Discovered in 1933, and developed as a flexible film primarily used as a food wrap, initially marketed as "Saran Wrap." It is used as a barrier against water, oxygen and vapor. Chemically resistant to alkalies and acids, it is insoluble in oil and organic solvents, and is impervious to mold, bacteria, and insects. ]]></dc:description></metadata>
