs. You need to think about how you’re going to fill the bags along with the size and shape of the tool you’ll use to accomplish that task.
The density and weight of the items you want to pack would help you decide on the size and volume of your FIBC Bags. This is because different products can weigh the same despite having different densities and volumes. For instance, 50 kg of cement will require a smaller container than 50 kg of cotton.
Process of FIBC Bags
Extrusion
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.
Weaving
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.
Vacuuming
If the fabric is to be coated, the bags are vacuumed to release dust particles, and the bag is then passed through a static eliminator.
Vacuuming
If the fabric is to be coated, the bags are vacuumed to release dust particles, and the bag is then passed through a static eliminator.
Lamination
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.
Printing
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.
Cutting
Next, a computer program controls the precision cutting of the woven fabric from the rolls into the required sizes for the bag assembly process.
Final Testing
While we continuously QA our bulk bags through the manufacturing process, at this stage, filler cords are sewn into the seams and the bags will move on through different types of testing to final approval.
How to Maintain FIBC Bags
Inspect Regularly
Before each use, inspect FIBC bags for any signs of damage, such as tears, holes, or weakened seams. Do not use damaged bags, as they may compromise the integrity of the contents.
Clean When Necessary
If FIBC bags become contaminated with foreign materials or residues, clean them thoroughly before reuse. Use appropriate cleaning methods and avoid harsh chemicals that could damage the fabric.
Store Properly
Store FIBC bags in a clean, dry, and well-ventilated area away from direct sunlight, moisture, and extreme temperatures. Proper storage helps prevent deterioration of the fabric and maintains the integrity of the bags.
Handle With Care
When filling, lifting, or transporting FIBC bags, handle them carefully to avoid punctures, tears, or abrasions. Use lifting equipment suitable for the bag's weight and size, and follow proper lifting procedures to prevent accidents.
Avoid Overloading
Do not exceed the maximum weight capacity or safe working load (SWL) of FIBC bags. Overloading can strain the fabric and seams, increasing the risk of failure during handling or transportation.
Use Inner Liners
Consider using inner liners or inserts to protect FIBC bags from sharp or abrasive materials. Liners can also help contain fine powders or granular materials and prevent leakage or contamination.
Replace Damaged Bags
If FIBC bags sustain significant damage or show signs of wear and tear, replace them promptly to maintain safety and prevent spills or accidents.
Dispose of Defective Bags Properly
If FIBC bags are damaged beyond repair or reach the end of their usable lifespan, dispose of them according to local regulations and environmental guidelines. Recycle or properly dispose of the bags to minimize environmental impact.
Carrying Fine Powder
FIBC bags, particularly those with sift-proof seams, work great when it comes to handling fine material such as cement, powdered metals, and minerals such as titanium dioxide, zinc ash, cobalt powder, carbon black, and food-grade powders such as skimmed milk and spices, to name a few. A breathable FIBC Bag may cause some loss of product, so choose a coated FIBC bag if you need to transport products such as grains.
Maintaining the Quality and Stability Of Agricultural Products
Inadequate storage and transportation of agro products contribute to waste and can be controlled with the help of proper packaging. Agricultural FIBC Bulk Bags are very popular in packing and transporting agricultural products such as grains, pulses, animal feeds, and fertilizers.
Safe Transportation Of Critical Products
Certain products are flammable and prone to static charges, which can build up to cause explosions. This makes it tricky to transport them and therefore, a packing solution that minimizes hazard is required. FIBC Bags with static control characteristics are perfect for the purpose of stacking, storing, lifting, and transporting petroleum and other flammable products. These bags are resistant to sparks and static which ensures safety during transportation.
Transportation Of Plastics
The thermoplastic industry serves nearly every other industry in the world and as such, depends heavily on bulk packing for the supply of its goods. Plastics are typically shipped from the manufacturing plant to factories in the form of pellets. FIBC Bags are an excellent option for safe and economic transportation of plastic pellets.
Construction and Building Materials
The construction industry relies on a fast and efficient supply of materials such as cement, sand, stone, gravel, as well as metals and minerals. Therefore, it’s extremely critical to have reliable and durable bags to transport construction materials. FIBC Bag fits the needs of the industry as they are sturdy and flexible enough to be moved around on-site. Plus, they can be easily used to transport materials across vast distances.
