What a fiber desiccant is
A fiber desiccant is a sheet of plant fiber loaded with a hygroscopic salt, so the paper itself is the drying agent. Most desiccant paper on the market is cellulose impregnated with silica gel beads. Ours is not: the ATMOSIScience substrate is a plant-fiber matrix carrying calcium chloride, with no silica gel, no beads and no loose fill to migrate into your product.
SGS tested the bare substrate under protocol 4CE555P3 (report CQMR260700043401, 17 July 2026) and classified it as paper: fibre yield 69.78%, coarse reject 0, and a 100/100 recyclability score against every paper-packaging category in the standard. That result covers the fiber layer itself, not an assembled finished pack.
Measured performance, FPH-1 bagged fiber desiccant
- Moisture adsorption rate: over 10% of own weight at 20% RH, over 35% at 50% RH, over 70% at 90% RH
- Saturated adsorption over 100% of its own weight
- Loss on drying under 10%; substrate about 2.5 mm thick
- Sizes from 1 g to 1000 g per pouch, customizable
- Turns soft when saturated, then air dry to reuse
Fiber Desimat, the paper desiccant card
The flat format absorbs over 70% of its weight at 25°C / 90% RH, against about 30% for common silica gel. It comes in 0.5 mm and 1.0 mm thicknesses, printable on a laminated compostable film, and is free-cut to square or circular shapes.
| Spec | Size L×W×T (mm) | Mass (g) | Max adsorption (g) | Equivalent silica gel (g) |
|---|---|---|---|---|
| FF-3 | 25×12×1 | 0.15 | 0.15 | 0.5 |
| FF-6 | 30×20×1 | 0.35 | 0.3 | 1.0 |
| FF-15 | 60×25×1 | 1.0 | 0.75 | 2.5 |
Reference specifications. Custom sizes and shapes to drawing.
Why buyers switch from silica gel
- No dust, no beads, no leaks. Nothing loose to contaminate powders, optics or fabric.
- Plant-fiber substrate, industrially compostable to EN 13432 and SGS-classified as paper for recycling
- Flat formats drop into existing packaging: paper sheets, die-cut cards, tags, sachets and films
- Lower packaging-fee exposure under US state EPR programs and EU PPWR than plastic-sachet silica gel
- Backed by 70+ patents worldwide and 25+ years of R&D
Where it works
Drop it into cartons, pouches, cases or bags. In production with teams packing:
- Powders, supplements and nutraceuticals
- Electronics, IC boards, semiconductors and optical instruments
- Dried botanicals and vacuum-packed food
- Fashion, footwear, wooden toys, furniture and collectibles
- Shipping containers and export cartons
We size it with math, not a guess
How long a desiccant holds depends on how much water your packaging lets in. Send us the pack's WVTR and internal surface area and our engineers return the exact grammage using JEDEC J-STD-033B.1, plus accelerated shelf-life testing if you need the data for a QA file.
