Once Sealed It's Impervious To Moisture
Tough but flexible; these bags are puncture resistant, semi-transparent and have a 0% moisture transmission rating, so rust-protected items sealed inside will remain rust and corrosion free indefinitely. Resistant to all petroleum based chemicals and solvents and completely non-biodegradable, so they will never break down even in full contact with soil or moisture. Anti-static properties make them a perfect dust cover for short term storage in a vault, or even in the back corner of a closet.
