Why is plant-based glycerin used in two-way humidity packs?
Plant-based glycerin is used because it can hold and release water gently, helping a two-way humidity pack correct both dryness and excess humidity instead of only doing one. Its unique value is stable, predictable moisture buffering, which helps keep texture and freshness consistent and makes humidity swings easier to prevent and spot.
