Abstract
The object of the present invention is to provide an single-dose package containing an internal adsorbent wherein the internal adsorbent is not trapped in the heat-sealed region thereof. In addition, the object of the present invention is to provide a single-dose package containing internal adsorbent wherein adhesion of the internal adsorbent around the vacuumed open region thereof is slight, whereby the internal adsorbent does not spill out on opening the package. The object of the present invention can be solved by a single-dose package characterized in that the internal adsorbent is tight-packed using a packaging material having a mean specific surface resistivity of from 4.4×109Ω or more to 1.0×1016Ω or less at its internal surface, under warming and/or reduced pressure.
