【発明が解決しようとする課題】上記したような従来技
術にはつぎのような解決すべき課題が存在している。第
１に、たばこ栽培農家の栽培面積の拡大によって、多量
の乾葉を保存する適当な場所が少なくなった。そのた
め、直射或いは散乱日射及び湿気の侵入が頻繁に起こっ
ている。従って、湿気の透湿が少ない被覆資材が望まれ
ていた。The above-mentioned conventional techniques have the following problems to be solved. First, the growing area of tobacco farmers has reduced the number of suitable places to store large amounts of dry leaves. Therefore, direct or scattered solar radiation and intrusion of moisture frequently occur. Therefore, there has been a demand for a coating material having a low moisture permeability.

て、被覆資材の内部に隙間から侵入した湿気を吸収する
被覆資材が望まれていた。Secondly, no matter what kind of preservation method is used at present, the current material for covering the dry leaves cannot completely block the flow of air, so that the dry leaves absorb moisture especially in bad weather such as long rain, Deterioration, excess water, and mold. Therefore, there has been a demand for a covering material that absorbs moisture that has entered the inside of the covering material through a gap.
【０００８】第３に、可視光線透過率が高い合成樹脂袋

まれていた。Thirdly, when a synthetic resin bag having a high visible light transmittance is used, the dry leaves are decolorized mainly by ultraviolet rays in the sunlight, and in the Burley species, the quality is said to be white blurred leaves. Leaves develop. Furthermore, the temperature of the dry leaves rises due to the amount of heat of solar radiation, causing abnormal fermentation, deterioration and deterioration of quality. Therefore, a coating material having a low light transmittance has been desired.
【０００９】第４に、すべての乾葉を上記の管理方法に

って、保存管理が省力化される手段が望まれていた。Fourthly, the preservation and management of all the dry leaves by the above-mentioned management method requires a great deal of labor, and in addition to the labor shortage of the farmers, it is a great burden on the tobacco cultivation farmers. In addition, sun sterilization at the time of exposure is accompanied by decolorization of dry leaves and production of white blurred leaves for the above reasons. Therefore, a means for saving labor in storage management has been desired.
【００１０】第５に、在来種とバーレー種の乾燥は自然

止することができる。The method of using the sheet for storing dried leaf tobacco constructed as described above will be described. Generally, the leaf is covered and stored so as to surround the periphery of the dried leaf. Further, in the case of storing dried leaf tobacco configured as described above, the dried leaf is housed and stored in a case formed in a box shape or a bag shape. Even if direct sunlight or scattered solar radiation enters the storage place, the light transmittance of the synthetic resin film that is the outer layer film is 6
Since it is 0% or less, the amount of solar radiation does not penetrate so much, the temperature of the inner dry leaves does not rise, and abnormal fermentation does not occur, so there is no deterioration or quality deterioration. Further, it is possible to prevent the discoloration of dry leaves caused by sunlight and mainly ultraviolet rays and the production of white blurred leaves.

/ M 2 · day or less, moisture that has entered the storage place due to long rain or the like hardly permeates inside, and further penetrates through the gaps of the storage sheet of the present invention coated so as to surround the periphery of dry leaves The moisture thus absorbed is absorbed by the water absorbent resin disposed on the inner surface. Therefore, since the dry leaves hardly absorb moisture, it is possible to prevent deterioration, excessive water content and generation of mold. Further, the moisture-permeable film covering the water-absorbent resin has a high moisture-permeability of 100 g / m 2 · day or more, so that the moisture released from the dry leaves can be transmitted, and the water-absorbent resin can absorb the moisture. Therefore, there is almost no need to manage during storage, which is extremely labor-saving.

Moisture that has entered through the gaps of the storage sheet of the invention is absorbed by the water absorbent resin 4 in the storage sheet. Therefore, since the dry leaves hardly absorb moisture, it is possible to prevent deterioration, excess water, and mold. Furthermore, since the moisture-permeable film 2 has high moisture permeability and the water-absorbent resin 4 is present, it is possible to absorb the moisture of the slightly moist dry leaves at the start of storage. Therefore, there is almost no need to manage during storage, which is extremely labor-saving.
