<p>PURPOSE:To reduce packing cost by facilitating the integration of a container requiring dehumidification with an adsorbent by enabling the direct coating of the container, by adding a hygroscopic adsorbent to a hot melt compound under mixing. CONSTITUTION:For example, a styrene/ethylene/1-butene block copolymer, an ethylene/vinyl acetate copolymer and a hydrogenated 9C petroleum resin are mixed under heating and, after synthetic zeolite was added to the resulting mixture under mixing, polyethylene wax and liquid paraffin are further added thereto to obtain a hygroscopic coating agent. This coating agent is applied to a sheet material to constitute a hygroscopic sheet which is, in turn, cut into an arbitrary size and the cut sheets are charged in a container to be dehumidified or the container is constituted of the sheet to perform the dehumidification of the container.</p> |
