Safe Stock Book Durability.

Good morning. I have a couple of SAFE stock books, black pages and clear strips with clear interleaving. They are about 20 years old and some of the strips have become delaminated. Is this a common problem with this kind of stock book, or would I have had better luck with another brand (Lighthouse) or regular stock sheets (Vario or Hagner). Thanks.

What does "delaminated" mean (pleading utter ignorance of lamination and its uses and foibles).

Sorry, that's where the strips come unglued from the cardboard page.

I don't think its only SAFE stock books that have a problem. I have a 32 page Lindner stock book,no more than 5 years old as well as a number of Lighthouse stock books (not much older) and some of the strips have already started to separate from the pages. Could it be temperature related? Cyprus gets really hot in summer with temperatures in the 40's (Celsius}along with high humidity while the winter months are quite cold.

Actually I wrote an article about this way back in 2010 at https://www.stampcollectingblog.com...ok-pages.php (subscribers only, but there's a free trial if you want to read it).

AFAIK this affects all brands / manufacturers offering stockbooks with black pages and clear strips; only the "premium" products seem excluded (as they use slightly different kind of attachment method for the strips). Lighthouse acknowledged the problem at early 2000s: reworked their gum recipe and called the previous works as bad batch. Other makers seem to have followed with various fixups. The situation has improved a lot, but it is by no means over. Only last year a friend of mine bought a box of brand new Lighthouse stockbooks with black pages + clear strips; in less than few months the first strips peeled off

Never seen this occur with white page books having glassine strips (and I do have 150+ of them)

I have a number of Hagner pages where the clear strips become detached.

I have had a number of Lighthouse pages (black pages, clear strips) that have nearly all "fallen apart." I believe most of them to be from late seventies. I had to throw most of them away.
