<p>PROBLEM TO BE SOLVED: To make it possible to absorb only vapor without draining water from a desiccant container by sealing a desiccant material in a vapor permeable laminated packaging material using an unwoven film whose inner face edge part is heat-sealed as the structure of the desiccant container. SOLUTION: This desiccant container 10 for absorbing and fixing a liquid is of such a structure that a desiccant material 14 is sealed in a desiccant packaging material 12. The desiccant packaging material 12 is preferably a laminated packaging material comprising a non-coated finely porous or unwoven film layer (hereafter called 'unwoven film layer') adhered to a non-coated vapor permeable laminated film layer 22. The unwoven film 16 is basically gas- permeable but is not-water permeable if there no difference in the atmospheric pressure between the outside and the inside of the film. Besides, said film is prepared in such a manner that the pore size falls within the range of about 0.01-50μm. In addition, the rate of vapor permeation of the non-coated laminated film is set lower than that of the unwoven film.</p> |
