Micro-Pak Dri Clay® Kraft
The Most Sustainable & Effective Desiccant for Moisture Control
Micro-Pak Dri Clay® Kraft is a certified plastic-free desiccant made from natural bentonite clay that is packaged in biodegradable FSC (Forest Stewardship Council) Kraft paper. Dri Clay® outperforms silica gel and calcium chloride desiccants in moisture reduction, and safely protects a wide range of goods from mold and moisture damage. Dri Clay® is the first and only certified plastic-free desiccant.
- Eco-Friendly: Certified plastic-free. Natural and biodegradable
- Effective: Outperforms silica gel and calcium chloride in moisture reduction
- Safe: Non-toxic and free of harmful chemicals. No leakage and non-corrosive.
Product Details
Maximum Protection: Moisture is the enemy of quality—inviting mold, mildew, rust, and corrosion. Micro-Pak Dri Clay® is the most sustainable and effective desiccant on the market, defending your goods from moisture and extending shelf life. Micro-Pak Dri Clay® absorbs moisture better than silica gel or calcium chloride, offering the best possible protection to any product—especially those sensitive to moisture like textiles, home furnishings, wood, paper, electronic appliances, food, supplements, medical devices, metal components and many others.
A Safe and Natural Desiccant: Bentonite clay is a naturally occurring mineral without any chemical additives that is known for its excellent moisture-absorbing properties. It excels at reducing moisture within packages to lower levels than silica gel, calcium chloride and other synthetic desiccants.
Dri Clay® meets US (FDA, Food and Drug Administration) and EU (BRCGS) requirements for food and drug contact, and is an excellent alternative to silica gel for nutraceutical and food applications. It is exempt from REACH registration but it nevertheless passes all tests for REACH Substances of Very High Concern (SVHCs) among other restricted substance tests.
Unlike other desiccants, Dri Clay® poses no leakage risks because the clay remains dry even at full adsorption capacity. It also protects metal parts with no risk of corrosion, unlike highly corrosive calcium chloride desiccants.
Economical and Easy to Use: Dri Clay® is available in six sizes to fit your packaging needs, allowing you to eliminate moisture effectively and economically. Use it on its own or in conjunction with Micro-Pak® Stickers and Micro-Pak® PE Sheets for a comprehensive anti-mold and anti-moisture solution.

Choose Micro-Pak Dri Clay® instead of silica gel desiccants
A more sustainable desiccant: Manufacturing with naturally-occurring, 100% natural bentonite clay requires no water or chemicals, and little energy. This production process is far more sustainable than the energy-intensive production of synthetic silica gel, which requires chemical feedstocks and significant fresh water, while also producing pollutants, effluents, and discharges. Most silica gel is packaged in plastic whereas Micro-Pak Dri Clay® is the first and only certified plastic-free desiccant.
Superior performance and handling: Micro-Pak Dri Clay® outperforms silica gel, reducing humidity faster and to lower levels in most packaging conditions. It is also easier to handle so you run less risk of the desiccant reaching saturation in your factory before it’s packed with your products. Furthermore, there is significant variation in the quality of silica gels and many commonly found silica gels have no capacity to absorb moisture.
Better regulatory compliance: Micro-Pak Dri Clay® is 100% natural, DMF Free, exempt from REACH registration, and compliant with other international regulations. Silica gel requires REACH registration and is far riskier, with DMF (a substance banned in Europe) and cobalt chloride (a possible carcinogen) having been detected in it.
Choose Micro-Pak Dri Clay® instead of calcium chloride desiccants
A more sustainable desiccant: Calcium chloride desiccants turn into a corrosive liquid gel when they absorb moisture and to prevent leakage they are packaged in two layers of plastic, comprising an inner plastic pouch with an outer non-woven sleeve. Micro-Pak Dri Clay® is the first and only certified plastic-free desiccant, and the Kraft paper packaging is also biodegradable. When disposed in landfill, the clay is returned to the earth in its original form while the Kraft paper will biodegrade.
Leakage-free and non-corrosive: Micro-Pak Dri Clay® remains dry at all times, even at full water vapor capacity, so you never have to worry about leakage. But when calcium chloride absorbs moisture, it becomes liquid which poses high risk for leaking and damaging products. Furthermore, calcium chloride is highly corrosive especially to metal parts, whereas Micro-Pak Dri Clay® carried zero corrosion ris. Overall, Micro-Pak Dri Clay® is a much safer desiccant option.
Smart for packaging: Because Micro-Pak Dri Clay® adsorbs at a consistent rate, through a wide range of humidity levels, it lowers humidity inside packaging faster and to lower levels than calcium chloride—reducing the risk of mold, mildew, and other moisture-related problems. Calcium chloride only absorbs moisture very quickly in environments with sustained levels of high humidity, making it an effective ingredient for shipping container desiccants—but a poor choice for packaging.
