Yes. Reactivate silica gel by heating at 120°C (250°F) for 1–2 hours to release moisture.
Can silica gel be reused?

Should we seal off the vents in a container when installing container desiccants?
Yes, seal off the vents – this will ensure no “new” air is introduced into the shipping container during the voyage.
What is a shipping desiccant, and how does it work?
A shipping desiccant is a moisture-absorbing product used in shipping containers, warehouses, and storage facilities to prevent condensation, mould, rust, and packaging damage. It works by absorbing excess humidity from the air, reducing the risk of container rain, and keeping cargo dry throughout transit.
Why do I need desiccants for my shipping container?
When cargo is sealed inside a shipping container, temperature fluctuations cause moisture to condense, leading to:
mould and mildew growth on textiles, food, and paper products.
Rust and corrosion on metal parts and machinery.
Warpage and swelling in wooden products and furniture.
Packaging deterioration, weakening cartons, labels, and shrink wrap.
Using high-quality container desiccants helps prevent moisture-related cargo damage, ensuring safe delivery and product integrity.
How many desiccants do I need for my shipping container?
The amount of container desiccant required depends on:
Container size (20ft vs. 40ft).
Cargo type (wood, textiles, food, machinery, etc.).
Humidity levels along the shipping route.
Shipping duration (short-term vs. long-term storage).
General Desiccant Usage Guide:
20ft Container → 4 to 8 desiccant bags
40ft Container → 8 to 16 desiccant bags
High-humidity shipments → Additional desiccants for extra protection.
For precise desiccant recommendations, consult Protection Experts Australia for customized moisture control solutions. It all depends on the type of shipping desiccant and its absorption rate.
How do I place desiccants inside a shipping container?
For maximum effectiveness, place container desiccants as follows:
Hang desiccant bags along container walls to capture moisture as it rises.
Distribute evenly around cargo for balanced absorption.
Avoid floor placement, as standing water can reduce effectiveness.
Allow the desiccant to have room to absorb moisture in the air, and avoid having cargo sitting directly against the hanging desiccant.
How long do desiccants last in a shipping container?
The effectiveness of shipping desiccants depends on humidity levels, temperature changes, and cargo type.
Standard usage lifespan: 45 to 90 days
High-humidity shipments: Additional desiccants may be required for extended protection
Can desiccants leak or damage my cargo?
Quality container desiccants are designed to absorb moisture safely without leaking.
Pro-Ex Gel 1kg converts absorbed water into a gel-like substance, preventing spills.
Non-leak desiccant pouches ensure moisture is trapped without harming cargo.
For high-value shipments, choosing leak-proof desiccants from Protection Experts Australia prevents moisture damage and contamination.
Do desiccants work in extreme weather conditions?
Yes – Industrial-grade desiccants are designed for:
Tropical and humid climates where condensation is high.
Cold environments where temperature fluctuations increase moisture risk.
Ocean freight and long-distance shipments with prolonged exposure to varying temperatures.
Using high-performance desiccants like Pro-Ex Gel 1kg ensures that cargo stays dry in all conditions.
Are desiccants safe for use with food and pharmaceuticals?
Yes, but it depends on the type of desiccant and packaging method:
Food-safe desiccants are indirect moisture absorbers designed for use inside shipping containers without direct contact with food.
Silica gel desiccants are commonly used in pharmaceutical packaging for controlled humidity levels.
