FIBC (Flexible Intermediate Bulk Container) bags, commonly known as fibc jumbo bags or super sacks, play a crucial role in bulk material handling. These industrial bulk bags are widely used in agriculture, construction, chemicals, food, and mining industries. But how are FIBC bags made? The fibc bags manufacturing process involves precision engineering, strict quality control, and advanced material technology to ensure durability and efficiency.
This guide breaks down the fibc manufacturing process into simple, easy-to-understand steps while covering fibc bag specifications, material composition, and advanced features like fibc liners and reinforced designs. If you’re looking for insights on what makes a high-quality bulk bag, this is the ultimate reference.
FIBC bags are primarily made from polypropylene fabric, a strong, lightweight, and durable material. The key components include:
The formula for an FIBC bag dimension depends on:
The process starts with melting polypropylene resin, which is mixed with UV stabilizers and other additives. The molten resin is stretched into thin fibc fabric tapes, which serve as the raw material for weaving.
These PP tapes are loaded onto circular or flat looms to weave fibc fabric, creating strong, flexible material for bulk bag construction. The density of weaving determines the bag’s strength and weight-bearing capacity.
If moisture resistance is required, fibc liners or laminated layers are added. This step ensures that the bag can store dry products like powders, grains, and chemicals without contamination.
Large rolls of woven fabric are precision-cut into panels that match specific fibc bag dimensions. This ensures consistency in size, shape, and load capacity.
Using advanced flexographic printing, company logos, handling instructions, and safety information are printed directly onto the fibc jumbo bags.
The lifting loops are made using strong polypropylene fibers, woven tightly to handle the weight capacity of the bag. These loops are attached at various points, depending on the bag type:
Workers stitch together the fabric panels, loops, and liners using industrial sewing machines. Each bag is assembled according to fibc bag specifications, ensuring it meets load-bearing and durability requirements.
Every fibc jumbo bag manufacturing company must adhere to strict quality control:
The completed bags are compressed and packed into bales for easy shipping. A standard bale may contain 50-500 bags, depending on size and type.
Once packaged, the FIBC bags are stored in warehouses or shipped to industries worldwide. Companies like XIFA Group supply bulk bags to sectors like food-grade packaging, construction, and industrial manufacturing.
FIBC bags come in various shapes and sizes, depending on their application:
The fibc bags manufacturing process involves multiple precise steps to ensure safety, durability, and efficiency. From extrusion to testing, each phase ensures the highest quality standards. Whether you need fibc jumbo bags for construction, food storage, or industrial applications, working with a reliable fibc jumbo bag manufacturing company like XIFA Group ensures top-tier performance and compliance.
