4 mil Comic Book Bags are made of Archival Polyester (Mylar) an inert
material of the highest clarity. Mylar will not
discolour, 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. Resistance to moisture, insect attack, fungus, mold, mildew, acid,
oils, grease, and solvents. Mylar contains no
dangerous plasticizers, slip additives, surface coatings, antioxidants, acid-
hydrolysis. This bag is a semi-rigid bag and does not require the use of a
backer board. But if you do use a backer board be sure to only use certified
acid free boards.
