| How will the capsule and inner sleeve hold up for say the next 20 years, 30 years, or 40 years? And more importantly how would that affect the books? Will it cause the pages to stick together after such a long period in the vacuum sleeve? Some books we'd like to keep for life and even pass on to our kids. Is slabbing them early a good idea? |

 Thank you sir. May I have another?

| Only way to find out for sure is to crack some of the first CGC slabs out in a few years or so (for a 20 year check). MUCH later for CBCS. PGX? I'd be concerned right now. |

| No grading company uses a vacuum seal. Whether a book is slabbed or not, the best way to preserve it is to store it properly. You want to keep them in a dark, dry, cool, climate-controlled area, and out of the light as much as possible. |

| I have heard people say you need to re-slab after 10 years. Any truth to that you guys? | ||

Quote:Originally Posted by Masochism It was seven years and that had to do with the micro chamber paper. I don't believe that really applies to CBCS graded books. I'm not sure what the cgc is currently using. I don't see it as much of a concern unless you have book in a frankenslab or a creep engine holder. |

Quote:Originally Posted by Masochism This is on CGC's FAQ page: Q: Is it necessary to get my CGC book reholdered after a certain number of years? A: No. The CGC holder is designed for long-term preservation and provides superior protection for your books. A properly handled and stored CGC-certified book can last for generations. The CGC holder is made from high-quality materials and is entirely archival-safe. The inner well that holds books, for example, is comprised of PETG, a plastic that is well known to be archival-safe and extremely clear. This PETG well is placed inside of a durable outer case that is sonically welded to ensure a secure, tamper-evident seal. For added long-term preservation, CGC inserts *MicroChamber® paper into vintage books prior to encapsulation. This MicroChamber paper helps to neutralize the natural acidity of some books by using a specialized, proprietary “zeolite” that was designed to absorb and hold the molecules known to damage archival collections. That is why MicroChamber paper is used by many of the world’s most respected museums and institutions, including the Smithsonian Institution, the Getty Conservation Institute, the Louvre, the British Museum and the Northeast Document Conservation Center. To further protect books from the natural off-gassing that releases acidic molecules over time, CGC has a secure sonic seal that is NOT airtight so that acidic molecules are not trapped inside the holder. *MicroChamber® is a registered trademark of Conservation Resources International, Inc. |

| They don't actually mention how long the slabs last in this video, but I think some of your other concerns are addressed. |

| Think about slabs like this....a study to determine plastics as they interact and are worn down by the environment suggested a plastic gallon jug, buried in the ground requires 100 years to entirely disintegrate …….so imagine how long your slab, kept safe and high and dry should hold up | ||

| i am curious also. I can tell the difference between books i left in the same boxes that were - unbagged - bagged - bagged and boarded once and left - bagged and boarded and rebagged/boarded every 10 years. basically goes from tan to white pages in order of that list. does the plastic really act the same way as the boards do in keeping the junk out of the comic? |

Quote:Originally Posted by WraithThe plastic acts even moreso than than the board as the material is more porous and absorbs acids more easily ...as the acids are pulled from the comic they either move into the backer or the bag, until one or the other or both get saturated. Ever notice how older bags get sag lines in them, then get hazy looking and eventually develop a patina coloration similar to antifreeze spilled on the ground? Those are acids that have deposited within the plastic.....sadly eventually the bag and or board can get saturated, and once they do, the acids wil return to the comic, a process called reverse migration which damages the book even worse than if they had never been removed. |
