い。 Traditionally, such films include ethylene film and polyethylene laminated paper, but these do not have water dispersibility and cannot be disposed of directly into sewage, seawater, or soil, and must be disposed of separately. Since this method requires additional processing, it is not actually suitable for use in films in the above-mentioned fields.

ルムを提供することにある。Problems to be Solved by the Invention The present invention is suitable for use in the above-mentioned fields of application, exhibits good water resistance within a certain period of time during use, and is suitable for use in sewage, seawater, and other water sources along with the contents of the film at the time of use. Another object of the present invention is to provide a water-soluble film that quickly disperses and dissolves in water even when disposed of in soil, and exhibits temporary water resistance without causing problems in terms of environment, hygiene, and pollution.
以下本考案を詳しく説明する。 The present invention will be explained in detail below.

したものの縦断面図を示したものである。 The structure of the present invention will be explained based on the attached drawings. The drawings show a longitudinal cross-sectional view of a water-soluble film 1 coated on one side with a hydrophobic material 2.

し、疎水性材料２の厚みを0.1〜10μmと非常に薄
くするものである。 In order to coat one side of the water-soluble film 1 with such a hydrophobic material 2, it is preferable to coat one side of the film 1 with a solvent solution or dispersion of the material 2, but it is also possible to coat one side of the film 1 with a solvent solution or dispersion of the material 2. Coating can also be performed by techniques such as polymerization, low-temperature plasma polymerization, and even vacuum evaporation. However, the thickness of the hydrophobic material 2 is made very thin at 0.1 to 10 μm.
上記疎水性材料２の被覆に際しては、該材料の
厚みが0.1〜10μmになるように行う。上記厚みが
0.1μm未満では、フイルムが使用期間中に溶解す

期間後であつてもフイルムが分散、溶解せず、所
望の目的が達せられなくなる。 The coating with the hydrophobic material 2 is carried out so that the thickness of the material is 0.1 to 10 μm. The above thickness
If the thickness is less than 0.1 μm, the film will dissolve during use, resulting in insufficient water resistance for practical use. On the other hand, if the thickness exceeds 10 μm, the water resistance becomes excessive and the film does not disperse or dissolve even after a period of use, making it impossible to achieve the desired purpose.

で、実用上極めて有用である。 Therefore, according to the present invention, the thickness of the hydrophobic material 2 is
When one side of the water-soluble film 1 is coated with a thickness within the range of 0.1 to 10 μm, due to the interaction between the material 2 and the water-soluble film 1, it has the contradictory properties of temporary water resistance and dispersion solubility in water. Therefore, it is extremely useful in practice.

利用することができる利点がある。 As described above, the single-sided coated water-soluble film of the present invention has the above-mentioned performance, so it can be used as a leak-proof membrane for sanitary napkins, filth from artificial anus users, etc.
Alternatively, if seeds or the like are packaged so as to be in contact with the surface of the hydrophobic material 2, the package can be naturally decomposed after a certain period of time, which has the advantage of being able to be effectively used for various purposes.
