ES K Container Desiccant Bags for Long-Distance Shipping
During export shipments, cargo may remain closed inside a shipping container for many days or weeks. During this time, ambient temperature changes, and so do the humidity conditions inside the cargo space. Water vapour may come not only from the air, but also from pallets, cardboard boxes, interlayers, protective packaging materials and the transported goods themselves. ES K container desiccant bags are used to bind excess moisture in the cargo space. In practice, they support cargo protection against condensation, wet packaging and moisture-related damage that may become visible only after delivery.
When Does Moisture in a Shipping Container Become a Problem?
The problem becomes more significant on long routes, during changes in climate zones and when there are large temperature differences between day and night. When the walls or ceiling of the container become cooler than the air inside, water vapour may condense on these surfaces in the form of droplets. Such conditions are especially unfavourable for metal components, machinery parts, products packed in cardboard boxes, goods placed on wooden pallets, textiles and cargo for which moisture may lead to complaints, loss of commercial quality or additional costs for the consignee.
How Do ES K Container Desiccant Bags Work?
ES K container desiccant bags have the form of hanging bags with a mounting hook. The filling is based on bentonite clay impregnated with calcium chloride, a sorbent material designed to bind moisture from the air. After being hung inside the container, the bags work in the cargo environment and adsorb part of the water vapour present in the transport space. In practice, this helps reduce the effects of temperature changes, condensation on cold surfaces and deterioration of packaging condition during transport.
What Should Be Considered Before Loading?
Desiccant bags should be treated as part of shipment preparation, not as a last-minute addition. In containers loaded with pallets, access to the side walls may quickly become limited, so the placement of the bags should be planned before loading starts or carried out step by step during loading. Before closing the container, it is worth checking whether the interior is dry, whether pallets and packaging are not damp, and whether the bags will not be crushed, covered or damaged by the cargo. The desiccant bags should have as much free contact as possible with the air inside the cargo space.
