In the realm of industrial packaging, FIBC Bulk Bags—also known as Jumbo Bags or Ton Bags—are essential for handling and transporting large quantities of materials. These versatile bags are used across various industries, including agriculture, construction, and chemicals, due to their strength, durability, and capacity. At VidePak, we leverage cutting-edge technology and precise manufacturing processes to produce high-quality FIBC Bags that meet the highest standards of performance and reliability.
What is FIBC Bulk Bags? (Definition & Aliases)
FIBC Bulk Bags—Flexible Intermediate Bulk Containers—are liftable, collapsible packaging systems designed to move hundreds of kilograms to multiple tons safely in a single unit. Built on woven polypropylene (PP) textiles and tuned with optional liners, coatings, baffles, and static‑control grids, FIBC Bulk Bags appear simple yet operate as a tightly coupled system. In procurement and standards you will also meet their aliases: big bags, jumbo bags, super sacks, ton bags, and UN performance‑tested variants coded 13H1–13H4 for dangerous goods. Different names, same promise: concentrated capacity, controlled handling, credible compliance.
From a field‑knowledge perspective, FIBC Bulk Bags sit where polymer rheology (melt‑flow index, antioxidant/UV packages) intersects textile mechanics (tape denier, fabric gsm, seam architecture), where lifting design (loop geometry, load paths) meets electrostatics (Type A/B/C/D per IEC 61340‑4‑4), and where regulatory frameworks (ISO, UN Model Regulations, ADR/IMDG/IATA) meet food‑contact law (FDA 21 CFR §177.1520, EU No 10/2011, EC No 2023/2006). Hygiene systems are audited under BRCGS Packaging Materials, Issue 7 or ISO 22000:2018/FSSC 22000.
Horizontal and vertical analysis. Horizontally, textiles lend tenacity and seam logic; lifting engineering disciplines sling angles and stress; electrostatics governs ignition risk; powder science explains de‑aeration and flow; logistics defines stacking, racking, and containerization. Vertically, cause and effect stack: resin → tape → fabric → panel set → seam → loop → bag geometry → pallet/container behavior. Turn one dial and the melody shifts—raise tape denier and tensile climbs but pliability declines; introduce baffles and cube utilization rises yet discharge dynamics change; move from Type B to Type C static control and safety expands in explosive atmospheres while grounding discipline becomes mandatory.
Data reinforcement. Commercial corridors visible on Made‑in‑China/Alibaba and industry peers consistently show: Safe Working Load (SWL) 500–2,000 kg, fabric 160–240 g/m² uncoated or 180–260 g/m² coated, tape 850–1,600D, safety factor 5:1 (single trip) or 6:1 (multi‑trip), body dimensions around 85–100 cm square × 90–120 cm height; liners typically 50–100 μm (LDPE/LLDPE) in tubular or form‑fit geometry. Performance anchors include ISO 21898:2024 for FIBC testing and UN Model Regulations 6.5.6 (top‑lift, drop, topple, stacking, righting).
Case analysis. A starch processor migrating from 25‑kg valve sacks to FIBC Bulk Bags configured at 1,000 kg SWL, 5:1, cross‑corner loops, baffle panels, and a 70 μm form‑fit liner eliminated ~60% of forklift touches, widened aisles, cut dust complaints, and lowered export pallet counts through higher cube efficiency.
Comparative study. Palletized small bags win on SKU granularity but punish labor; rigid IBCs stack hard but demand costly returns; FIBC Bulk Bags occupy the middle ground—collapsible after emptying, lift‑ready during use, cost‑smart at scale. For a concise product window, see FIBC Bulk Bags.
What is the features of FIBC Bulk Bags? (Strength, Safety & Static Control)
Load‑bearing architecture. Woven PP delivers high tensile with controlled elongation; double‑folded hems and chain/lock stitches convert fabric strength into system strength. Safety factors 5:1 (single use) and 6:1 (multi‑use) are routine, with UN‑tested designs proving out under drop, topple, and stacking.
