Desiccant Blanket 2 kg: Best-Practice Guide
The 2 kg blanket, on top of the cargo
How to use the 2 kg SECAL desiccant blanket to protect your cargo from condensation. It goes on top of the load thanks to its laminated back. Placement, dose and sound practice.
1. The product
The 2 kg SECAL blanket is a large-surface desiccant that sits on top of the cargo. Its laminated back stops the gel ever touching the product, while its breathable upper face captures the moisture in the container air. It is the answer when the cargo is stacked high or there is no room to hang desiccants on the walls.
2 kg, real
A high-capacity blanket for whole-container protection.
Laminated back
It sits on the cargo without marking the product.
Large surface
It absorbs fast and evenly across its whole upper face.
How it works: the blanket captures the moisture in the air — container rain — and holds it as a gel, with no dripping. The laminated face goes against the cargo; the absorbing face stays upwards and clear.
2. Kilos that actually protect: 1.6 kg of active ingredient
What protects your cargo is not the total weight of the blanket but the active ingredient: the calcium chloride that really absorbs the moisture. The 2 kg SECAL blanket carries it in the right proportion.
| Component | Share | What it does |
|---|---|---|
| Calcium chloride | 80% — 1.6 kg | The component that absorbs the moisture |
| Gelling starch | 20% — 0.4 kg | Turns the water into gel so it cannot drip |
Not all blankets weigh the same. A lighter blanket carries less active ingredient even when it costs about the same. When you compare, look at the kilos of calcium chloride, not just the format.
3. When the blanket format is the right answer
Cargo stacked high
When no room is left between the cargo and the walls to hang anything.
No lashing rings
In containers or units with no rings on the walls.
Fast installation
It is laid on the pallets or sacks as you load, so set-up takes less time.
4. Placement: on top, absorbing face clear
The blanket rests on the cargo with one clear orientation: laminated face towards the product, absorbing face upwards.
Do this
- Resting on top of the cargo or the pallets
- Laminated face down, towards the product
- Absorbing face upwards and clear
- Spread along the length of the container
- Leaving the recommended gap to the roof
Not this
- Absorbing face turned downwards
- Anything laid on top covering the upper face
- All of them piled at one point
- Crushed under other cargo
- Loading with the product or the container damp
5. How many blankets per container
Because of their capacity, few blankets are needed per container. The dose depends on the volume, on the moisture of the cargo and its packaging, on the route and on the voyage length.
| Container | Low risk | Medium risk | High risk |
|---|---|---|---|
| 20 ft | 3 blankets | 4 blankets | 5 blankets |
| 40 ft | 5 blankets | 7 blankets | 9 blankets |
| 40 ft HC | 6 blankets | 8 blankets | 10 blankets |
2 kg SECAL blankets. Low risk = dry cargo and short route; high = tropical or monsoon route, or a long voyage of 30–60 days. Spread the blankets along the cargo for even absorption.
6. Frequent questions
Can the blanket really sit on the cargo?
Yes — that is what it is designed for. The laminated back separates the gel from the product. The only rule that matters is that the absorbing face, the upper one, must stay clear.
How is it different from the 750 g unit?
The 750 g unit is made to hang from the rings or the top rail and suits most loads. The blanket is for cargo stacked high, containers with no rings, or when you want to set up faster with fewer pieces.
Why compare active ingredient instead of total weight?
Because the calcium chloride is what absorbs. A blanket sold as 2 kg with a lower share of active ingredient holds less water for the same money.
Can I combine blankets with hanging units?
Yes, and it is often the best approach: blankets over the cargo and 750 g units at the door area, where condensation concentrates most.
