<P>PROBLEM TO BE SOLVED: To provide a high performance porosity adsorption film which is a porous adsorption film using an adsorbent which has a desirable water vapor adsorption characteristic also suitable for humidity control application, and the adsorbent does not desorb, and moreover which can easily control the amount of the adsorbent, and can fully demonstrate the adsorption ability capacity of the adsorbent itself. <P>SOLUTION: The porous adsorption film comprises extending, in a uniaxial direction at least, a film which includes a mixed composition containing at least one sort of a thermoplastic resin (A) and an adsorbent (B) as a principal component. The adsorbent (B) is an ALPO zeolite, and has the relative vapor pressure region in which the change of the adsorption amount is at least 0.1 g/g when the relative vapor pressure varies in 0.15 in the range of at least 0.01 and at most 0.5 of the relative vapor pressure in the water vapor adsorption isotherm measured at 25°C. <P>COPYRIGHT: (C)2012,JPO&INPIT |
