Paper-based eco desiccant

Control Moisture,
Naturally.

One sheet of paper controls moisture. ~4× the absorption of silica gel. Single-material recyclable.

Scroll
The problem

One desiccant,
one plastic sachet.
It doesn't have to be this way.

Most silica gel is sealed in plastic sachets and discarded with the product. Low absorption, high volume, and hard to recycle.

A brand's sustainability message and the plastic desiccant inside the packaging contradict each other.

Find your fit

Every industry has
a different moisture problem.

That's why desiccants need to change too. Select your industry to find the right product and application method.

The technology

One paper absorption core,
one platform.

At de:hum's core is a cellulose-based paper absorption core. Kraft paper on the outside, white cellulose fiber inside — drawing in moisture.

This core is extended into sachets, sheets, and containers to meet industry-specific requirements.

  • Smart DryTwo-way ERH control. Designed to a target humidity
  • Bottle DryContainer-integrated extension line

※ Absorption: Max Dry is measured per KTR testing; calcium chloride per deliquescence equilibrium (long-term). Test conditions differ, and the gap may narrow under identical conditions.
※ Carbon reduction: cradle-to-grave (raw materials, manufacturing, disposal), absorption-equivalent basis. de:hum values are verified data; competitor values are estimates from published literature.
※ Calcium chloride liquefies after absorbing moisture and requires a separate container or tray, which is reflected in its safety and recyclability scores.

Protect what you ship. Protect the planet.

Protecting garments from moisture and mold during ocean shipping — while keeping your brand's sustainability promise.

The challenge

Conventional desiccants will always saturate.

During long-haul ocean shipping, condensation inside containers leads to mold, stains, and odors — causing returns and brand damage.

But the solution used until now, silica gel, comes in plastic packaging. As global packaging regulations tighten, it will soon no longer be an option.

Why you can't wait

Conventional desiccants will always saturate.

EU · Japan · Korea — plastic packaging regulations are tightening simultaneously in key markets. Silica gel fails every standard.

Target humidity design. Integrated package.

Precisely controlling the humidity that determines the shelf life of pharmaceuticals and health supplements — with paper.

The challenge

Too high or too low — both fail.

Every drug has its own acceptable relative humidity (RH) range. Probiotics die if they get too dry; tablets dissolve if they get too humid. Quality is guaranteed only within the target humidity range.

Silica gel is a one-way desiccant that only absorbs. It keeps pulling in moisture and causes over-drying, and it cannot release moisture back to hold a target level. The precise humidity control pharma requires is impossible.

reach RH 0%

For some products, headspace humidity won't come down with a sachet or a canister.
With Bottle Dry, the container's inner wall itself becomes the desiccant.

Condensation in sealed spaces,
controlled by paper for 10 years.

Battery packs, cameras, lights, electronics — controlling condensation in sealed spaces with repeated temperature cycles using bidirectional paper material.

The challenge

Every temperature cycle
crosses the dew point.

Even IP67-sealed housings breathe in humid air through breather vents. The moment the temperature difference between the cooling channels and cell surfaces drops below the dew point, trapped moisture turns into condensate.

The result: insulation breakdown, busbar corrosion, connector shorts, and accelerated thermal runaway — issues directly tied to safety.

Why existing solutions fail

Conventional desiccants will always saturate.

Not a material that absorbs more — one that self-regenerates without saturation.

Application scope

Beyond batteries, it applies to three core systems.

Temperature cycles inside EVs — from headlights to cameras to battery packs — cause condensation in every sealed component. Smart Dry is customized for each system.

Issue 01

When moisture gets inside headlights and taillights, it leads to reduced brightness, poor visibility, and warranty claims. Breather vents alone can't stop the condensation that returns with every temperature cycle.

Current approach

de:hum Carbon = (de:hum equivalent weight × volume) × 1.44 kg CO₂e/kg
※ de:hum has 3× absorption capacity, so silica gel 3g = de:hum 1g (KTR verified). The combined effect of weight reduction + 24% lower carbon intensity yields 70%+ actual reduction.

    Sustainable Packaging · Circular Economy
    PPWR is in force.
    Europe's answer is fiber.

    PPWR 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.

    Sustainable Packaging · Recyclability
    Desiccants now need
    a recyclability grade too

    de:hum Max Dry is SGS-certified 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.

    Scope 3 · ESG
    Carbon data is becoming
    a sales weapon

    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.

    EU PPWR · Regulation
    Are desiccants covered by PPWR?
    Yes — explicitly.

    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.

    Brand Reputation · Consumer
    71% want single-use plastic
    phased out

    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 · Packaging Policy
    Nestlé's phase-out list
    includes desiccants

    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.

    UK EPR · Packaging Fee
    From July, UK packaging fees
    are set by recyclability

    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 · Sustainability
    Amazon's sustainability:
    less material

    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.

    FMCG · Paper Trend
    Five FMCG giants
    dropped their plastic targets

    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.

    Material Performance · Cost
    4× the absorption of silica gel.
    Less, and lighter.

    Silica gel absorption: 20–40%. 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.
