Humidity Control Liner | D52 | 10,000 units

Humidity-Control Jar Liner — Two-Way Humidity, Plant-Based, Heat-Seal or Friction-Fit, Aroma-Safe

Built-In Humidity Control Liner for Jars

Our Humidity-Control Liner with fiber integrates directly into the lid to regulate humidity from the inside — no loose packets, no salt, no liquid.
Once the jar is sealed, it gets to work: absorbing excess moisture when it’s too humid and releasing moisture when it’s too dry.

That means your contents stay at 62% RH — right where they should be.

Why It Works

• 2-way humidity control built into the lid

• ±2% RH accuracy, stable in any climate

• Zero risk of leaks or corrosion

• Made from bamboo and wood fiber — compostable and safe for sensitive goods

• Keeps natural aroma and freshness intact for extended shelf life

Whether you’re storing botanical materials, dried herbs, or other moisture-sensitive goods, this liner creates a sealed microclimate that keeps them consistently fresh and protected.
