    MYLAR vs POLY Comic Book Bags

    MYLAR vs POLY Comic Book Bags

    There is a lot of discussion about how to store comic books, and whether you should at all. Storage and care of your collection is entirely your choice. We at Incognito Comics believe that everyone should have the chance to look after their collection to the best standard available.

    What are comic bags?

    Comic bags protect your comics from the elements. They keep the air from reaching your books. It is the air we breath that damages, ages and decomposes your prizes collection. They stop dirt and dust from touching your collection and help prevent moisture from spoiling the paper. Paper yellows over time (due to oxygen and the danger that is air), this is why we store comics in specially produced bags with acid free boards (to prevent bending/creases/tears). There are different types of bags to store your comics in. The most common being Polypropylene and Mylar bags.

    What is the difference between poly and mylar bags?

    Polypropylene bags are common and are the cheaper option to protect your books. Standard poly bags can last between 3-8 years (NOT 50 as has been claimed). Due to its rigidity, polypropylene bags are more prone to tearing, especially at the seams. Over time you will see the bag beginning to ripple and loose its structure. Thicker poly bags may last longer. MYLAR bags are universally considered to be the BEST material to store your precious comic books and paper products in. It is what the Library of Congress in U.S. uses to store and archive historical documents.
    Mylar storage options are more expensive than poly options, however they last significantly longer, with claims you will not have to change the bag for 150 years!
    Mylar bags are made from biaxially extruded polyester film that is simultaneously stretched in two directions to give it maximum strength. It is 350 TIMES MORE RESISTANT to the diffusion of gases like oxygen, carbon dioxide, sulfur dioxide, etc. than poly bags. Mylar bags resistance to moisture, insect attack, fungus, mold, mildew, acid, oils, grease, and solvents is excellent. Mylar is the Infinity Gauntlet of storage bags.
    Poly is a good starting point, and great for short term storage solutions, where Mylar is a great investment. It all comes down to what level of care you need for your collection.

    What sizes do mylar bags come in?
    Same as comic books. Mylar comes in current, golden, silver, magazine sizes, 2mil or 4mil thickness. There is even a size specially designed for art pieces and graded comics (to fit over CGC graded comics).
