Each of a pair of clean packaging films comprises a base structure consisting of a base layer and a heat-sealing layer, an outer protective film, and inner protective film. The pair of clean packaging films are superposed after the outer and the inner protective films are peeled off, and the superposed pair of packaging clean films are sealed properly to obtain pouches having clean inside and outside surfaces.
