helix-migration Posted September 26, 2006 Report Share Posted September 26, 2006 Hi. I am new to the board and was wondering what material the PMG holders are made out of. I am thinking of getting my collection certified, but I am worried that the material might react with the paper. Is the material inert? Has anyone done research on this?

Guest Posted October 30, 2006 Report Share Posted October 30, 2006 The material that PMG uses is inert, and has been tested. The Certified Collectibles Group has been using this material for the encapsulation of comics since 2000 and have found it ideally suited for the purpose of encapsulation of notes as well.
