Microchamber Paper / Boards / Boxes

^{Microchamber paper with honeycomb watermark}

MicroChamber Paper is a thin sheet of paper infused with SPZ zeolite molecules which have the ability to absorb and neutralize acids and pollutants such as those released by the collection itself. They are an essential part of animation art preservation. 

Collectors should slip a piece of microchamber paper in front or behind their cels to absorb any off gassed fumes. If placing microchamber behind a cel please consider placing a sheet of clear plastic between the cel paint and microchamber paper to prevent the paint from sticking to the microchamber paper.

Note: When purchasing microchamber paper it will not always have the honeycomb watermark. Due to manufacturer issues they no longer produce microchamber paper with the watermark. 

Other storage products using Microchamber/Zeolite technology include art backing boards and storage boxes. Please be aware there are also buffered / acid- free backing boards and boxes available on the market (not the same as microchamber technology but they are still a step up from non-buffered goods). If using buffered backing boards it is not a bad idea to slip a piece of microchamber paper in between the art and the backing board as fail-safe. Boards using Microchamber technology have the term "ArtCare" in their name.
