Abstract
A gaseous component treatment sheet of the present invention has a gas-permeable base film and a particulate remover for removing a predetermined gaseous component, and the particulate remover is dispersed in the base film. A protective layer and/or an adhesive layer can be laminated further on the base film. Since the gaseous component treatment sheet is a sheet-like member including the base film for holding the particulate remover, the size and the shape can be adjusted easily.
Claims12
A gaseous component treatment sheet comprising a gas-permeable base film and a particulate remover for removing a predetermined gaseous component, the particulate remover being dispersed in the base film, and comprising an adhesive layer, and the adhesive layer is arranged as an outermost layer,
- wherein the base film is a stretched porous film comprising polytetrafluoroethylene,
- wherein the average pore diameter of the base film is from about 0.01 microns to about 100 microns,
- wherein the gaseous component treatment sheet further comprises a gas-permeable protective layer, and the protective layer is laminated on the base film, and
- wherein the protective layer (i) does not contain particulate remover, and (ii) holds the particulate remover within the base film.
