Export Moisture-Control Packaging Solution: Material Combination and Execution Boundaries for Ocean Shipping Scenarios

Shengde Materials (Dalian) Co., Ltd. develops the export moisture-control packaging solution targeting the high-humidity, large temperature difference characteristics of transoceanic shipping, providing actionable implementation references for procurement, engineering and supply chain teams to reduce risks of cargo moisture deterioration and packaging deformation during ocean transportation.

Material Combination Framework of Export Moisture-Control Packaging Solution for Ocean Shipping

Adaptation Rules for Multi-layer Packaging Structure

For cargo with moisture-proof requirements, the inner layer can be sealed with barrier moisture-proof film, matched with desiccant units of corresponding specifications adapted to the moisture content of the cargo itself and the internal space volume of the package. The middle layer can use moisture-proof corrugated cardboard as a buffer and secondary barrier structure, and the outer layer adopts waterproof and weather-resistant cartons that meet export standards.

Execution Boundaries and Application Notes of the Solution

This solution is applicable to conventional sea container transportation scenarios with a voyage of 15 to 90 days, and is not applicable to open-top transportation without sealed containers and ultra-long-distance transoceanic transportation scenarios with a voyage of more than 90 days. Key implementation notes:

1. Packaging operations should be completed in a workshop environment with relative humidity lower than 60% to avoid water vapor entering the sealed package during operation;
2. The dosage of desiccant should be adjusted according to the internal space volume of the package, initial moisture content of the cargo, and average humidity parameters of the route, and fixed dosage standards should not be directly applied without adjustment;
3. Moisture-proof signs should be pasted on the surface of the outer carton to remind storage and loading teams to avoid open-air stacking.
