Glassine and Barrier Paper
Glassine paper is a white, pH-neutral, translucent paper used for separating prints in storage to prevent ink from offsetting. Also known as interleaving paper, glassine paper sheets are used in bookbinding to protect artwork from acid migration and abrasion. Acid-free white tissue paper can also be used as a softer alternative to glassine. Barrier paper is another alternative for protecting archival and non-archival materials from dust and debris, and is commonly used as frame backing to give a finished look to artwork. Some varieties of barrier paper can be used for offset printing, light wet media applications, and other purposes.
