Did you know that there are systems and levels when it comes to acid-free storage solutions for comic books? First of all, you should be using only acid-free sleeves, backing boards, display cases, top loaders, and storage boxes to protect comics. Also, you should nest each product into another, with proper sealing, to optimize protection.
Older comic books were made from the cheapest paper stock. Such vintage paper degrades quickly after exposure to the elements. So, you can place a comic book into a sleeve with a backing board, then into a top loader, and then into a comic book storage box. If each of those products features an acid-free coating, then the comic could last a lifetime.
