Archival Polyester Envelopes

Crystal clear and heavyweight 3 mil and 4 mil Archival Polyester (Melinex or equivalent) provides excellent protection from handling as well as safe storage while transparent polyester material makes viewing possible without removing an item from the enclosure. It protects documents against outside damages ranging from fingerprints to atmospheric pollutants while being acid-free and chemically inert, which means it will not interact with the contents. Our envelopes are sealed on three sides insuring a strong seal and lasting protection. The envelopes listed under "Package of 10 with Extension Flap" feature an extension flap that protrudes an additional 0.625" beyond the open side. The 0.625" is in addition to the sizes listed. Price per package.
