Silica Gel Product

DuPont Tyvek silica gel — the reference product of our premium line. This page shows the standard DuPont paper sachet that anchors our high-end desiccant range, available in multiple sizes and print colors to suit your packaging.

Tyvek's flash-spun polyethylene construction gives it a rare combination: paper-light, fabric-flexible, and film-strong. It is waterproof from the outside yet highly permeable to water vapor, which is exactly the physics a desiccant sachet wants. Nothing tears, nothing sheds, nothing stains.

Use this reference to compare material quality with the composite, Aihua, wax, and nonwoven versions across our silica gel series. Kam Ling supplies all of them manufacturer-direct since 1984, so you can specify different papers for different SKUs while keeping one supplier, one QC standard, and one consolidated shipment.
