Desiccants for Containers: Signode’s Hygro-Gel and Dri-Pack Solutions
November 11, 2025
Moisture damage during container shipping is a silent threat to global trade. Condensation inside containers, commonly known as “container rain” can lead to corrosion, mold growth, and packaging deterioration. For businesses shipping goods across varying climates, moisture control is critical.
Signode offers two advanced desiccant solutions tailored this solution: Hygro-Gel and Dri-Pack. These products provide reliable protection against humidity and condensation, allowing cargo to arrive as expected.
Why Does Moisture Control Matter?
When containers travel through different temperature zones, humidity inside can condense on walls and ceilings. This water drips onto cargo, causing:
- Rust and corrosion on metal parts
- Mold and mildew on textiles and food products
- Packaging deformation and label damage
