About Desiccants
Silica Gel & Molecular Sieve Desiccants for Moisture Control in South Africa
Silica gel desiccants are among the most widely used and reliable solutions for humidity control in sealed packaging environments. Designed to actively adsorb moisture from surrounding air, silica gel helps protect products from humidity-related damage during storage, transportation, and export.
In high-humidity environments – particularly in coastal regions of South Africa such as Durban, Cape Town, and Gqeberha – excess moisture can lead to mould growth, corrosion, packaging failure, and product degradation.
Silica gel provides a stable, cost-effective, chemically inert moisture-control solution suitable for food, pharmaceutical, industrial, and export packaging applications.
Desiccant Types
Sil-Pac supplies a range of desiccant technologies used to control moisture and humidity levels across industrial, pharmaceutical, warehousing, and export packaging environments.
These desiccant technologies help manage moisture exposure during storage, shipping, warehousing, and long-distance transportation where humidity can cause condensation, corrosion, mold growth, and product damage.
Our desiccant range includes:
Silica gel desiccants
Molecular sieve desiccants
Activated alumina desiccants
Container desiccants
Desiccant SOLUTIONS






Silica Gel Desiccants
Silica gel works through adsorption, where water vapor adheres to the surface of microscopic pores within the silica beads without changing the structure of the desiccant itself.
This makes silica gel non-toxic, odorless, chemically stable, and suitable for a wide range of packaging and industrial moisture-control applications.
Available Formats
Sil-Pac supplies silica gel desiccants in multiple formats to suit different packaging and industrial moisture-control requirements.
Available options include:
- 0.5g, 2g, 5g, 10g, 50g, 100g, and 150g silica gel sachets

Molecular sieve desiccants
For applications requiring extremely low humidity levels and highly precise drying performance, molecular sieve desiccants offer superior moisture adsorption compared to conventional silica gel.
These desiccants are widely used in pharmaceutical, petrochemical, refrigeration, gas drying, and industrial processing applications where strict moisture-control standards are required.
