Polyester(Mylar)Sheets

Use Polyester (PET) Sheets for matboard windows, encapsulating irregular sizes, interleaving or any archival application. Archival polyester will not discolor, damage, or adhere to items placed in it or next to it. This polyester material is approved by the Library of Congress for safe indefinite-term storage. We use DuPont inert Melinex® or a suitable equivalent.

For safe encapsulation, use acid-free double-sided transparent tape.
