ABSTRACT:
Polytetrafluoroethylene porous film is laminated with an ultra high molecular weight polyolefin porous film to realize excellent formability, dust collecting ability, and permeability that could not be attained by these porous films used alone. The laminate, which can be formed to prescribed shape if desired, is used to make a container for holding an adsorbent.
