摘要:
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. The humidity indicator (20) is formed by laminating a film (21) made of a zeolite-containing resin composition, a polyolefin film (22) having patterns (24) printed thereon that include characters, symbols, lines or the like, which are printed to have a difference in the print density, and an aluminum foil (26) through an adhesive, so that the patterns (24) may be made sequentially visible due to the film (21) made of the zeolite-containing resin composition becoming transparent by moisture absorption.

摘要:
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). The drying agent with a moisture absorption indicator function includes an indicator film layer (70) having a barrier film (75), a pattern printed layer (73) for a moisture absorption indicator, and a moisture-absorbing film (71) containing zeolite, the pattern printed layer (73) and moisture-absorbing film (71) being laminated in this order on the barrier film (75). The drying agent further includes a main desiccant layer (61) and a moisture permeable film (64) that are overlaid on the moisture-absorbing film (71).

摘要:
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.
