Moisture Barrier for Effervescent and Hygroscopic Supplements

Effervescent tablets and hygroscopic powders react to moisture long before the printed expiry date, so barrier is a design constraint rather than an afterthought.

Lowest-WVTR structures

• Aluminum foil laminates, including Alu-Alu systems
• Metallized barrier layers combined with a foil core
• Desiccant-containing bottle formats for multi-dose powder

Where clarity is not the priority

Opaque, foil-based packs protect hygroscopic actives better than any transparent format. Transparency is a presentation choice and should not be traded against stability.

Verify before committing

• WVTR data for the structure as supplied
• Seal integrity after forming and filling
• A line trial at production speed
