Industrial enterprises operating continuous mineral leaching plants, large-scale paper pulp mills, and municipal water treatment infrastructure require bulk chemical packaging engineered for structural resilience and high-volume discharge. Our caustic soda jumbo Flexible Intermediate Bulk Containers (FIBC) offer the ultimate packaging solution for enterprise procurement directors seeking to balance container payload efficiency with workplace EHS safety standards. By sourcing directly from a primary Chinese chlor-alkali manufacturer operating an annual production capacity of 120,000 metric tons, your facility secures guaranteed raw material continuity while eliminating intermediary commercial markups.
Manufactured just 15 kilometers from Tianjin Port, our heavy-duty 1000kg and 1200kg bulk bag configurations are loaded into 20ft full container loads (FCL) for rapid dispatch to global industrial destinations.


Every caustic soda jumbo unit dispatched from our production complex contains certified anhydrous sodium hydroxide engineered for immediate industrial dissolution:
● High-Purity Spherical Pearls in Bulk Bags: Featuring uniform micro-spherical geometry that eliminates internal bridging, allowing fluid, continuous gravity feeding in automated loss-in-weight silo systems.
● Rapid-Dissolving Anhydrous Flakes in Bulk Bags: Engineered with maximum surface area for instant exothermal dissolution in heavy industrial mixing tanks and leaching vats.
● Low Carbonate and Heavy Metal Tolerances: Strict quality control during membrane cell electrolysis ensures trace iron and residual sodium carbonate levels remain well below international industrial limits.


Transporting thousand-kilogram chemical units across ocean routes requires rugged, moisture-sealed packaging built to handle extreme mechanical stresses and ambient atmospheric humidity. Every bulk sack leaves our factory fully protected for safe long-distance transit and extended warehouse storage.
Key features of our bulk packaging include:
1. Reinforced Polypropylene Outer Shell: Fabricated from heavy-gauge woven polypropylene with cross-corner lifting loops, designed to withstand intense tensile strain during crane hoisting and forklift stacking.
2. Heavy Polyethylene Inner Liner: Features a thick, heat-sealed inner PE liner that creates a complete barrier against airborne moisture, preventing chemical caking or degradation during sea voyages.
3. Dual Discharge & Filling Spouts: Top filling spouts and bottom discharge chutes are equipped with secure tie-offs to maintain a dust-controlled environment during loading and plant unloading.
Optimizing landed supply costs relies on maximizing container space and accelerating customs dispatch. Our Tianjin factory logistics operation delivers:
● Maximized 20ft Container Weight Allowance: Container stowage plans are engineered to fit up to 28 metric tons net chemical weight per 20ft FCL container, drastically reducing ocean freight costs per landed metric ton.
● Immediate Terminal Port Access: Located 15 kilometers from Tianjin container berths, enabling fast port staging, rapid export customs clearance, and priority vessel loading.
● Palletized or Direct Cargo Placement: Available with ISPM-15 compliant heat-treated wooden pallets for forklift handling or direct container floor stowage for maximized payload weight.
