Quick answer

To bag and board comics, choose archival supplies sized to your book, insert the board behind the back cover, slide the comic into the bag, and seal it with the flap folded over—not taped. Store them upright in a cool, dry place away from sunlight. For standard comics, a 2-mil or 4-mil bag with an acid-free board works well; for valuable issues, consider Mylar bags with full-back boards.

Why Bagging and Boarding Matters

Bagging and boarding protects comics from dust, handling, light, and moisture. Boards add rigidity, preventing spine roll and bending. Archival materials prevent acid migration that yellows pages over time. This is the first line of defense for any collection.

Choosing the Right Supplies

Bags come in materials like polypropylene, polyethylene, and Mylar. Poly bags are affordable but need replacing every few years. Mylar is inert and lasts decades. Boards should be acid-free and buffered; standard boards are thin, full-backs are thicker and offer more support. Size matters: standard comics (current) use standard bags; Golden Age and Silver Age comics need larger sizes. Always match bag and board size to your comic's dimensions.

Step-by-Step: How to Bag and Board a Comic

Work on a clean, flat surface. Wash and dry your hands to avoid oils. Handle comics by the edges. Insert the board behind the back cover, then slide both into the bag. Fold the flap over and secure with tape on the flap only—never on the bag itself. Store upright in a box or on a shelf.

Common Mistakes to Avoid

Taping the bag shut can trap moisture and damage the comic. Using too-small bags bends corners. Storing in hot attics or damp basements ruins comics. Stacking horizontally causes spine roll. Reusing old bags that have yellowed can transfer acid. Always inspect supplies before use.

Long-Term Storage Tips

Keep comics in a cool, dark, dry place. Use acid-free boxes. Avoid direct sunlight. Check periodically for pests or moisture. For high-value comics, consider professional grading and encapsulation. Replace poly bags every 3–5 years; Mylar lasts much longer.

Your Bagging and Boarding Checklist

  1. Gather supplies: Choose archival bags and boards sized to your comics. For standard comics, use standard bags and boards; for older comics, select larger sizes. Checkpoint: Ensure boards are acid-free and bags are free of PVC.
  2. Prepare your workspace: Clean a flat surface and wash your hands. Avoid eating or drinking nearby to prevent accidents. Checkpoint: Work in a well-lit area to see any existing damage.
  3. Insert the board: Slide the board behind the back cover of the comic, aligning it with the spine. The board should be flush with the top and bottom edges. Checkpoint: The board should not extend beyond the comic's edges.
  4. Slide into the bag: Carefully insert the comic and board into the bag, open end first. Avoid forcing it to prevent corner damage. Checkpoint: The comic should fit snugly without bending.
  5. Seal the bag: Fold the flap over the back and secure with a small piece of tape on the flap only. Do not tape the bag shut. Checkpoint: Tape should not touch the comic or the bag's front.
  6. Store properly: Place comics upright in an acid-free box or on a shelf. Keep them in a cool, dry, dark environment. Checkpoint: Avoid stacking comics horizontally or exposing them to sunlight.
