Desiccant stopper for tablet tubes

Manufacturers of pharmaceuticals and foodstuffs must reliably protect sensitive products from moisture. Particularly hygroscopic products such as effervescent or chewable tablets react strongly to humidity – they can clump, change their consistency or lose effectiveness. To ensure product quality, desiccant stoppers are used that seal tubes airtight and bind moisture with silica gel.

Challenge:
Moisture protection for sensitive contents

In pharmaceutical and food production, moisture influences must be consistently avoided to ensure the stability of the ingredients. Classic packaging solutions reach their limits here, as they do not offer active moisture control. Particularly with automated filling processes or long transport routes, an integrated, safe moisture protection is therefore required.

Solution: Silica gel granules or CapDryy® desiccant stoppers

ThoMar supplies high-purity, microporous silica gel to an international packaging manufacturer, who integrates it into components of tube packaging. The material keeps the humidity inside the packaging permanently low and reliably protects the product.
Alternatively, ThoMar offers CapDryy® – an integrated desiccant capsule that is inserted directly into plastic closures. It contains pharmaceutically suitable silica gel, is designed for automated production lines and meets FDA requirements.

Result: Maximum product safety and stable storage conditions

Through the targeted use of silica gel granules or CapDryy® closures, the quality of sensitive products is permanently maintained. Manufacturers benefit from a controlled moisture level in the packaging, longer shelf life and a process-safe, regulatory-compliant solution for demanding applications.
