Moisture-Resistant Export Shipping Cartons
Built to Withstand Ocean Freight, Extreme Humidity & Container Rain
Ocean containers endure extreme temperature cycling, creating ceiling condensation that drips onto cargo stacks ('container rain'). Standard corrugated boxes absorb this moisture, lose 70% of their stacking strength, and collapse. TopWay's Export Packaging combines hydro-resistant sizing, water-repellent barrier coatings, and moisture-proof adhesives to ensure cartons remain rock-solid across 45-day sea voyages.
Engineered for Reliability & Efficiency
Manufactured with certified industrial polymers and high-tensile virgin paper at TopWay's Sitapura facilities.
Calibrated Cobb 60 Barrier
Exterior kraft liner sheds surface condensation with water absorption ratings under 30 g/m².
Anti-Fungal & Mold Shield
Treated with eco-compliant antimicrobial agents that prevent mold, mildew, and odor formation.
Sea-Freight Humidity Endurance
Retains over 85% structural stacking rigidity even in 90%+ relative humidity maritime conditions.
