Most comic books have been printed on newsprint. This includes all comic books printed prior to Modern Age, as well as some Modern Age books. The reason that you will need to change the Backing Boards is that the newsprint that most comic books are printed on has been bleached with acid prior to printing, and some of the acid from the bleach remains in the paper. The Comic Book Backing Boards are coated with calcium carbonate so that they absorb the acid that migrates from the book. You will want to store them away from sunlight and in a cool dry place because sunlight, heat, and moisture can accelerate the acid migration process.
BCW Brand backing boards are solid bleached sulfate and are certified acid free by an independent testing laboratory.
The National Archives and Records Administration specified the following with regard to the long-term storage and preservation of photographic documents;
"Look for plastic enclosures made from uncoated pure polyethylene, polypropylene or polyester (also called Mylar D or Melinex 516). These are considered stable and non-damaging to photographs."
BCW Brand comic bags are made of uncoated virgin polypropylene.

Resealable Comic Book Bags
Resealable Comic Book Bags can be sealed in two ways
1. with the adhesive strip on the tab
2. with the adhesive strip on the bag
Which is better?
If the adhesive strip is on the tab it is possible to catch the comic on the adhesive strip when you slide you comic in or out of the bag, possibly damaging the comic. BCW places the adhesive strip on the bag to avoid possible damage to the comic. Just one of the many ways BCW thinks ahead for you the collector.
