Comic Book Abetment Boards appear in altered thicknesses and acid-free properties. The basal purpose for application a abetment lath is to accord the comic book some stiffness, which helps accumulate the comic book pages from bending, creasing or wrinkling. When a abetment is placed in the centermost of the comic book it protects the book from crushing. The additional purpose for application a abetment lath in a backing board is its abeyant to abrogate acerbic in the comic book paper. Acid in the cardboard that the back is printed on could cause the abasement of the comic. Application an acid-free abetment in your comic book can potentially allurement and neautralize acerbic in the paper. The three types of banana abetment boards we action are: Abridgement book backings, Accepted acid-free  book backings and Archival  backings. The abridgement banana abetment should be acclimated for concise accumulator and stiffening purposes only. It does accommodate acerbic and can accord to the breakdown of the comic. People about use this lath for quick auction items. The accepted acid-free abetment actual is acid-free and can be acclimated for abiding accumulator (over 100 years). The archival banana abetment actual is acid-free and buffered with calcium carbonate, which agency that it will abide archival for 100's of years. Our abetment boards are sized to appropriately fit into our comic book bags.
