<p>PURPOSE:To obtain a dehumidifying packing bag having a structure easy to produce by dividing a synthetic-resin film bag into the upper and lower compartments at a lateral perforated sealing part and forming a gas-permeable microporous membrane sheet impermeable to water at atmospheric pressure on the side face of the upper compartment. CONSTITUTION:A bag is made from a synthetic-resin film, the lower sides are bent and bonded by the sealing parts of the left and right sides and the sealing part 3 of the upper side, and the center is divided by a perforated sealing part into upper and lower compartments 5 and 6. A microporous membrane sheet 7 is laterally provided on one side face of the upper compartment 5 in the form of a band, and a deliqtuescent moisture absorbent 8 is packed in the compartment 5. Consequently, the non-sealed part of the perforated sealing part is used as the passage for the deliquescent liq., and the structure is simplified.</p> |
