Film Build Up In Uni-Safe Folders

I hope that this isn't a book made with the dreaded PVC in the plastic. I would have thought his would not be a problem with 6 onth old Unisafe books. PVC is scary stuff. I could take a picture tonight of a 1 cent coin that I just pulled from the 1973 double dollar set which included PVC. The obverse is completely covered in a gluey mixture of plastic resin and red fluff, which used to be part of a red PVC/velvet holder. Personally, I wouldn't take the chance.

There should be no PVC (Polivynilcloride) in the uni-safe blue books, from what you are describeing it sounds like you have a humidity problem.
I have seen this before, and not to put a bad spin on it it wasnt pretty. Especially if the coins are copper they will end up with a green film on them.
It doesn't matter what you do now with your folders the damage has been done the covers of the books are plastic and the inserts are attached to the plastic covers the leaching has already done its work.
I would strongly recomend you remove the coins starting with the worst looking one and lay them on a tissue to dry, then store them in 2x2 holders and pages and store them as close to the floor as possible, I have 15 volumes of coins stored this way and have had no problems in over 20 years..

The general rule of thumb for PVC (polyvinylchloride) is that if the plastic holder is soft and pliable, then chances are it has PVC. The plasticizers (typically, phthalate esters) used to soften the PVC can damage a coin's surfaces over time. The brown Coinguard albums, have the stiff to almost brittle plastic inserts, which are mylar or polyester, and are a good choice for display. Mylar also is in the windows of most cardboard 2x2 flips (most, but not all - again, push on the window with your thumb - if it breaks like a 'snap' it is safe, if you can deform the window with your thumb, without breaking, it is not safe. The mylar windows should feel slippery, not sticky...

If you like access to your coins, it sounds like all-plastic two-part holders would be best for you. You can choose flips with one pocket (for the coin) or two pockets (one for the coin and the other for a paper insert on which you can attribute and describe the coin. Unlike many other holders, safety flips let you view edge of the coin. There are two kinds of flips: 1) low-plasticizer PVC flips and 2) polyester flips. Low-plasticizer PVC flips are often mistakenly called non-PVC flips or PVC-free flips, even by some coin supply dealers, despite the fact that they're made of PVC. Low-plasticizer PVC flips are much safer than ordinary PVC flips for long-term coin storage. The good ones tend to look and feel somewhat "brittle".

As an example, this is what they look like (I just did a web image search for 'saflips'):

I have mine in uni and gardmaster there ok but have some limitations. I am looking at an altenative,I kind of like uniqe monaire system haven't tried it yet but considering it strongly. Good flexability. Similar to the 2x2 idea just better presentation.

I believe the inner flip used by ICCS are Saflips.

Thanks for the info everyone.....I do have albums for the penny and nickels, they are great for browsing, but if they are going to collect this film, I might as well buy some 2x2's and start filling them up...

Good to know. I was about to post the same question when I searched and found this post.
I recently bought books of pennies and nickels and both collections are in Uni-safe books. I liked that so I bought similar pages with coin slots for Christmas. Now I'm going to get rid of all of this stuff and switch to 2x2s or 1.5x1.5s with some good quality pocket pages instead.
