Frequently Asked Questions

Have a question? We’re here to help.

The effectiveness of a desiccant depends on its absorption capacity, intended application, and environmental conditions. For shipping containers, many container desiccants are based on calcium chloride or proprietary blends because they can absorb significant amounts of moisture—often more than three times their own weight.

  • Silica gel is excellent for smaller enclosed spaces (like sealed pouches or airtight boxes). However, for large-scale moisture control in shipping containers, calcium chloride desiccant or hybrid solutions (like HYDRY) usually offer the highest absorption and help reduce container rain and moisture damage.
  • Many container desiccants use calcium chloride and convert absorbed moisture into gel to prevent leakage.

In shipping containers, container desiccants (often packaged in desiccant bags or pouches) are the primary tool to absorb excess moisture. These moisture absorbers draw water vapor from the ambient air, lowering the dew point and minimizing condensation on container walls (often called container rain), which can lead to corrosion, mildew, and other effects of moisture.

Most container desiccants are effective for the duration of a typical shipment (often 4–8 weeks). Their longevity is influenced by:

  • Humidity levels (high relative humidity = faster saturation)
  • Temperature fluctuations
  • Desiccant type and quantity (e.g., calcium chloride vs. silica gel, and how many desiccant bags are used)

    • Under normal conditions, a well-sized desiccant setup can remain active for up to 60 days in a sealed cargo container.

To create a simple “desiccant container,” place moisture absorbers (like silica gel, clay desiccant, or calcium chloride) in breathable pouches (e.g., tyvek or kraft paper) alongside items you want to protect. Then:

  • SChoose your desiccant: Silica gel or clay desiccant for smaller spaces, or calcium chloride for heavier-duty moisture absorption.
  • Package properly: Use tear-resistant, breathable materials that prevent leakage.
  • Seal your container:Minimal exposure to outside air helps maintain low humidity.

For large shipping containers, it’s more efficient to use pre-made container desiccants—such as HYDRY—because they come ready to hang or place.

By capturing and retaining water vapor before it can condense, shipping container desiccants stop container rain (condensation on ceilings and walls). They reduce the amount of moisture in the ambient air, effectively lowering the dew point. Many (e.g., calcium chloride-based) convert absorbed water to a gel, preventing leakage and continuously controlling moisture damage.

To create a simple “desiccant container,” place moisture absorbers (like silica gel, clay desiccant, or calcium chloride) in breathable pouches (e.g., tyvek or kraft paper) alongside items you want to protect. Then:

  • Use Container Desiccants: Install HYDRY desiccant bags to manage humidity.
  • Ensure Proper Seals: Damaged doors or sealers allow humid air to enter.
  • Elevate Cargo: Place goods on a pallet or use absorbent Hypad to handle spills and any excess moisture.
  • Use Liners: Barrier bags or kraft liners can help maintain a controlled environment.
  • Monitor Humidity: Humidity indicator cards can provide a quick status check of moisture levels.

To create a simple “desiccant container,” place moisture absorbers (like silica gel, clay desiccant, or calcium chloride) in breathable pouches (e.g., tyvek or kraft paper) alongside items you want to protect. Then:

  • High Absorption: Capable of pulling in large volumes of moisture (often up to 300% of their weight).
  • Zero Leakage: Quality materials (often tyvek) prevent drips even when fully saturated.
  • Durable Packaging: Tear-resistant pouches for rough shipping conditions.
  • Reusability: Some silica gel types can be reactivated, although many calcium chloride or hybrid blends used in shipping containers are single-use due to their gelling action.

  • High Absorption Capacity: Often calcium chloride based, tackling large amounts of excess moisture.
  • Leak-Proof Technology: Converts liquid to gel, minimizing leakage.
  • Easy to Install:Comes in strips, poles, or desiccant bags that can be positioned throughout shipping containers.
  • Prevents Container Rain: Reduces dew point, stopping condensation on container walls.

  • Silica gel An excellent moisture absorber, ideal for small, enclosed, or airtight boxes.
  • Prevents moisture damage Reduces humidity, preventing mildew, corrosion, and other issues.
  • Safe for sensitive goods Inert and safe for electronics, food products, pharmaceuticals, and more.

