MOISTURE ABSORBERS
Absorbers | moisture absorbers
::Protect your products from humid environments by different types of moisture absorbers: Silica Gel, Desiccant Clay (Activated Bentonite), Molecular Sieve or home desiccant (Sanidry).
Silica Gel is a humidity absorber, dry agent, produced with amorphous silica and comes in the form of a semi-transparent hard granule. As part of moisture absorbers, desiccant silica gel have a great absorption capacity and this varies depending on the environmental conditions.
Desiccant clay or bentonite is a natural desiccant that is activated by specific drying conditions. The desiccant has a great ability to absorb moisture when it is activated, varying according to environmental conditions like Silica Gel does.
The molecular sieve is obtained synthetically from zeolite compounds. It is not just a traditional desiccant or moisture absorbent but it has other types of applications as a filter of different chemical substances.
The home moisture desiccant Sanidry is a dry agent specially designed for moisture problems in closed habitable places: houses, basements, garages, caravans, cars, boats, cabinets, etc. Sanidry Tray is placed in places with little ventilation in which there is usually humidity due to some filtration problem, condensation or any other reason that is generating humidity.

Silica Gel
Desiccant silica gel improves the protection of the products against possible damages due to humidity, decreasing the dew point in the packaging during transport or storage. Thanks to silica gel packets retains its quality, stability and properties of use that the humidity could modify, vary or destroy. The supply is made both in bulk and in desiccant bags or practical bags. It is also possible to supply tissue that meets the FDA. Thanks to its small size, silica gel packets occupies very little space inside the packaging.
Desiccant clay
The clays and their tissues are selected to guarantee the quality of their products in terms of resistance and high levels of absorption. This desiccant can be supplied in desiccant bags, desiccant packs, chains and panels with standard fabric or in compliance with the FDA. On request it is also possible to include a humidity indicator on the packaging to know when to replace the desiccant clay.
Eco-sustainable desiccant clay
Green desiccant for absorption are an effective and safe solution to avoid damage caused by variations in humidity and temperature during the transport and storage of your products. This eco-sustainable desiccant is produced with natural raw materials and a biodegradable nonwoven fabric, they are perfect for protecting and reducing the level of humidity in the packaging while respecting the environment.
Antistatic desiccant bag
Anti-static desiccant bag made of natural clay, moisture absorber with anti-static non-woven fabric for electronic components.
Maritime container desiccant
Desiccant trays and desiccant hook bags to reduce the relative humidity in sea containers, keeping it below the dew point. These desiccants are composed of calcium chloride and other additives.
Automotive desiccant bags
We offer desiccant bags for automotive refrigeration and for provide expert protection against moisture problems associated with air conditioning systems, electric vehicles, and alternative engines.
Molecular sieve
These desiccants are ideal when there is a need to absorb moisture very quickly. It is because they absorb molecules based on the principle of polarity difference due to electrostatic attraction as they have a uniform porous structure that allows the separation of the molecules by size. Molecular sieve is a dry agent supplied in bags or bags for disposal in packaging.
Sanidry. Desiccant tray. Dehumidifier
Sanidry tray moisture packets to remove humidity in your home, boats, caravans or cars with Sanidry trays in a comfortable and practical way. This dehumidifier dry desiccant can be used in a wide variety of closed places with little ventilation.

FAQs
Moisture absorbers: technical guide and answers to frequently asked questions
What problems can moisture cause in products and packaging?
Moisture is a silent threat to any sensitive product. It can cause corrosion in metal components, mould growth, condensation inside packaging, material deformation and loss of efficacy in pharmaceutical or food products. Controlling this factor is essential to preserve the quality, appearance and functionality of the product, especially during transport and storage.

How do I choose the most suitable moisture absorber for my application?
The right choice depends on the volume of the space to be protected, the type of packaging, the expected humidity level, the duration of storage, and the sensitivity of the product. For example, a pharmaceutical product in blister packaging requires a small, safe desiccant, while an international shipment requires high-performance solutions. At Sercalia, we help you find the ideal solution for your specific application.
What is the difference between the various types of desiccant bags?
The main difference lies in the absorbent material:
- Silica gel: good capacity in stable environments.
- Natural bentonite: a natural and economical option.
- Molecular sieve: high performance at low humidity levels.
- Eco-sustainable: ideal for sustainable projects.
Each has particular advantages depending on the environment, the type of product, and the applicable regulations.
What solutions does Sercalia offer for large volumes or long-distance transport?
For shipping containers or industrial warehouses, Sercalia offers large-surface absorbent blankets, hanging desiccants for containers, and industrial trays designed to operate for long periods. These solutions are key to preventing dew point and other effects of severe condensation.
Can I combine moisture absorbers with other protection systems?
Yes. It is common to combine moisture absorbers with oxygen absorbers, modified atmosphere packaging (MAP), or thermal stabilisers for complete protection. In highly sensitive products, these combinations significantly increase shelf life and reduce the risk of deterioration.
In which sectors is the use of moisture absorbers recommended?
Moisture absorbers are essential in:
- Food: nuts, baked goods, food supplements.
- Pharmacy and laboratory: capsules, vials, sensitive formulas and fine chemicals.
- Electronics: circuits, sensors, precision optics.
- Automotive and aeronautics: metal parts, engines, technical packaging.
- Art and heritage conservation: display cases, archives, libraries.
Are moisture absorbers safe for food or pharmaceutical use?
Most of the products offered by Sercalia are manufactured with non-toxic materials and are suitable for indirect contact with food or medicines. They comply with international regulations (FDA, USP, etc.) and are available with technical data sheets and certifications on request.
How long does a moisture absorber remain effective?
The duration varies depending on the type of material, volume of air to be protected, temperature, and sealing of the container. Under ideal conditions, it can remain active for months. For critical applications, we recommend using models with a saturation indicator that allows you to visually check when the desiccant needs to be replaced.
