A film-like molded product made of laminated materials selected from gum arabic, pullulan, starch and gelatin was published in JP-A-60-7.
6:336. Among these polysaccharide cubes, mixtures of alginate and alginic acid derivatives, which are made into water-insoluble hydrogel binder fibers, are disclosed in JP-A-62-141)99 and JP-A-63- This method is known from Japanese Patent No. 12718.

の簡易包装化及び即席化を満足するものである。This film-like molded product is edible and is used as food packaging. This film-like molded product is soluble in hot water, does not become sticky or leave fingerprints when wet, has sufficient film strength even when it comes in contact with water, has high gas barrier properties, and is transparent. Since it has heat-sealing properties, it satisfies the need for simple packaging and instant packaging as one direction for food packaging.
また、これらヒドロゲル系バインダー繊維は自己接着性

、単独で抄造することができないバルブ状物や短繊維を
抄造するのに用いられるものである。In addition, these hydrogel binder fibers do not have self-adhesive properties, or even if they do, they are very small, so they are used to make bulb-shaped objects and short fibers that cannot be made by themselves. .

できるものである。In a dry state, this hydrogel-based binder fiber has interfiber binding strength and maintains its paper shape, but in water it absorbs water and becomes a hydrogel, losing its interfiber binding strength. Therefore, the hydrogel-based binder fiber With a shearing force comparable to that of the water flow from the flush valve of a flush toilet, it can be dispersed into individual fibers such as bulb-shaped objects and short fibers, which was previously considered difficult.

おり、他の水溶性多糖類では使用できない。Moreover, the above-mentioned hydrogel-based binder fiber is a binder and does not constitute the paper itself. To make paper, another bulb-like object, short mm, is required. Therefore, these binder fibers cannot be used in applications where short fibers are undesirable.Furthermore, since this binder fiber is a mixture of alginate and alginic acid derivatives, the materials are limited, and other water-soluble Cannot be used with polysaccharides.

とを見出し、本発明に到達したものである。[Means for Solving the Problems J] The present invention has been conducting research for many years on agar and other gelling agents having various properties, and methods for producing them. The inventors believe that producing paper only with water-soluble natural polymer compounds such as agar and carrageenan, or by combining them with cellulose-based bulb-like substances and short fibers, is a In order to expand the uses of natural polymer compounds, we conducted intensive research to make paper from water-soluble natural polymer compounds. As a result, by applying the content disclosed in Japanese Patent Application No. 62-155925 by the present applicant, by blowing out an aqueous solution in which water-soluble polysaccharides are in a sol state in alcohol, water-soluble polysaccharides are made into fibers. The inventors discovered that paper could be produced by precipitating the precipitate and making paper from it, leading to the present invention.

This paper is made of water-soluble polysaccharide and is characterized by the following.

It consists of gum arabic, curdlan, diene gum, pectin, and pullulan, either alone or in a mixture of two or more thereof, and is soluble in water or hot water. The water-soluble polysaccharides mentioned above are not particularly limited as long as they are produced by conventional methods. However, if the paper made of water-soluble polysaccharides needs to be edible, they must be edible and non-toxic. The solvent used in the present invention is not particularly limited as long as it exhibits poor solubility in the water-soluble polysaccharide and hydrophilicity in water. Usually, among lower alcohols, methanol, ethanol,
Propanol, inpropanol, butanol are used. Ketones may also be used; generally, ethanol is used when paper made of water-soluble polysaccharide is used for food, and acetone is used for other uses.

The optimum temperature range for maintaining the sol state of water-soluble polysaccharides must be determined in advance depending on the type of water-soluble polysaccharide, as the optimum temperature range varies slightly depending on the type of water-soluble polysaccharide and also depends on the concentration of the aqueous solution. generally 0 to 90
C. If the temperature is low, Class I materials with gelling properties, such as agar and carrageenan, will gel.

できる。If the above temperature is high, problems such as evaporation of solvents such as alcohol occur. Further, the concentration of the water-soluble multi-JIB aqueous solution is selected in the range of 0.1 to 15% by weight. This is related to the amount of solvent added, which will be described later, and if the concentration of the aqueous solution of water-soluble polysaccharide is high, the amount of solvent can be reduced.

わることにより、溶媒の濃度が低下し、ゾル状態の水溶
性多糖類の沈殿効果が低下するのを防ぐためである。The concentration of this solvent is always adjusted to be in the range of 50.0 to 99.9% by weight, preferably in the range of 70 to 75% by weight, based on the sum of the aqueous solution of water-soluble polysaccharide and the solvent. The reason for this is to prevent the addition of the aqueous solution of the water-soluble polysaccharide to the solvent, which lowers the concentration of the solvent and reduces the precipitation effect of the water-soluble polysaccharide in the sol state.
