Durable yet flexible, these bags are puncture-resistant and semi-transparent, featuring a 0% moisture transmission rating. This ensures that rust-protected items sealed within remain free from rust and corrosion indefinitely. The bags exhibit resistance to all petroleum-based chemicals and solvents and are entirely non-biodegradable, ensuring they do not degrade even when in direct contact with soil or moisture. Their anti-static properties make them ideal as dust covers for short-term storage, whether in a vault or in the back corner of a closet.