Yes. Many desiccant products are available in various sizes, shapes, and packaging materials (e.g., tyvek, kraft, polymer) to meet specific moisture control needs. From small desiccant packets for electronics to large blanket-style solutions (like Hyblanket), customization ensures proper coverage for unique shipping requirements.

  • Cargo Sensitivity: How susceptible goods are to moisture damage.
  • Duration of Transit: Longer voyages may need higher absorption capacity and more desiccant bags.
  • Climate: High-humidity or temperature extremes demand robust solutions like calcium chloride desiccant.
  • Packaging Method: Using barrier bags, liners, or a pallet approach may reduce the total desiccant needed.
  • Monitoring: Consider humidity indicator cards.
  • Eco-Friendly: Some solutions are biodegradable if sustainability is key.
  • Leakage Concerns: Choose gel-forming or guaranteed leakproof materials if leakage is an issue.

  • Prevention of Container Rain and condensation damage
  • Protection Against Mildew and Corrosion
  • Maintaining Quality of goods like food products, electronics, textiles, etc.
  • Reduced Risk of Returns or claims due to moisture damage
  • Cost Savings from avoiding losses and preserving product integrity

A shipping container desiccant under the HYDRY brand is a specialized moisture control solution for shipping containers. HYDRY’s range (Hybag, Hypad, Hyblanket) is engineered to absorb excess moisture, lower the dew point, and prevent container rain.

HYDRY is a suite of desiccant products by Eurolog Packing Group (EPGNA) designed for shipping containers. It includes:

  • Hybag: High-capacity desiccant bags (Square, Eco, Plus+).
  • Hypad: Moisture absorbent pads for floors or pallet tops.
  • Hyblanket: A ceiling-mounted blanket that traps moisture and prevents water droplets from forming overhead.

Shipping containers can experience container rain when outside temperatures drop below the dew point of the container’s ambient air. HYDRY:

  • Eliminates condensation that causes moisture damage
  • Prevents mildew and corrosion on metal parts
  • Protects packaging and prevents product spoilage or warping

Properly installed HYDRY desiccant bags help avert:

  • Packaging Deterioration (e.g., weakened boxes, compromised seals)
  • Mold and Mildew growth on organic materials
  • Corrosion on metals or electronics
  • Caking of Powders in food products or chemicals

The required amount depends on:

  • Container Size: 20 ft. vs. 40 ft.
  • Journey Duration: Longer transit may need more desiccant bags.
  • Humidity Levels: Higher humidity or significant temperature swings might call for extra.

Manufacturers usually provide dosage guidelines—often 6–10 units for a 20-foot container and 10–16 for a 40-foot container, though this can vary.

  • Use Container Desiccants: Place or hang HYDRY products effectively.
  • Limit Ambient Air Exchange: Ensure door seals and sealers are intact.
  • Use Pads or Pallets: Absorb excess moisture with products like Hypad.
  • Insulation or Liners: Controlling temperature swings can reduce condensation.
  • Monitor and Adjust: Check conditions with humidity indicator cards if needed.

Manufacturers usually provide dosage guidelines—often 6–10 units for a 20-foot container and 10–16 for a 40-foot container, though this can vary.

Repeated from above: Typically 4–8 weeks or the length of an average shipment. The exact duration depends on climate, temperature, and how much desiccant is used. Calcium chloride blends often last the longest in high-humidity scenarios.

  • Activated Charcoal: Mild moisture absorption but not nearly as effective.
  • Bentonite Clay: A more natural alternative but lower capacity than calcium chloride or silica gel.
  • Homemade Moisture Absorbers: Rice or salt can work in a pinch but have limited effectiveness.
  • Oxygen Absorber: Note that this does not remove moisture; it only removes oxygen.

For shipping containers, these alternatives do not match the high absorption capacity of specialized container desiccants.

Rice can absorb some excess moisture, but its absorption capacity and speed are significantly lower than commercial desiccant products like silica gel or calcium chloride desiccant. While it’s occasionally used for small emergencies (e.g., a wet phone), it isn’t suitable for serious moisture control in shipping containers.
