Products Description

Core Advantages of Sodium Hydroxide FIBCs: Exceptionally high loading/unloading efficiency, labor-saving; Excellent sealing properties, moisture-proof and anti-caking; Suitable for long-distance transport and export shipping; Eligible for UN hazardous packaging certification, meeting maritime and land transport requirements for Class 8 corrosive substances; Safe and reliable, minimizing leakage risks.

1. Standard Construction: Outer layer of PP polypropylene woven fabric (base fabric weight ≥110g/m², meeting tensile strength standards) + PE inner liner (thickness ≥0.20mm, sealed to prevent moisture and leakage). Direct loading without inner liner is strictly prohibited. For powder/ultrafine granule alkali, an additional heat-sealed PE bag is recommended. UN packaging certification requires full-body welding with no pinholes.

2. Alkali-Resistant Materials: PP/PE exhibits strong chemical inertness and withstands concentrated alkalis. Ordinary cotton fabric or paper liners are strictly prohibited. Sealing rings should prioritize EPDM/FKM. Lifting straps are high-strength PP, featuring four lifting points + cross-bottom support with a safety factor ≥5:1 (mandatory for hazardous chemicals, far exceeding the standard 1.8).

3. Common Specifications: Primarily 1000kg (1 ton), typically 90×90×110cm; also available in 1200kg. Top/bottom loading ports (with tie-in/flange) facilitate mechanical filling/unloading. Optional UV-resistant masterbatch (mandatory for outdoor storage ≥3 months) and anti-static coating (for dry dusty environments).
