Comic Book Polyester (Mylar) Sleeves
MUSEUM GRADE ARCHIVAL PolyesterComic Book Sleeves These 2 and 4 mil Comic Book Sleeves are made of Archival Polyester (Mylar) an inert material of the highest clarity. We use DuPont inert Melinex® or a suitable equivalent.Polyester (Mylar) will not discolor, damage, or adhere to items placed inside it. It is a sturdy film that beautifully displays, timelessly protects, and gives extra support to fragile documents. Our polyester material has passed the Photo Activity Test (PAT).We stock 2 mil polyester sleeves with a fold-over flap. We also have two styles of 4 mil polyester sleeves. They are both made of the same archival polyester material, but they have two different flap styles:
• The Open Flap style (ROF) has to be creased to form the flap and then folded over.
• The Beaded Flap style (BF) has a third piece of polyester that is bead welded to the extended back of the sleeve, creating the flap.
