  • Patent number: 8268421
    Abstract: A packaging bag and a drying agent with a moisture absorption indicator function are provided without using a heavy metal harmful to the human body. The packaging bag includes a first packaging material (10) and a second packaging material (20). The first packaging material (10) is provided on an outermost side thereof with a transparent barrier film (12) having a barrier property against water vapor. The second packaging material (20) has a light-reflective or light-absorbing film (24) and a pattern printed layer (23) overlaid on a bag interior side thereof, the pattern printed layer (23) having a printed moisture-absorbing indicator pattern (30). A desiccant-containing resin film (11, 21) which becomes transparent due to moisture absorption is overlaid on a bag interior side of at least one of the first packaging material (10) and the second packaging material (20).

  • Patent number: 7743642
    Abstract: A moisture absorbent material (drying material) with an indicator function is provided without the use of cobalt chloride containing a heavy metal, low molecular organic substance and the like; and a humidity indicator permitting a state of humidity to be found in a simple manner is also provided. The moisture absorbent material with an indicator function (10) includes a resin layer (11) containing 5 to 80 wt % zeolite which is provided on at least one surface thereof with a printed layer including a character, shape, picture or the like, so that the printed layer may visibly appear due to the resin layer becoming transparent by moisture absorption.

  • Publication number: 20080193704
    Abstract: The object of the present invention is to provide the adsorbent film and the organic EL device comprising the adsorbent film, wherein the water remained within the organic EL device can rapidly adsorb to hold without detaching, the water derived from the circumference can adsorb in a long period, gases as remained or generated in the device, including acidic gases, can adsorb, the life span of the organic EL element can be extended, the workability thereof is superior, it has the sufficient ability of drying, and the moisture adsorbent function can be obtained even in the normal temperature and high-temperature environments. According to the present invention, the adsorbent film and organic EL device comprising the adsorbent film are characterized in that the adsorbent film comprises the resin and the desiccant, it has at least two of moisture adsorbent layers, at least one of the layers contains the chemically-adsorptive desiccant, and the other contains the physically-adsorptive desiccant.