Filling and discharge versatility. Spout tops meter powder; duffle or conical tops speed volumetric fills; discharge options range from plain to full‑open to spouted. Add internal baffles and the footprint stays square, lifting container and trailer utilization by 10–25% compared with tubular bodies. The result is not just more product per box, but calmer stacks, cleaner aisles.
Static‑control classes (IEC 61340‑4‑4). Type A (no electrostatic protection) suits non‑flammable environments; Type B reduces propagating brush discharges via low breakdown‑voltage fabric; Type C uses a conductive grid that must be grounded during fill/empty; Type D dissipates charge without a ground through vendor‑specific chemistries. The wrong class in a dusty solvent area is not an inconvenience—it is an ignition source.
Barrier and hygiene options. PP coatings (~20–40 μm) narrow sifting; liners (50–100 μm LDPE/LLDPE) curb moisture and aroma; form‑fit liners reduce folds and dead zones that trap residuals. Food‑contact declarations align with EU No 10/2011 and FDA 21 CFR §177.1520; site controls under BRCGS add foreign‑matter prevention, pest management, allergen assessments.
Outdoor resilience. UV stabilization packages around 150–300 kLy (or supplier‑declared ASTM G154/G155 exposure hours) help resist embrittlement in yards. Anti‑slip coatings and dust‑proof seams support tall, straight stacks under radiant‑heat roofs.
Horizontal/vertical analysis. Horizontally, compare FIBC Bulk Bags with corrugated gaylords (no loops, more pallets) and with steel IBCs (high capex, return logistics). Vertically, micro choices—gsm, stitch density, loop angle, liner gauge—accumulate into macro outcomes: allowable stack height, discharge time, residual levels, and claim rates.
Data reinforcement. Fabric gsm 180–220 commonly supports 1,000–1,500 kg SWL; loop systems are designed to exceed 2× SWL to accommodate sling angles; dust‑proof seam tape appears repeatedly in RFQs where sifting is a chronic complaint.
Case analysis. A fertilizer blender in humid coastal lanes adopted coated fabric (~30 μm PP), corner baffles, and anti‑slip bottoms; caking incidents fell, lean decreased, forklift rework receded.
Comparative study. Against palletized paper multiwall units, FIBC Bulk Bags slash unit counts by 20–40×, simplify batch traceability, and reduce contamination vectors from repetitive decanting. Against thin‑liner octabins, woven PP holds geometry better under summer heat.
What is the production process of FIBC Bulk Bags? (From Resin to Lift‑Ready)
Resin preparation & tape extrusion. Polypropylene—optionally with qualified rPP—is compounded and extruded into slit tapes. Melt‑flow index is trended under ASTM D1238 to balance die pressure and draw windows; antioxidant/UV packages are verified against supplier CoAs.
Orientation & weaving. Tapes are stretched to elevate crystallinity and tenacity, then heat‑set for dimensional stability. Circular or shuttle looms weave fabrics to target denier and gsm; pick density and tape uniformity determine puncture resistance and seam efficiency.
Coating & lamination (as required). PP coatings (20–40 μm) or PP/BOPP laminations raise sifting control and printability; surface energy is held at ≥38 dynes for ink anchorage.
Panel cutting & loop fabrication. Body panels, reinforcement patches, and lift loops (side‑seam, cross‑corner, single/dual) are cut. Loop webbing width and stitch count are matched to SWL and sling angle; mis‑sizing here is paid back as loop failure later.
Sewing & reinforcement. Chain/lock stitch patterns, double‑folded hems, and reinforcement patches convert textile capacity into finished‑bag performance. Dust‑proof seam tapes and overlocking are specified according to fines and flow.
Liner manufacture & insertion. Liners—LDPE/LLDPE 50–100 μm; form‑fit or tubular—are blown/cast and inserted; seal windows (temperature/time/pressure) are mapped to resin blend and equipment family to avoid brittle or weak seals.
