I've thrown away hundreds of flips from bleeding Chipcos and B & G chips as well over the years. No more!!! At least I don't believe so. I have been using Saflips for several years and they are wonderful at combatting bleeding and also the occasional Bud Jones chips with sticker centers that can adhere to the flip and actually tear off. Sure, many of my chips are still in older flips, which i have to transfer as I come across them, but basically every single Chipco I get now goes into a Saflip. They have no PVC (which I think is the key) and there's no oil in them either. They are a more rigid plastic than typical flips but are the same size and shape so they will fit into your pages. I hope this helps.
