Abstract
A packaging film for use in inhibiting corrosion in packaged goods includes a polymeric substrate resin, between about 1 and 2% by weight of one or more corrosion inhibiting materials, and between about 2 and 10% by weight of nano-clay particles. The packaging film may be formed as a multiple layer co-extruded film, wherein a first polymeric layer is disposed between a second polymeric layer including nano-clay particles, and a third polymeric layer including one or more corrosion inhibitor materials.
