<p>PURPOSE:To protect a material to be packed from humidity and external impact, by enclosing a necessary amt. of a moisture absorbent to contact at least with a moisture permeable membrane between a flexible material and the moisture permeable membrane, providing elastic layer and composing a dehumidifying material. CONSTITUTION:An intermediate partition 2 composing a flexible material 1 and having wave-shaped or gutter-shaped irregularity is brought into adhere on the one side of the flexible material 1 such as plastics of every kind, metallic foil or waterproof paper. The dehumidifying material 7 is formed by packing the absorbent 5 into the partition chamber 4, which is obtained by cutting a dent 3 in the intermediate partition 2 to the longitudinal direction, allowing the moisture permeable membrane made of moisture permeable material to adhere to the intermediate partition 2 and enclosing the moisture absorbent 5. In the case of using the dehumidifying material 7 as a dehumidifying packing material, the material is cut in a desired size at the part where no absorbent 5 is packed and the the material to be packed such as a precision instrument is packed to contact with the inside of the moisture permeable membrane 6.</p> |
