n. ~ A supercalendared, semitransparent paper.
Glassine is often used to make envelopes to store photographic negatives. Its hygroscopic properties make it inappropriate for archival use.
†(UNESCO A/V Glossary 2001) Glassine paper is a supercalendered, smooth, dense, transparent or semi-transparent paper manufacturer primarily from wood pulps, which have been beaten to secure a high degree of hydration of the stock. It is grease resistant, and has a high resistance to the passage of air and many essential oil vapors used as food flavoring and, when waxed, lacquered, or laminated, is practically impervious to the transmission of moisture vapors.
