Why Industry Leaders Choose Our Desiccant Sachets
In a complex global supply chain, you need a partner who understands the stakes. Here is how we help you overcome your critical shipping and packaging challenges:
1. Eliminate the Risk of “Container Rain”
You shouldn’t have to worry about your cargo’s safety on the high seas. You know the damage that temperature fluctuations can cause—condensation inside shipping containers that leads to moldy textiles and corroded metal parts.
We equip you with high-performance Calcium Chloride desiccant packs. Designed to aggressively absorb up to 300% of their own weight in moisture, they lock humidity inside a leak-proof gel. We keep dew points well below danger levels for over 90 days, ensuring your goods arrive in the exact condition they left your warehouse.
2. Navigate Global Regulations with Confidence
Expanding into EU or US markets shouldn’t mean drowning in red tape. Strict adherence to chemical safety standards (like REACH and RoHS) and plastic bans can complicate your export process.
We ensure your compliance is seamless. We offer you plastic-free, biodegradable mineral desiccants and formulations completely free of DMF. With our certified solutions, you can clear customs without delay, confident that your packaging meets the highest global environmental and safety standards.
3. Maximize Protection in Minimal Space
Don’t let bulky protection compromise your sleek product design. Whether you are packaging compact electronics or pharmaceutical bottles, you have zero tolerance for wasted space.
We provide protection that fits your constraints. Our Fiber Desiccants and compact Molecular Sieve sachets deliver maximum adsorption density in ultra-thin profiles. We can even provide customized shapes (such as 1/6 Unit sizes), giving you superior moisture control that integrates invisible into your packaging.

Desiccant Packs: Frequently Asked Questions
Silica Gel is a physical adsorbent ideal for small packaging and electronics, offering rapid moisture uptake (approx. 30% capacity). Calcium Chloride is a chemical absorbent that offers superior capacity (up to 300%) and is ideal for long-duration storage or shipping containers where high humidity is a constant threat.
Yes, we offer specific Food Grade desiccant packets and Oxygen Absorbers that are safe for direct contact. Our products are DMF-free and comply with REACH and RoHS standards. We also use packaging materials that prevent any leakage or contamination.
Yes. We offer OEM/ODM services. We can customize the weight (e.g., 1g, 5g, 50g, 1kg), the sachet dimensions, and the packaging material (Tyvek, non-woven, clear film). We can also print your brand logo and warning text in multiple languages.
Dosage depends on the volume of the packaging, the duration of storage, and the expected ambient humidity. As a general rule for standard silica gel, we recommend specific gram weights per cubic foot. However, for our high-absorption CaCl2 packs, you can often use significantly less product to achieve better results. Contact our engineering team for a free calculation.
No. All our products are strictly DMF-Free. We ensure our products meet the strict import regulations of the European Union and the United States regarding hazardous anti-mold chemicals.