Printing & identification. Safety marks, SWL, safety factor, electrostatic class, and UN codes (where relevant) are printed. Color ΔE targets and rub/scuff resistance (e.g., ASTM D5264) keep legibility through transport.
Quality checkpoints & testing. Fabric tensile (ASTM D5035), seam efficiency, and the FIBC suite (top‑lift, drop, topple, stacking) per ISO 21898:2024, with UN 6.5.6 where applicable. Electrostatic verification follows IEC 61340‑4‑4 (Type B/C/D). Food‑contact migration is shown to EU No 10/2011; hygiene is evidenced under BRCGS Issue 7/ISO 22000.
Horizontal and vertical analysis. Horizontally, the line borrows dyne control from film converting, uptime playbooks from textile mills, and HACCP zoning from food plants. Vertically, drift propagates: under‑drawn tapes lead to creep; low stitch density to seam splits; mis‑set seal curves to liner failures; poor grounding discipline to static hazards. A factory is a choir—one flat voice spoils the harmony.
Data reinforcement. Capability is held via SPC on MFR, dyne meters on coaters, loop/needle wear metrics, and periodic destructive testing that stays comfortably above acceptance criteria.
Case analysis. After installing live dyne telemetry and tightening loop stitch‑count windows, one partner more than halved print defects and pushed loop failure rates below 0.1%—small changes, big dividends.
Comparative study. 5:1 single‑trip designs pull cost per move down; 6:1 multi‑trip holds up in closed loops; UN‑tested bags unlock regulated lanes. Pick the lane; then pick the bag.
What is the application of FIBC Bulk Bags? (Core Industries & Material Flows)
Food & agri ingredients. Sugars, rice, flour, starches, pulses, malt, and salt demand cleanliness and predictable discharge. FIBC Bulk Bags with form‑fit liners (~70–90 μm) and dust‑proof seams protect against contamination; baffles stabilize stacks in ambient warehouses, reducing lean and rework.
Chemicals & minerals. Resins, pigments, TiO₂, calcium carbonate, fertilizers, silica—abrasive, dusty, sometimes flammable when airborne. Type C or D FIBC Bulk Bags mitigate ignition risk during high‑rate fill/empty cycles; coated fabrics and reinforced spouts reduce sifting at transfer points.
Construction & energy. Sand, cement, gypsum, pellets, and biomass drive high shear at seams and loops. Coatings restrict dust; full‑open or conical discharge accelerates decanting at mix points; robust webbing tolerates telehandler abuse.
Recycling streams. Regrind plastics and shred feedstocks value abrasion‑resistant fabrics and labeled SWL for safe crane lifts in yards. Collapsibility after discharge frees backhaul capacity, a quiet but material P&L impact.
Data reinforcement. Common SKUs: 1,000 kg SWL (90×90×110 cm) baffle bags for food powders; 1,500 kg SWL (95×95×120 cm) for minerals; Type C with grounding tabs for solvent‑classed plants; liners 60–100 μm for hygroscopic powders.
Case analysis. A maltster replaced five 200‑kg drums with FIBC Bulk Bags using conical tops and spouted bottoms; fill rates increased, forklift miles fell, brewhouse dust complaints softened.
Comparative study. Versus drums: fewer units, fewer barcodes, fewer touches. Versus rigid bins: lower capex, lower backhaul, better space yield post‑empty. The right bag often beats the wrong bin.
What is the application of FIBC Bulk Bags? (Export, Compliance & Supply Chain Physics)
Cross‑border readiness. UN Model Regulations mark‑ups (13H codes), ISO/UN test certificates (top‑lift, drop, topple, stack), and electrostatic class documentation shorten approvals across ADR/IMDG/IATA routes. Food‑contact dossiers (DoC, migration) help pass retailer audits in EU/UK/US without drama.
