Envelopes U-style made from transparent paper

The transparent archival paper developed by KLUG-CONSERVATION differs from conventional glassine papers in that it is manufactured according to our own specifications from 100% pure virgin fibers and is free from sulfur, acids, lignin, plasticizers and metals. These archival envelopes are ideal for the preservation of photographic prints, negatives and glass plates. The opening is located on the long side.
The paper and adhesive have passed the Photographic Activity Test (PAT) in accordance with ISO 18916. Other sizes and formats are available upon request.
