One patented composite: plant fiber plus calcium chloride. Over 100% of its own weight in water at 90% RH, with no silica gel and no dust.
Our fiber desiccant is designed for brands and manufacturers that need reliable moisture control without bulky sachets, loose silica gel, or unnecessary plastic. Each format can be customized based on product sensitivity, target absorption, machine compatibility, and packaging space.
Patented lignocellulose fiber with calcium chloride. Sachets, paper desiccant cards and die-cut discs from one platform.

Custom-printed sachets and discs carry your brand
0.7 mm ultra-thin or 1 mm maximum capacity, your call.
2-3× silica-gel capacity. No dust, no beads. Industrially compostable.

Same protection, less mass: a 2 g fiber desiccant card absorbs as much moisture as a 5 g silica gel sachet.
Why fiber outperforms purely physical adsorbents.
Porous lignocellulose draws moisture into micro-channels by capillary action, faster uptake than dense clay.
Calcium chloride locked in the fiber matrix hydrogen-bonds water, high capacity with no brine leak, dust, or corrosion.

Yes, usually with far less mass. At RH 90% / 25°C, 1 kg of fiber absorbs ~1.5 L of water versus ~0.3 L for silica gel. Most carton applications need one-third to one-fifth of the silica-gel mass.
Yes. Fiber Desiccant Card is our paper desiccant: a thin, paper-like card made from patented plant fiber with calcium chloride locked in the fiber matrix, laminated with a printable compostable film. It absorbs over 70% of its own weight at 25°C / RH 90%, comes in 0.7–1.0 mm thicknesses, and is die-cut to fit bottle caps, blister packs, pouches and garment tags.
Every quote ships with the document pack: MSDS, SGS recyclability report CQMR260700043401, ISO 14067 product carbon footprint, RoHS and heavy-metal results (lead and arsenic at or below 1 µg/ml, E. coli not detected), plus the EN 13432 compostability test basis. Qualify the material against your own food-contact or pharmacopoeia requirements using that pack. Standard desiccant handling warnings apply: not intended to be ingested.
Clay products cap out around 25–35% absorption by weight, similar to silica gel. The fiber active delivers over 100% (FPH-1) or over 70% (Fiber Desiccant Card, our paper desiccant). The compostable-bag story is comparable; the performance story is materially different.
Yes: SGS Compostable (EN 13432), ISO 14067 product carbon footprint, and SGS Anti-mould. Full certificates are available on request.