Containerization & cube. Baffled FIBC Bulk Bags hold near‑square, improving 20‑/40‑ft container space utilization; anti‑slip coatings and corner reinforcements tame lean, while tie‑downs/dunnage keep stacks honest at sea.
Warehouse climate. Hot roofs accelerate creep; coated fabrics and correct gsm preserve geometry; UV packages endure in yard staging. Pallet patterns (2×2, 3×2) are proven via compression trials before SOP freeze.
Data reinforcement. Export RFQs regularly ask for ISO 21898 and UN 6.5.6 reports, electrostatic class certificates (IEC 61340‑4‑4), and liner seal windows. Traceability (lot → roll → panel set → finished bag) and pest/allergen risk assessments under BRCGS have become routine asks.
Case analysis. A fertilizer exporter moving through tropical ports adopted coated, baffled FIBC Bulk Bags with anti‑slip bottoms; container lean incidents dropped and claim rates slid below 0.2% per 10,000 bags.
Comparative study. Where hermetic oxygen barrier is mandatory (oxidation‑sensitive powders), EVOH/foil liners may be mandated; where stack height and handling dominate, PP fabric + PE liner typically wins on cost‑to‑performance.

Understanding FIBC Bulk Bags
FIBC Bulk Bags are flexible intermediate bulk containers designed to carry bulk materials in a secure and efficient manner. These bags are typically constructed from woven polypropylene, providing a robust solution for handling heavy and granular materials. Their design includes features such as reinforced lifting straps, top and bottom closures, and optional liners for added protection against moisture and contamination.
The Production Process at VidePak
At VidePak, the production of FIBC Bulk Bags involves a meticulous process that ensures every bag meets stringent quality standards. Our manufacturing process incorporates state-of-the-art equipment provided by Starlinger, a global leader in packaging technology. Here’s a detailed look at the steps involved:
1. Extrusion and Fiber Production
The process begins with the extrusion of polypropylene resin into fibers. This step is crucial as it determines the strength and durability of the final product. The polypropylene is melted and formed into thin strands, which are then cooled and solidified. These fibers are the foundation of our Aluminum Jumbo Bags, providing the necessary strength to withstand heavy loads.
2. Weaving
The extruded fibers are woven into a fabric using advanced circular looms. This weaving process creates a strong, flexible material that forms the body of the FIBC Bulk Bags. Our circular looms, supplied by Starlinger, ensure precise and consistent weaving, resulting in high-quality fabric with excellent load-bearing capacity.
3. Cutting and Sewing
Once the fabric is woven, it is cut into the appropriate sizes and shapes for the bag components. The cut pieces are then sewn together using heavy-duty stitching machines. This stage involves assembling the bag’s body, lifting straps, and any additional features such as discharge spouts or linings. Our sewing machines, also provided by Starlinger, are designed to handle the heavy-duty nature of the fabric, ensuring strong and reliable seams.
4. Printing and Coating
To enhance the functionality and aesthetics of our FIBC Bags, we incorporate advanced printing and coating techniques. Printing is used for branding, labeling, and providing handling instructions. Our printing technology ensures high-resolution graphics and durable ink that remains legible throughout the bag’s lifecycle. Additionally, coating processes are applied to provide additional protection against environmental factors such as UV rays and moisture.
5. Inspection and Quality Control
Quality control is a critical component of our manufacturing process. Each batch of Jumbo Bags undergoes rigorous inspection to ensure it meets our quality standards. We test for various parameters including tensile strength, seam integrity, and dimensional accuracy. Any bags that do not meet our stringent criteria are discarded or reworked to ensure only the highest quality products reach our customers.
6. Packaging
Once the bags pass inspection, they are folded, packed, and prepared for shipment. Our packaging process is designed to protect the bags during transportation and ensure they arrive at their destination in optimal condition. We use specialized handling equipment and packaging materials to prevent damage and maintain the integrity of the Ton Bags.
