One sheet of paper controls moisture more naturally and more powerfully.
Most silica gel ships in a plastic sachet, so “sustainable” packaging still holds plastic inside.
Select your industry to find the right product.
30+ brands already work with de:hum.
Eco-friendly paper desiccant, custom-printed with your brand.
One cellulose paper core, extended into sachets, sheets and containers for every industry.
Five desiccant types, compared on equal terms.
※ Absorption: KTR basis · Carbon: absorption-equivalent (Carbonbook) · Cost: per gram of water absorbed
Key results confirmed in accredited third-party lab reports.

Moving toward packaging that actively manages moisture.
Paper desiccants replace plastic.
Moisture control built into the packaging. No sachet.
Packaging paired with humidity data.
Founded in 2023, de:hum makes paper desiccants that replace silica gel’s environmental burden.
Custom moisture-control solutions for every industry, worldwide.

Keep garments mold-free at sea, and keep your sustainability promise.
Container condensation causes mold, stains and odor, which lead to returns and brand damage.
But the usual fix, silica gel, comes in plastic. As packaging rules tighten, it scores worse on recyclability.
Day–night swings drip condensation onto cargo: “container rain,” the main cause of mold. de:hum stops moisture layer by layer.

Paper that controls the humidity deciding shelf life, for pharma and supplements.
Every product has its own acceptable RH range. Probiotics lose potency when too dry; tablets degrade when too humid.
Silica gel only absorbs. It keeps drying past the target and can’t release moisture back, so precise humidity control isn’t possible.
※ Target RH varies by formulation.
Silica gel canisters face growing scrutiny on GMP, pharmacopoeia and environmental rules.
| Evaluation criteria | Paper desiccant | Silica gel canister |
|---|---|---|
| Humidity control | Bidirectional ERH control possible | One-way absorption only · over-drying risk |
| Safety | Zero dust · natural material | Fine particle leakage · cross-contamination |
| Packaging structure | Integrated (Cap/Bottle) possible | Separate canister insertion required |

With a floor, Cap Dry holds the target humidity. Without one, drier is better and Bottle Dry is the answer.
Cap Dry is validated for targets of RH 20% and above; below RH 20% is in validation.
A paper desiccant disc built into the lid. No canister or sachet: moisture entering at opening is caught in the cap.
Forms that target below RH 20%, such as probiotics, are currently in validation.
* Product images are concept renderings.
When a sachet or canister can’t dry the headspace enough, the container’s inner wall becomes the desiccant.
It's not the benefit of a better desiccant. It's the benefit of eliminating a component.
A liquid desiccant layer on the inner wall and base cures at room temperature in about 4 hours, invisibly.
Moisture crosses the whole container.
Stopped at the wall.
Coating happens at container manufacture, so the line needs no inserter, vision station, reject line or dryer.

Share your target humidity, container specs and distribution conditions. We’ll propose a solution.
Bidirectional humidity control for sealed enclosures with repeated temperature cycles. No power, no replacement.
IP67 housings still breathe through vents. When surfaces fall below the dew point, trapped moisture condenses.
The result is a safety risk: insulation breakdown, busbar corrosion, connector shorts, faster thermal runaway.
Too dry fails too: seals harden and crack, letting moisture back in. You need to hold humidity within a range, not just absorb.

25 hours of temperature and humidity cycling on a sealed device. Without a pack, internal RH crosses the condensation line (RH 80%) every cycle; with Smart Dry it stays at RH 60–72%.
* Chart based on de:hum measured data. Results depend on housing design and operating conditions.
Temperature cycles cause condensation in every sealed EV component, from headlights to battery packs.
Wherever a sealed space heats and cools, the same principle cuts condensation.
We reproduce what vehicle components go through inside the chamber to verify Smart Dry.
Repeats temperature cycles to reproduce condensation inside housings.
Long-term exposure to heat and humidity to check for performance loss.

Follow on LinkedInPPWR has taken effect across all 27 EU member states. Paper recycling rate 83% vs plastic 41% — the numbers show the direction. Note: "paper-look" packaging with a plastic liner is not recyclable. Desiccants are included.
Read on LinkedInde:hum Max Dry is SGS-tested 100/100 "Good recyclability" — passing all 4 criteria with zero waste residue. A single silica gel sachet can drag down the grade of the entire pack.
64% of companies now evaluate suppliers on sustainability (up from 38% in 2020). Your packaging is part of your buyer's Scope 3. de:hum cuts carbon by about 80% for the same absorption capacity and provides carbon footprint data.
The European Commission's PPWR Q&A explicitly lists "desiccant bags". The definition is function-based: if it protects a product from moisture, it's packaging. Silica gel is a penalty; de:hum is recyclable fiber.
Consumers punish half-measures. A plastic desiccant sachet hidden inside a sustainable paper box — that's exactly what people now notice. de:hum is genuine fiber all the way through.
Nestlé's list of packaging being phased out includes materials that look recyclable but aren't. Silica gel in poly-coated sachets fits that profile exactly. de:hum is biodegradable and recyclable.
Fees are calculated across the whole pack. A non-recyclable silica gel desiccant quietly pushes fees up. de:hum keeps the whole pack — and the cost — low. Recyclability is now a cost line item.
Amazon cut plastic in its boxes from 65% to 27%. But that doesn't reach inside the box. Silica gel still takes up 3–4× the space and weight. de:hum carries "use less" all the way inside the box.
All of them pivoted to paper — not because they lost ambition, but because they got tired of waiting for recycling infrastructure. Paper is the one stream that already works. It's time to put the last piece, the desiccant, into the paper stream too.
Silica gel absorption: 30–35%. de:hum paper desiccant: 135–155% — about 4×. Less desiccant per pack means lower space, shipping weight, and cost. The same protection, a smaller footprint.
