FIBC Production Process
From Quality Raw Materials to Finished Bulk Packaging Solutions
As a dedicated supplier of Flexible Intermediate Bulk Containers (FIBC), Jumbo Bags, Bulk Bags, and PP Woven Packaging Solutions from India, FIBC SILVASSA supplies bulk packaging tailored to your exact technical and operational requirements. Explore the complete eight-stage FIBC production process flow—from polypropylene tape extrusion and fabric weaving to bag assembly, quality inspection, and dispatch—to understand how each specification shapes the finished bags we supply.
8-Stage FIBC Production Process Flow
Understanding the jumbo bag production process helps procurement and engineering teams select the right fabric construction, coating, loop design, and closure options for safe bulk material handling.
Raw Material Selection
The FIBC production process flow begins with selecting virgin polypropylene (PP) granules suited for high-tenacity woven packaging. Depending on the required fabric properties and bag specifications, application-specific additives such as UV stabilizers, calcium carbonate, or masterbatch pigments are blended to support strength, durability, and outdoor exposure requirements.
PP Tape Extrusion
Polypropylene granules and selected additives are melted and extruded into a continuous polymer film, rapidly cooled, and slit into precision-width flat tapes. These tapes are heated and stretched under controlled tension to orient the polymer molecules, developing the tensile strength needed for woven FIBC fabric.
Fabric Weaving
High-tenacity PP tapes wound onto bobbins are loaded onto circular or flat weaving looms. The tapes are interlaced in warp and weft directions to create strong polypropylene woven fabric in specified widths and fabric weights (GSM), suitable for different FIBC designs and load requirements.
Lamination and Printing
Where moisture protection or fine-powder containment is specified, woven fabric undergoes optional coating or lamination with a polymer layer. Customer-specific printing is also applied to fabric panels to display company branding, product identification, handling symbols, and safety information.
Fabric Cutting
Woven fabric rolls are fed through cutting equipment where the material is sized into body panels, base and top sections, spout components, and internal baffles. Heavy-duty webbing is also cut into lifting-loop lengths according to the dimensions on approved bag drawings.
Stitching and Bag Assembly
Cut fabric panels are stitched using heavy-duty industrial sewing machines to form U-panel, circular, and Q-Bag (also called Baffle Bag) designs. Lifting loops, filling and discharge spouts, inner liners, sift-proof cords, document pouches, and bag labels are attached to match the buyer’s functional configuration.
Quality Inspection and Testing
Assembled bags undergo inspection of dimensions, stitching quality, fabric condition, printing clarity, lifting loops, and accessories. Applicable performance tests are carried out according to the agreed bag specification, Safe Working Load (SWL), and relevant industry standards.
Packing and Dispatch
Finished FIBC bags are folded, compressed into uniform bales or stacked on pallets, wrapped in protective outer packaging, and supplied with the required bag labels and shipping labels. The packed consignments are then prepared for timely domestic delivery or international export dispatch.

FIBC Bag Types by Construction & Application
We supply a full range of FIBC bag constructions. Because different bulk materials and handling systems have distinct requirements, specifications are always selected according to the intended use.
Standard & Heavy-Duty
U-Panel FIBC Bags
Constructed using a continuous U-shaped fabric panel for the bottom and two opposite sides, stitched with two side panels and side-seam lifting loops for reliable structural stability.
Tubular Construction
Circular FIBC Bags
Produced from tubular fabric woven on circular looms without vertical side seams, fitted with cross-corner lifting loops and a stitched base panel suitable for fine or hygroscopic materials.
Hygienic Specifications
Food-Grade FIBC Bags
Supplied using virgin polypropylene resin and optional inner food-contact liners according to agreed hygiene, cleanliness, and customer-specified food ingredient packaging requirements.
Regulated Transport
UN FIBC Bags
Constructed according to specific UN classification requirements for the packaging and transport of regulated or hazardous solid materials where applicable.
Application-Specific Specification Notice: Not all FIBC bag types are suitable for every product or operating environment. Final bag specifications—including fabric construction, coating, liner selection, static properties, Safe Working Load (SWL), and Safety Factor—must be established according to the intended use.
Quality Focus at Every Production Stage
The suitability of an FIBC for its intended application depends on consistent quality control across raw materials, fabric construction, stitching accuracy, dimensional tolerance, lifting loops, accessories, and finished-bag performance.
For every order supplied by FIBC SILVASSA, technical specifications, Safe Working Load (SWL), Safety Factor (such as 5:1 or 6:1), and required testing are established according to customer requirements and applicable standards.
