Applications
Where BRANOdry Protects Your Products
Moisture is one of the most common causes of quality loss during storage and transport. BRANOdry provides reliable protection – across all industries.
BRANOdry absorbs moisture from the air and protects packaged goods from moisture-related corrosion, functional failure, and quality loss – both during storage and throughout the supply chain.
Thanks to its corrosion-neutral properties, BRANOdry is ideal for metal parts, machine components, spare parts, and technical assemblies – even on long transport routes or under fluctuating climate conditions.
Combined with moisture-resistant or heat-sealed packaging, BRANOdry creates a controlled microclimate – ensuring permanently stable conditions inside the package.
Technical products and sensitive components react to changes in humidity. BRANOdry helps stabilise ambient conditions during storage and shipping.
As a clay desiccant conforming to DIN 55473, BRANOdry delivers standardised desiccant units (DU) with reproducible moisture absorption – wherever defined standards are required.
The Product
BRANOdry – Bentonite-Based
Desiccant Bags
BRANOdry is a high-performance desiccant based on natural bentonite – specifically developed for reliable moisture protection in industrial packaging. The desiccant bags are made from tear-resistant, dust-tight non-woven material and protect sensitive products from moisture-related corrosion and quality loss – whether during storage or international transport.
As a natural raw material, bentonite is completely corrosion-neutral and releases no harmful substances into the packaging environment – a decisive advantage for sensitive industrial applications. Unlike certain synthetic alternatives, BRANOdry does not release absorbed moisture back into the surrounding environment.
BRANOdry meets the requirements of DIN 55473 and achieves an adsorption capacity of at least 6 g of water per DIN unit at 23 °C / 40% relative humidity.

Material Comparison
Bentonite Instead of Silica Gel
Silica gel dominates the desiccant market – but for many industrial applications, bentonite is the better choice. BRANOdry deliberately uses this natural raw material.
Bentonite is corrosion-neutral and suitable for use with sensitive metal and electronic components. Unlike silica gel, BRANOdry does not release absorbed moisture back into the environment, even under heat exposure.
In addition, bentonite is safe to dispose of – an increasingly important criterion for sustainability-focused companies in the B2B sector.
| Criterion | BRANOdry (Bentonite) | Silica Gel |

| Corrosion-neutral | ✓ Yes | ⚠ Conditional |
| Natural raw material | ✓ Yes | ✗ Synthetic |
| Moisture re-release | ✓ No re-release into environment | ⚠ Possible |
| No harmful substances | ✓ Mineral raw material | ⚠ Depends on type |
| Disposal | ✓ Safe | ⚠ Restricted |
| DIN 55473 compliant | ✓ Yes | ✓ Yes |

FAQ
Frequently Asked Questions about BRANOdry
Everything you need to know about desiccants, DIN 55473, and our product – answered concisely.
A desiccant bag contains an absorbent material – such as bentonite or silica gel – that absorbs moisture from the surrounding air. It is placed inside packaging to protect goods from corrosion, mould, and quality loss during storage and transport.
Desiccants work through adsorption: the material binds water molecules from the air onto its surface, reducing the relative humidity inside the packaging. Adsorption capacity varies depending on the material and DIN unit.
DIN 55473 is the international standard for desiccants in the packaging industry. It defines desiccant units (DU), fill weights, and minimum adsorption capacities – ensuring comparable, reproducible quality.
BRANOdry is based exclusively on natural bentonite – a corrosion-neutral mineral raw material with no chemical additives. Unlike synthetic alternatives, BRANOdry does not release absorbed moisture back into the environment and is safe to dispose of.
