Ferrous metal corrosion inhibiting sheet material

摘要

An improved sheet material for corrosion inhibition of the surfaces of packaged ferrous metal products which comprises a sheet material substrate having a vapor phase corrosion inhibitor composition applied as a printed pattern of uniformly distributed spaced - areas of predetermined size occupying about 25% of the total area of the treated sheet and consisting of a total dried weight of about 0.226 to 0.302 grams of the inhibitor composition per square foot of the treated sheet.
