These 2 mil and 4 mil sleeves are made of Museum Grade Archival Polyester (Mylar), an inert material of the highest clarity.
• Polyester will not discolor, damage, or adhere to items placed inside it. It is a sturdy film that will give extra support to fragile documents.
• Use polyester (Mylar) to ensure your collectibles remain in excellent condition for years to come. Polyester is used worldwide in museums, libraries and archives. Our polyester material is approved by the Library of Congress for archival storage. We use DuPont inert Melinex® or a suitable equivalent.
