500% Absorption. Leak-Proof Gel. DIN 55473 Certified. The global standard for eliminating container rain during ocean freight.
BENZPACK® BEDRY™ is a professional-grade calcium chloride desiccant engineered to eliminate container rain during ocean freight. It absorbs up to 500% of its own weight in moisture and binds it permanently into a stable, leak-proof gel that cannot drip or damage cargo.
Container rain occurs when temperature differentials across a voyage cause condensation to form on container walls and ceilings, then drip onto cargo. A 40ft container on a 25-day transit can deposit up to 3 litres of liquid water per day at peak condensation. BEDRY™ eliminates the moisture cycle at its source before condensation forms.

BEDRY™ operates through chemical absorption. Calcium chloride is deliquescent: it reacts with water vapour to form a stable calcium chloride brine gel. This process is thermodynamically driven and continues as long as moisture is present in surrounding air, remaining effective even at very high humidity levels where silica gel saturates.
The multi-layer laminated housing permanently retains the absorbed brine gel within the sachet through a proprietary gel-locking layer. Even at full saturation, no liquid can escape the housing under normal transit handling and vibration.
Optimal placement per DIN 55473: pole-mount units attached to container ceiling anchor points at both the door end and rear, plus one at the midpoint. This positions the desiccant directly in the path of convective air circulation where condensation-prone air accumulates. Install within 30 minutes before sealing the container.

For a 40ft container on a 25-day transit with standard cargo, 6 to 8 units of 1kg BEDRY is the baseline. For hygroscopic cargo (wooden crates, kraft-packed goods), increase to 10 to 12 units. Contact our team for a precise DIN 55473-based calculation.
BEDRY uses a multi-layer laminated housing that permanently retains absorbed moisture as a stable gel. Calcium chloride is non-toxic and non-hazardous. Use the pole-mount hanging configuration to keep units away from direct cargo contact.
Yes. BENZPACK VCI films provide molecular-level corrosion inhibition on metal surfaces. BEDRY manages bulk atmospheric moisture within the container. The two technologies are fully compatible and are the globally recommended dual-protection protocol for metal export shipments.
BEDRY BP-401 delivers up to 500% absorption for most ocean freight applications. BEDRY Ultra BP-401U is engineered for equatorial routes, transit durations exceeding 45 days, and cargo with very high hygroscopic packing material loads.
Saturated units can be disposed of as general industrial waste. Calcium chloride gel is not classified as hazardous under UN, EU, or US EPA classifications. For large volumes, dissolve in water and dispose via industrial drainage per local regulations.
