Wisesorb 5g Desiccant Packets Bulk – Molecular Sieve Sachets for Large-Format & Long-Term Use

5g Desiccant Packets Bulk – Molecular Sieve Sachets for Large-Format & Long-Term Use When the package is big, the storage period is long, or the environment is unforgiving, you need a desiccant with real capacity behind it. The 5g molecular sieve sachet is our highest-capacity standard size — built for applications where running out of desiccant capacity mid-shelf-life simply isn’t an option.

But for applications that demand humidity below 20% RH — or where the desiccant needs to keep performing across wide temperature swings, extended storage periods, or harsh environments — molecular sieve 4A is the professional standard. It adsorbs faster, holds more at low humidity, and doesn’t give out when conditions get tough. Product Specs Sachet weight: 5g Sorbent: Molecular Sieve 4A (0.4nm pore diameter) Absorption capacity: >17% of its weight at 25°C / RH 20% Packaging: Breathable nonwoven, dust-free, no binders or solvents Seal type: Melt-seal edges – packaging-line compatible Back window: Transparent – visually confirm sorbent fill Operating temp: -20°C to high-temp environments Who Uses the 5g Sachet? 🩺 Oversized Medical Device & Implant Packaging Large orthopedic implant sets, spinal surgery kits, and multi-component sterile procedure packs require desiccant capacity that matches their internal volume. A 5g sachet handles the moisture load in oversized sealed trays and rigid packaging formats — keeping sterile conditions intact from your production floor to the point of use. 🏭 Heavy Industrial & Outdoor Equipment Enclosures Large electrical enclosures, transformer housings, and outdoor control cabinets in North American industrial and utility environments face extreme seasonal humidity variation. A 5g sachet provides the sustained moisture control needed to protect high-value equipment over long service intervals — from harsh Canadian winters to humid Gulf Coast summers. 📦 Long-Term Transit Cases & Military Packaging Defense and aerospace contractors packaging optics, electronics, and precision instruments for long-term storage or overseas deployment need desiccants that won’t saturate before the container is opened. The 5g sachet delivers the capacity required for extended sealed storage without compromise. 🔬 Biotech & Vaccine Cold-Chain Packaging High-value biologics, lyophilized vaccines, and enzyme reagents shipped through North American cold-chain networks are exposed to significant humidity variation at every handoff. A 5g sachet inside each insulated shipping container provides the desiccant reserve needed to protect product integrity across the full distribution journey. 📚 High-Value Archival & Preservation Storage Institutions protecting irreplaceable materials — film archives, rare document collections, optical media libraries — rely on the 5g sachet for sealed containers where desiccant replacement is impractical. The high capacity means longer intervals between maintenance checks and more reliable long-term protection. Frequently Asked Questions Do you ship to Canada? Yes. We ship from our US warehouse to both the continental US and Canada. Canadian customers get significantly faster delivery compared to sourcing from overseas. When does it make sense to use 5g instead of a smaller sachet? The 5g sachet is the right choice when your package has a large internal volume, a long shelf life or storage period, or will be exposed to demanding environmental conditions. If you’ve had smaller sachets saturate before the product reaches its end user, the 5g eliminates that problem. How fast does it ship? Most orders ship within 1–2 business days from our US warehouse. In-stock inventory is ready to go — no waiting on overseas production or freight. What’s the minimum order? 100 pcs at $25.00 — suitable for product evaluation or small production runs. Larger quantities bring the per-unit cost down to $0.092/pc at 3,000 pcs. Can I order more than 3,000 pcs? Yes. Contact us with your required quantity and we’ll reply with a confirmed delivery date based on your order size. Can these run on automated packaging lines? Yes. Melt-seal edges and consistent sachet dimensions make these compatible with standard high-speed packaging equipment used across North American production facilities.
