Polyester Sleeves

Our Polyester (Mylar) Folder Sleeves are made from crystal-clear, 4 mil archival polyester, approved by the Library of Congress for indefinite archival storage. We use Dupont inert Melinex or a suitable equivalent. Our polyester has passed the Photo Activity Test (P.A.T.) which means that items put in the sleeves with not react with polyester material. Polyester is a sturdy, crystal-clear material with a glass-like surface and archival properties that are approved by museums for indefinite storage (hundreds of years).
We stock four categories of 'Folder' Sleeves:
• First Day Covers
• Negative Strips
• Movie Posters
• Digital Photo
These sleeves are sealed on one long side, which allows for easy document insertion and retrieval. Once inserted sleeved contents remain in place due to the static-cling nature of polyester material.
