This high-performance desiccant substrate rapidly absorbs moisture—up to 300% of its weight—to reliably protect sensitive products in demanding environments. Its micro-porous structure blocks desiccant leakage (≥99.9%) while permitting vapor transmission, ensuring contamination-free operation. With high tear strength (≥15 N/25mm) and abrasion resistance, it withstands high-speed packaging and extended storage. Compatible with all major desiccants, it offers customizable humidity solutions for electronics, pharmaceuticals, food, precision instruments, and automated packaging systems.

Rapidly absorbs water vapor (up to 300% of its weight in saturated environments) to maintain a dry atmosphere, preventing corrosion, mold, and performance degradation in electronics, pharmaceuticals, and food products.
The micro-porous structure (pore size: 0.1–5 μm) allows vapor transmission while blocking desiccant particle leakage (retention rate ≥ 99.9%), safeguarding precision components from contamination.
Exhibits excellent tear strength (≥ 15 N/25mm in MD/CD) and abrasion resistance, withstanding high-speed packaging processes and long-term storage without structural failure.
Works seamlessly with silica gel, molecular sieves, and montmorillonite, enabling customized moisture-control solutions for diverse humidity challenges.
1. Electronics & Component Packaging: Protects sensitive devices from moisture during storage and shipping, preventing corrosion and failure while ensuring clean, particle-free interiors.
2. Pharmaceutical & Medical Product Preservation: Maintains dry conditions in medicine packaging, extending shelf life and stabilizing efficacy by controlling humidity and blocking contaminants.
3. Food & Nutraceutical Storage: Reduces moisture in dried food, supplements, and perishable items to prevent clumping, mold, and quality loss.
4. Precision Instrument & Machinery Protection: Used in packaging or casing of optical, mechanical, and automotive components to avoid humidity-induced damage or operational issues.
5. Custom Desiccant Integration & High-Speed Packaging: Compatible with various desiccants; ideal for automated packaging lines requiring durable, high-strength, and leak-proof moisture control materials.
