FIBC Bag Manufacturers – How is a big bag made?

FIBC bag manufacturers – The process of producing big bags


The FIBC manufacturing (Flexible Intermediate Bulk Container) process involves several key steps to ensure the production of high-quality, durable, and reliable bulk bags. As a leader amongst FIBC bag manufacturers, we have expertise in all the key steps of creating super sacks. Below are the most crucial stages of FIBC manufacturing:

Design and Specification: FIBC bulk bags manufacturers work closely with their clients to understand their specific requirements, including the intended use, capacity, dimensions, and desired features of the bulk bags. Based on these specifications, the design phase begins, incorporating factors such as load capacity, filling and discharging mechanisms, lifting options, and safety considerations.

Material Selection: The choice of materials is crucial in determining the strength, durability, and safety of FIBC bags. Big bag manufacturers commonly use materials that include woven polypropylene (PP) or polyethylene (PE) fabrics, which are known for their excellent tensile strength, tear resistance, and UV stability. The FIBC bag manufacturers select the appropriate material grade and thickness based on the large bulk bags intended application and environmental conditions.

Fabric Weaving: In this stage, the selected polypropylene or polyethylene fabric is woven into the desired dimensions. The weaving process involves interlacing the warp (lengthwise) and weft (crosswise) yarns on specialized looms, creating a strong and stable fabric structure. The weave pattern can vary per packaging bags manufacturers, such as a standard plain weave or a more complex circular weave, depending on the bag’s intended use and load requirements.

Cutting and Sewing: Once the fabric is woven, it is cut into panels of the required size and shape. The panels are then stitched together using high-strength sewing machines equipped with specialized stitching patterns. This stitching process ensures the panels are securely joined, providing structural integrity to the FIBC. Additional reinforcements may be added at stress points, such as the corners and lifting loops, to enhance strength and durability.

Lifting Loops and Filling/Discharging Mechanisms: The big bag manufacturers attach lifting loops to the bag during the sewing process. These loops, typically made of the same fabric as the bag or heavy duty bulk bags webbing, allow for easy lifting and transportation using forklifts or cranes. Depending on the FIBC bags design, filling and discharging mechanisms such as spouts, flaps, or valves may be incorporated to facilitate efficient loading and unloading of materials.

Printing and Labeling: An FIBC jumbo bag manufacturer often provides customization options for FIBCs, including the printing of logos, labels, safety instructions, handling instructions, or barcodes. This stage involves the application of ink or dye onto the bag’s surface using various printing techniques, ensuring clear and durable markings.

Quality Control and Testing: Throughout the manufacturing process, FIBC manufacturers implement stringent quality control measures. Random samples are regularly tested for strength, seam integrity, and safety factors to ensure compliance with industry standards and customer specifications. FIBC bulk bag manufacturers do testing may involve assessing factors like tensile strength, bursting strength, fabric weight, UV resistance, and electrostatic properties.

Packaging and Shipment: Once the FIBC bags pass the quality control checks, they are carefully inspected, folded, and packaged for shipment. Packaging methods may include stacking, baling, or palletizing, depending on the client’s requirements and mode of transportation. Proper labeling and documentation accompany the packaged FIBCs to ensure accurate identification and traceability directly form the FIBC bulk bag manufacturers.


By following these FIBC manufacturing processes and adhering to strict quality control measures, FIBC manufacturers can produce reliable and high-performance bulk bags that meet the diverse needs of industries such as agriculture, chemicals, construction, food, and pharmaceuticals.

Plastic Tax: What Does It Mean for FIBC Bag Manufacturers
Impact on FIBC Bag Manufacturers


With global plastic taxes finally in place, the burden of responsibility for virgin plastic waste is shifting from the consumer to the actual producers. Earlier this year, the state of California and the U.K. government introduced significant plastic reforms for packaging. This is a wake-up call for all fibc company owners in consumer-facing industries about how plastic taxes will affect Big Bag Manufacturers.

Major factors that will cause international organizations to take action on plastic taxes in the near future include the high societal and economic cost of dealing with plastic waste, increasing public awareness about sustainability, a better understanding of the relationship between plastic waste and climate change, bleak scientific predictions about the planet’s future, and recent extreme weather events.

The Tax Story

If you produce or import plastic packaging in the UK that doesn’t contain at least 30% recycled plastic, you’ll now have to pay a new tax. Plastic packaging is packaging that’s mostly made of plastic by weight.

This tax will not apply to any plastic packaging that contains at least 30% recycled plastic, or any packaging that is not predominantly made of plastic by weight. Imported plastic packaging will be subject to tax, whether the packaging is unfilled or filled. However, FIBC manufacturing can provide a solution to mitigate these taxes.

As FIBC Bulk Bags Manufacturers, we are focused on process excellence – this means consuming less energy and water, as well as using renewable energy sources. As aN FIBC jumbo bag manufacturer, we support plastic tax legislation, but we know that tax laws are notoriously complicated. There is a lack of global coordination on implementation, which impacts us, the big Bag Manufacturers. It might be tempting to wait for the end of the world, but the only way to future-proof FIBC Bulk Bag Manufacturers business is to act now. You need to embrace the new age of plastic tax legislation and act decisively.


FPS industrial packaging has emerged as a momentous change in bulk transportation and storage. Its versatility, strength, efficient handling, and environmental benefits make it an ideal choice for numerous industries. By leveraging FIBC bags, businesses can optimize their operations, improve product safety, and contribute to sustainable practices in packaging and logistics.
