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 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 ocean transit can deposit up to 3 litres of liquid water per day at peak condensation. BEDRY™ eliminates this at source before condensation forms.

Total Cost of Ownership
A 40ft container on a 25-day transit requires 24 to 30 units of silica gel, 10 to 12 units of standard calcium chloride, or just 6 to 8 units of BEDRY™. Fewer units means lower purchase cost, less installation time, and less storage space. One rejected container shipment from moisture damage costs more than 50 times a correctly specified BEDRY™ installation. Full container calculation data is in the Technical Specifications tab above.
Where BEDRY™ Is Specified
Automotive OEM and Tier-1 component export on ocean freight routes. Heavy machinery and capital equipment in wooden crates. Cold-rolled steel coils and precision metal fabrications. Finished textiles and leather goods on long ocean voyages. Pharmaceutical bulk APIs requiring humidity control across transcontinental supply chains.
Frequently Asked Questions
How many BEDRY™ units does a 40ft container need?
For a 40ft container on a 25-day ocean transit with standard cargo, 6 to 8 units of BEDRY™ 1kg is the recommended baseline. For hygroscopic cargo such as wooden crates, increase to 10 to 12 units. Contact our technical team for a precise DIN 55473-based calculation for your cargo, route, and packing materials.
Is the calcium chloride gel safe if it contacts cargo?
BEDRY™ uses a multi-layer laminated housing that permanently retains all absorbed moisture as a stable gel. Calcium chloride is non-toxic and non-hazardous. Position units using the pole-mount hanging configuration, away from direct cargo contact.
Can BEDRY™ be used alongside VCI packaging for metal components?
Yes. BENZPACK® VCI films provide direct molecular-level corrosion inhibition on metal surfaces. BEDRY™ manages the bulk atmospheric moisture load within the container. The two technologies are fully chemically compatible and complement each other for complete protection.
What is the difference between BEDRY™ and BEDRY™ Ultra?
BEDRY™ BP-401 delivers up to 500% absorption for most ocean freight applications. BEDRY™ Ultra BP-401U is engineered for extreme conditions including equatorial routes, transit durations exceeding 45 days, and cargo with very high hygroscopic packing material loads.
How should saturated BEDRY™ units be disposed of?
Saturated units can be disposed of as general industrial waste. Calcium chloride gel is not classified as hazardous under UN, EU, or US EPA waste classifications. For large-volume operations, dissolve in water and dispose via industrial drainage per local regulations.
