Chunwang 2-Way Humidity Control Packs are made from natural plant fibers and polymer materials. They are widely applicable, non-toxic, odorless, safe, eco-friendly, highly precise in humidity control, and easy to use.
Why Choose 2-Way Humidity Control Packs?
Every product has an ideal storage humidity range. For example, capsules are best stored at 30%–40% RH—too low and they may become brittle; too high and they can stick together. Our humidity control packs accurately maintain your desired humidity level by releasing moisture when it’s too dry or absorbing excess moisture when it’s too humid. This ensures your products remain stable and well-protected.
Key Features of Our Humidity Control Packs:
1) Broad Applicability – Capable of achieving and maintaining any target humidity level between 30% and 90%.
2) Non-Toxic & Odorless – Safe and free of odors, making them suitable for pharmaceuticals and other hygiene-sensitive applications.
3) Eco-Friendly & Safe – Made from natural plant fibers and polymer materials for reliable and green humidity control.
4) High Precision – Offers humidity control within ±3% deviation, achieving a 40% improvement over traditional silica gel desiccants.
5) Superior Performance – Delivers excellent moisture absorption and release under varying conditions.
6) Easy to Use – Compact sheet design saves space, prevents leakage, and ensures clean, hassle-free operation.
Crafted from natural plant fibers and polymer materials, it is non-toxic, safe, and environmentally friendly. The sheet is packaged in durable, tear-resistant DULAI paper, which offers excellent breathability.
The greater the humidity control within the target range, the better the product performance. The table below compares the humidity control capabilities of various foreign silicone-based brands with Chunwang HumiWise fiber-based humidity control packs across different humidity ranges.

| 70%-80% | 2% | 13% | 18% |
| 80%-90% | 2% | 7% | 18% |
Regardless of external humidity fluctuations, Chunwang HumiWise Humidity Control Sheets accurately maintain stable humidity levels within the packaging environment (below are the measured data for RH50% specification sheets in storage boxes).
Before Use: The humidity inside the packaging fluctuates dramatically with external temperature changes.
After Use: The humidity inside the packaging remains very stable, unaffected by external temperature variations.
Wide Applications: Suitable for products with specific humidity requirements, including capsules, traditional Chinese medicine, ginseng, tobacco, cigars, fabrics, antiques, jade, artworks, specimens, and musical instruments (with recommended humidity levels for some products).
