12" x 18" Zerust® VCI Anti-Rust Zipper Poly Bag - Yellow Tinted (4 mil)

Rust inhibiting film offers corrosion protection for ferrous metals such as iron, cast iron, and steel. Emits odorless, invisible, and non-toxic vapors that prevent rusting. Does not contain amines, phosphates, or amines in combination with nitrites and nitrates. Zipper bags have a reinforced spot-welded zipper that creates strong stress point support, but slightly narrows the bag opening. Environmentally safe.
