A thin, semitransparent, shiny paper that is strong but flexible. Glassine is made from bleached sulfite wood pulp that has been excessively beaten, hydrated then supercalendered. It is resistant to oils and greases and, when waxed or laminated, nearly impermeable to air and water. Commercially, the most common usage of glassine is for the interior packaging of breakfast cereals. It is also used for temporary interleaving, packaging, bags, envelope windows, and dust covers. Glassine has been used as a facing for the wax lining of paintings since wax will not adhere strongly to it. The translucent paper was formerly used for storage enclosures of photographic negatives, but this action has been determined inappropriate by ISO since the gelatin may attached to the glassine under humid conditions (IPI 2001). Acid-free glassine and buffered glassine tissues are available from archival suppliers.  However, even this pH neutral form is not always lignin free and may degrade with time limiting shelf life to 3-5 years ([http://www.paccin.org/content.php?78-Glassine PACCIN]).

Unbuffered See Thru, Acid-Free Glassine

Description

A thin, semitransparent, shiny paper that is strong but flexible. Glassine is made from bleached sulfite wood pulp that has been excessively beaten, hydrated then supercalendered. It is resistant to oils and greases and, when waxed or laminated, nearly impermeable to air and water. Commercially, the most common usage of glassine is for the interior packaging of breakfast cereals. Glassine has been used as a facing for the wax lining of paintings since wax will not adhere strongly to it. The translucent paper was formerly used for storage enclosures of photographic negatives, but this action has been determined inappropriate by ISO since the gelatin may attached to the glassine under humid conditions (IPI 2001). Acid-free glassine and buffered glassine tissues are available from archival suppliers. However, even this pH neutral form is not always lignin free and may degrade with time limiting shelf life to 3-5 years (PACCIN).
