Introduction:

The Chunwang 2-Way Humidity Control Packs are made from natural plant fibers and polymer materials. They are characterized by their wide applicability, non-toxic and odorless nature, safety and environmental friendliness, high humidity control precision, excellent performance, and ease of use.

Why Use 2-Way Humidity Control Packs ?

Every product has an optimal storage humidity level (for example, capsules should be stored at 30% to 40% humidity; too dry can cause them to crack, while too humid can lead to sticking). 2-Way Humidity Control Packs can accurately maintain the storage humidity within a specific range (releasing moisture when it’s low and absorbing moisture when it’s high), ensuring better quality preservation of the stored products.

Features of 2-Way Humidity Control Packs:

1. Wide Applicability: Capable of adjusting and maintaining humidity levels anywhere between 30% and 90%.
2. Non-toxic and Odorless: Safe for use in humidity control of medicinal materials.
3. Environmentally Friendly: Made from natural plant fibers and polymers, ensuring safety and environmental sustainability.
4. High Precision: Humidity control precision of ±3%, outperforming traditional silica gel humidity packs by 40%.
5. Excellent Performance: Outstanding effectiveness in both moisture absorption and release.
6. Convenient to Use: Sheet form for easy handling, space-saving, and no risk of particle leakage.

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.

RH Range	German Brand P (Silica Gel Type)	Japanese Brand A (Silica Gel Type)	Chunwang HumiWise (Fiber-Based)
30%-40%	6%	6%	10%
40%-50%	8%	4%	15%
50%-60%	8%	9%	16%
60%-70%	6%	18%	20%
70%-80%	2%	13%	18%
80%-90%	2%	7%	18%

Made from natural plant fibers and polymer materials, the product is non-toxic, harmless, and environmentally friendly. It is packaged in durable and flexible DuPont paper, which offers excellent breathability.

Raw material & packaging material

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).
