moistureproof
Sealed against humidity
Moistureproof means resistant to moisture or dampness.
The term describes materials or treatments that prevent water vapor from penetrating: moistureproof packaging, moistureproof coating.
It's common in product descriptions for items that need protection from humidity—electronics, food containers, building materials.
Similar to waterproof but specifically targeting moisture rather than liquid water.
