Product Advantage
Adopting PP woven fabric composite PE moisture-proof film, it achieves 100% moisture resistance and resists 95%RH high humidity (simulating container condensation in sea shipping). Water vapor transmission rate ＜0.1g/㎡·24h, protecting grains and chemicals from mold. It’s a core advantage of woven fabric container moisture-proof cloth.
Longitudinal tensile strength ≥30kN/m, transverse ≥25kN/m (GB/T 3923.1-2013). No damage in 1.2m drop test (simulating loading/unloading collision), 200% more tear-resistant than ordinary plastic liners. It endures bumps and friction in transportation, meeting the needs of durable container inner liners.
Customizable for 20ft (2.35×2.39×5.9m) and 40ft (2.35×2.39×12.03m) containers. Heat-sealed edges reach 99% sealing, no moisture leakage from gaps. Installation takes 3 minutes per person without cutting, improving container moisture-proof cloth installation efficiency.
Corrosion-resistant treatment allows it to withstand PH 2-13 (simulating chemical storage). No chemical adsorption to grains, fertilizers or mineral powders. After 72-hour acid/alkali immersion test, material performance retention ≥90%, solving "corrosion damage" issues, a top choice for multi-functional container inner liners.
A 40ft liner weighs only 8-10kg (1/5 of traditional canvas), folding to 0.05m³ (like a carton). Over 50 folded liners can be stacked for empty transportation, cutting single-transport costs by 60%. Odorless and pollution-free, meeting eco-friendly container moisture-proof material standards.
Added with 0.5% UV stabilizer, after 6-month simulated outdoor storage (xenon lamp test), elongation at break retention ≥85%. It avoids "brittleness after sun exposure" of ordinary liners, maintaining good moisture resistance even in long-term yard storage, suitable for long-term storage container inner liners.

Product Uses
During 20-40 day sea voyages, its 100% moisture resistance blocks condensation (common in high-humidity shipping). With ＜0.1g/㎡·24h vapor transmission, it prevents grain mold. Lightweight (8-10kg/40ft) cuts empty-liner transport costs, ideal for bulk grain exporters.
Tolerates PH 2-13, so it won’t corrode when in contact with fertilizers (urea, phosphate). Its 99% sealed edges stop fertilizer leakage or moisture absorption. Durable (≥30kN/m tensile strength) withstands truck bumps, suitable for long-distance land hauls.
When containers are stored outdoors for 3-6 months, its UV resistance (≥85% elongation retention) prevents brittleness. Moisture-proof performance stays stable, stopping mineral powder from caking due to rain or dew—perfect for warehouse-free storage needs.
Fits 20ft/40ft containers (no on-site cutting) and installs in 3 minutes, speeding up loading at ports. It’s odorless and non-toxic, complying with international food-transport standards. Anti-tear design protects goods during rough handling at customs inspections.
FAQ
Q1: Can this liner be reused for multiple container shipments, or is it single-use only?
A: It’s reusable 3-5 times if properly maintained. After use, clean it with water (avoid chemicals) and store in a dry place—its tensile strength and moisture resistance stay stable for repeated use.
Q2: Is it safe to use with food-grade goods like edible oils or flour?
A: Yes. The PP/PE composite material is non-toxic, odorless, and meets food-contact standards (FDA-approved). It has no chemical adsorption, ensuring food goods stay uncontaminated.
Q3: Will the liner fit non-standard container sizes (not 20ft/40ft), like 45ft high-cube containers?
A: Absolutely. We offer full customization for non-standard sizes (45ft, high-cube, etc.). Just provide your container’s width, height, and length—we’ll tailor the liner to fit perfectly.
Q4: How do I fix small tears in the liner if they happen during installation?
A: Use our matching PE repair tape (included with each liner). Clean the tear area, apply the tape, and press firmly—it restores 90% of the liner’s moisture resistance and tensile strength.
